Chapter Introduction 1 This chapter introduces Field Control modules, the Genius Bus Interface Unit, and other equipment that may be used with the Bus Interface Unit. It will help you locate more information in other Field Control and Genius documents. Overview Bus Interface Unit I/O I/O I/O Field Control is a family of highly modular distributed I/O and control products. They are suitable for use in a wide range of host architectures.
1 Field Control Modules There are three basic types of Field Control modules: Bus Interface Unit. The illustration below shows a Genius Bus Interface Unit. I/O modules Micro Field Processor Terminal Blocks: Bus Interface Unit Terminal Block. I/O Terminal Blocks, each of which accommodates two I/O modules. Auxiliary Terminal Blocks. These optional terminal strips can be connected to the side of an I/O Terminal Block if extra common terminals are needed.
1 Genius Bus Interface Unit The Genius Bus Interface Unit (IC670GBI002 or IC697GBI102) interfaces Field Control I/O modules to a host PLC or computer via a Genius bus. It can exchange up to 128 bytes of input data and 128 bytes of output data with the host, each Genius bus scan. It can also handle Genius datagram communications.
1 I/O Terminal Blocks and Auxiliary I/O Terminal Blocks An I/O Terminal Block provides mounting, electrical, and field wiring connections. Each half of the I/O Terminal Block can be mechanically keyed to accept only an I/O module of a specific type. Auxiliary I/O Terminal Blocks can be easily attached to an I/O Terminal Block. They can be used to provide additional common terminals if needed.
1 Environmental Specifications Vibration Noise Modules perform well where vibration is a factor. Designs are shock and vibration tested to meet the following specifications when installed on a panel-mounted DIN rail using the clamp supplied, and with the panelmounting feet secured: IEC68-2-6: 10 to 57 Hz 0.
1 Configuration for Field Control Configuration is an important part of the process of setting up a Field Control station.
1 Field Control in a Genius System Using Field Control modules on a Genius bus combines the low cost, small size, and flexibility of Field Control with the versatility, power, and communications features of the Genius system. The Genius bus is an industrially-hardened Local Area Network (LAN). It passes I/O (control) data and background information (datagrams) between the Bus Interface Unit and a Genius bus controller. A Genius bus can support up to 32 devices.
1 A More Complex Field Control and Genius System A more complex communications and control system is illustrated below. In this system, the Field Control stations and Genius blocks on the lower left are controlled by a Series 90-70 PLC. The Field Control stations and Genius blocks on the lower right are controlled by a host computer equipped with a PCIM (Personal Computer Interface Module). The PLC communicates with a computer running programming software via an SNP (Serial Network Protocol) link.
1 Required Genius and Host System Equipment The following system equipment is required: Genius Hand-held Monitor version 4.6 (IC660HHM501J) or later. For a Series 90-70 PLC Series 90-70 CPU firmware, release 3.0 or later. A Series 90-70 Genius Bus Controller, release 3.0 or later. The Bus Controller must be 4.0 or later for full diagnostics display from Logicmaster 90-70, or for redundancy applications.
1 Using Field Control in a CPU Redundancy System Most systems use only one Bus Controller and CPU to control the I/O on the Genius bus. CPU redundancy, which can be used for backup CPU/Bus Controller protection in critical applications, is described in detail in the Genius documentation. The section that follows here summarizes how Field Control products can fit into a Genius CPU Redundancy system.
1 Using Field Control in a Genius Bus Redundancy System In Genius bus redundancy, there are two bus cables each connected to a Bus Controller. I/O devices may be connected to either one bus of the pair, or to both. However, a device that is connected to both busses actually communicates on only one bus at a time. Before the alternate bus can be used for communications, a bus switchover must occur and the device must “log in” with the Bus Controller(s) on the alternate bus.
1 A Bus Interface Unit can be located on a bus stub. A Bus Interface Unit can also be located on a bus stub, which is a short length of unterminated cable downstream of either a Genius I/O block/Bus Switching Module combination, or a Remote I/O Scanner connected to a dual bus. Because the bus stub cable itself is not redundant, this type of installation does not provide as much protection as connecting directly to a dual bus.
Chapter Description 2 This chapter describes: Genius Bus Interface Unit Bus Interface Unit Power Supply Bus Interface Unit Terminal Block Specifications Genius Bus Interface Unit The Genius Bus Interface Unit is a small, rugged, intelligent module with a sturdy aluminum housing. The module has four status LEDs, described below, and a connector for attaching a Genius Hand-held Monitor. 3.25" (8.2mm) HHM Connector 5.0" (12.
2 LEDs The LEDs on the Bus Interface Unit show its operating status. lights to indicate that +5V power is available for logic operation. OK lights to indicate that the module has passed its powerup diagnostic tests. See the table below for more information. RUN lights only if output modules are in the BIU configuration and are written to by the controlling bus controller. See the table below.
2 Bus Interface Unit Power Supply The power supply in the Bus Interface Unit provides power for the Bus Interface Unit itself and logic power for all I/O modules that may potentially be installed at that station. External power must be supplied for field wiring of input and output devices. The power supply is not damaged by either of the following: Reversing input voltage on terminals 1 and 2. Temporary overcurrent conditions on the 6.5 VDC output.
2 Backplane Current With a DC input voltage, the amount of current available to the backplane may be limited by lower input voltage as indicated below. For 24VDC Supply Backplane Current Available (Amps) For 125VDC Supply Backplane Current Available (Amps) 1.4 1.2 1.0 18 2.0 1.8 105 110 19 21 Voltage In Voltage In Calculating Input Power Requirements for a Bus Interface Unit The charts below show typical input power requirements for a Bus Interface Unit.
2 Bus Interface Unit Power Dissipation The Bus Interface Unit power dissipation can be determined once the backplane current supplied to the I/O modules is known. The following equation can be used to calculate BIU power dissipation: BIU Power Dissipation = Input Power - (total backplane current x 6.5 volts) For example: A. Total backplane current = 0.5 Amps B. Typical Input power = 7.7 Watts Therefore: BIU Power Dissipation = 7.7 W - ( 0.5 x 6.5 ) = 4.
2 Load Requirements for Hardware Components The table below shows the DC load required by each module and hardware component. All ratings are in milliamps. Input and Output module current ratings are with all inputs or outputs on. These are maximum requirements, not typical.
2 Hot Insertion/Removal of Modules Bus Interface Units IC670GBI002(F) and IC670GBI102A or later support Hot Insertion/Removal of modules in the I/O Station. Hot Insertion/Removal means that modules can be removed and replaced while I/O Station power is applied without affecting the BIU or other modules in the I/O Station. Separate I/O module power must be switched off to the module being inserted or removed.
2 Bus Interface Unit Terminal Block The Bus Interface Unit provides terminals for power and ground connections. Maximum wire size is AWG #14. (avg 2.0690mm2 cross-section). The Bus Interface Unit Terminal Block also has eight input terminals for connection to a single or dual Genius bus. These terminals accommodate up to two AWG #14 wires. The Bus Interface Unit Terminal Block contains bus-switching circuitry permitting it to be used as a BSM Controller in a dual bus redundancy system.
2 Functional Specifications Bus Interface Unit: Reliability More than 183,000 hours operation MTBF, calculated 24VDC Power Supply Input Nominal Rated Voltage 24 VDC Voltage Range 18 VDC to 30 VDC Power 16.8 Watts maximum at full load (nominal voltage) Inrush Current 15-50 Amps peak, 3 mS maximum. Inrush current is installation dependent. See page 2-4. Power Supply Output to I/O modules: 6.5 VDC ±5% 1.4 Amp maximum. See page 2-4. Holdup Time 10mS maximum from nominal input voltage.
Chapter Installation 3 This chapter describes: System Wiring Guidelines System Grounding Locations for Field Control Modules Installing the Bus Interface Unit Terminal Block on a Panel Installing the Bus Interface Unit Terminal Block on a DIN Rail Installing the Cables Between Terminal Blocks Power Wiring to the Bus Interface Unit Connecting the Communications Bus Installing/Removing the Bus Interface Unit Removing/Replacing the Bus Interface Unit Fuse Upgrading
3 Preinstallation Check Carefully inspect all shipping containers for damage during shipping. If any part of the system is damaged, notify the carrier immediately. The damaged shipping container should be saved as evidence for inspection by the carrier. As the consignee, it is your responsibility to register a claim with the carrier for damage incurred during shipment. However, GE Fanuc will fully cooperate with you, should such action be necessary.
3 System Wiring Guidelines Four types of wiring may be encountered in a typical factory installation: 1. Power wiring - the plant power distribution, and high power loads such as high horsepower motors. These circuits may be rated from tens to thousands of KVA at 220 VAC or higher. 2. Control wiring - usually either low voltage DC or 120 VAC of limited energy rating. Examples are wiring to start/stop switches, contactor coils, and machine limit switches.
3 System Grounding All components of a control system and the devices it controls must be properly grounded. Ground conductors should be connected in a star fashion, with all branches routed to a central earth ground point as shown below. This ensures that no ground conductor carries current from any other branch.
3 Locations for Field Control Field Control terminal blocks must be installed on a 35mm x 7.5mm DIN rail. Modules can be located on equipment, in junction boxes, inside panels, behind operator stations, in NEMA enclosures as little as 4" deep, and in other locations where space is limited. The area should be clean and free of airborne contaminants, with adequate cooling airflow. Modules can be mounted in any orientation without derating the temperature specification.
3 Mount the DIN rail at least 4.25 inches (10.80 cm) from any wireway or other obstruction on the wiring side of the Bus Interface Unit. Allow more space if the wiring for I/O modules is very stiff. A wiring template is also provided in the instruction sheet included with each Bus Interface Unit terminal block. Drill mounting holes for the BIU Terminal Block as shown below. Allow a small tolerance between the top and bottom of adjacent terminal blocks.
3 Installing the Bus Interface Unit Terminal Block on the DIN Rail 1. Tilt the Bus Interface Unit Terminal Block and position it over the rail, as shown below left, catching the rail behind the tabs in the terminal block. 2. Pivot the terminal block downward until the spring-loaded DIN rail latches in the terminal block click into place. 1 2 tabs 3. DIN rail Tighten the DIN rail clamp screw (see below left). Recommended torque is 4 to 6-in/lbs.
3 Installing the Cables Between Terminal Blocks Before installing modules on their terminal blocks, install the connecting cable(s) between terminal blocks. A short connecting cable, as illustrated below, is supplied with each I/O Terminal Block. A set of three connecting cables is available as renewal part number IC670CBL001. Optional 21-inch (0.53 meter) cable is also available (IC670CBL002) (only one 21" cable can be used per Field Control station).
3 Power Wiring to the Bus Interface Unit Note: Do not apply power until the BIU module is installed on the Terminal Block. 1. Connect an appropriate power source as shown below. Low Voltage Connections (IC670GBI002) High Voltage Connections (IC670GBII02) 24 VDC + 115VAC or 125VDC For BIU version IC670GBI102, if a DC supply is used the polarity is not important. BIU version IC670GBI102 provides internal overvoltage protection.
3 Connecting the Communications Bus The Bus Interface Unit Terminal Block has a two sets of bus terminals. The terminals in the center portion of the terminal block are for the main bus cable; they are always used. The outermost set of bus terminals is for an optional redundant (dual) bus cable. The Bus Interface Unit Terminal Block has built-in bus switching capability; do not attach a Bus Switching Module in a dual bus application.
3 Making Bus Connections 1. 2. 3. Connect Serial 1 to the Serial 1 terminals of the previous device and the next device. Connect Serial 2 to the Serial 2 terminals of the previous device and the next device. Connect Shield In to Shield Out of the preceding device. Connect Shield Out to Shield In of the next device. If the Bus Interface Unit is the first device on a bus, Shield In can be left unconnected. If it is the last device on a bus, Shield Out can be left unconnected.
3 Installing Pre-Molded Bus Cables Pre-molded cables must be installed in the orientation shown below. The main bus cable exits toward the power connections. The optional redundant bus cable exits away from the power connections.
3 Bus Connection for Critical Processes Bus connections are normally considered permanent. They should never be removed while the bus is in operation; the resulting unreliable data on the bus could cause hazardous control conditions. If the bus controls critical processes that cannot be shut down, the Terminal Block can be wired to the bus via an intermediate connector as shown below.
3 Installing the Bus Interface Unit on the Terminal Block End View 1. Before installing a new Bus Interface Unit, remove the cable slot knockout on the end of the module that will cover the connecting cable. It can be removed with pliers, or by pressing out from inside the module housing. 2. Power to the I/O Station should be OFF. 3. To install Bus Interface Unit on the terminal block, position the module so that the cable slot in the module housing is over the connecting cable.
3 Removing/Replacing the Bus Interface Unit Fuse If all the Bus Interface Unit LEDs go off, it may be necessary to replace its fuse. The fuse can be removed without disturbing any other parts of the station or wiring. 1. To check the fuse, remove power from the station. Caution Avoid touching the exposed wiring on the Terminal Block when removing the Bus Interface Unit. Caution Electrostatic discharge can damage the module when it is not installed on a Terminal Block.
3 Upgrading the BIU Firmware Note The BIU EEPROM stores the configuration of the I/O Station. If you replace the BIU EEPROM, it will be necessary to reconfigure the I/O Station using a Handheld Monitor. Follow the steps below to replace the BIU's firmware EEPROM. Caution Avoid touching the exposed wiring on the Terminal Block when removing the Bus Interface Unit. Caution Electrostatic discharge can damage the module when it is not installed on a Terminal Block.
3 Note the position of the card guide with respect to the metal housing for reassembly. 46547 card guide 4. Hold your hand behind the module to retain the board set, and turn the module face up. 5. Insert a small screwdriver or similar tool into either of the holes from which you previously removed the module retaining screws. Pry the two halves of the plastic latch inward to free that side of the card guide. Repeat on the other side. 46548 latch 7.
Chapter Operation 4 This chapter explains how a Bus Interface Unit interacts with the modules in its station, how it stores data, and how it exchanges data with the system host.
4 BIU Data Handling at the I/O Station The BIU manages all movement of data within the I/O station and between the I/O station and the Genius bus. The BIU scans the I/O modules in the station, exchanges data with the host, and can manage the exchange of data between a Micro Field Processor and other modules in the station. In addition to its regular I/O scanning capabilities, the BIU can also selectively transfer specific data groups from one intelligent module in the station to another.
4 I/O Data for Conventional Modules Conventional I/O modules provide or receive just one type of I/O data (sometimes referred to as reference data). Normally, this data is assigned to the data types shown below; however, any module's data can be assigned to any data type in BIU memory.
4 Group Data for Intelligent Modules Intelligent modules can also be configured for "Group" data transfer with the BIU or with other intelligent devices in the same Field Control station. A data group is a selected set of data that the BIU transfers from one location to another location in the station. The BIU can transfer the group data during every sweep of its operations, or only during specified sweeps.
4 The BIU Sweep 46543 1 Read all inputs from conventional discrete and analog input modules The "sweep" of the Bus Interface Unit is the sequence of actions it executes repeatedly as long as the module is receiving power.
4 6 Move Input Data to the Communications Buffer The BIU then moves all current discrete and analog input values presently in its network map into a memory buffer, in preparation for transmitting them on the Genius bus. 7 Move Output Data from the Communications Buffer After moving the inputs into the communications buffer, the BIU moves newly-received output data from the communications buffer.
4 BIU Backplane Scan Time The backplane scan time for the Genius BIU depends on: the type and number of modules present in the Field Control station, the scan time of the Genius bus, and the number and type of Group Data Move definitions. Shorter Genius bus scan times typically impose more overhead on the BIU, increasing backplane times. Longer Genius bus scan times tend to reduce the overall load to the BIU and thus slightly decrease backplane scan times.

4 Data Transfer Between the BIU and the Host Each bus scan, a Bus Interface Unit exchanges the following data with the host: It sends an input message with up to 128 bytes of discrete and/or analog inputs. It receives an output message with up to 128 bytes of discrete and/or analog outputs. The exact length of these messages is determined by the network I/O map configured for the Bus Interface Unit.
4 Input Data Sent by the Bus Interface Unit When the Bus Interface Unit takes its turn on the bus, it sends one input data message containing the latest values for all configured discrete inputs followed by all configured analog inputs. Because they are broadcast (like all Genius inputs), they can be obtained by any Bus Controller on the bus.
4 Outputs from the Host to the BIU Each time the host's Bus Controller has the bus communications token, it sends any outputs it has received from the CPU to the devices on the bus. Outputs for the Bus Interface Unit are sent in one output data message, with all configured discrete outputs followed by all configured analog outputs.
4 Genius Bus Scan Time The Genius bus scan time is dependent on the number of devices and amount of data traffic on the bus. The bus scan time may vary from 3-400mS, but 20-30mS is typical. Bus Controllers impose a minimum Genius bus scan time of 3mS. Therefore, Genius bus scan time can never be less than 3mS. The Genius bus scan time contribution for Field Control station depends on its I/O data usage.
4 Throughput If an output in the station is tied to an input in the same station, the output changes state (or value, in the case of an analog output module) within a few milliseconds of the new output being sent from the bus controller to the Bus Interface Unit. (To guarantee that an output changes state, that state must be present for at least one BIU sweep time or bus scan time, whichever is greater.
4 Operation of the BIU with a Micro Field Processor The Micro Field Processor (MFP) is a specialized Micro PLC that provides local input/output logic within a Field Control I/O station. The MFP itself does not perform an I/O scan; that function is performed by the BIU. MFP and BIU Synchronization Automatic operation of the Micro Field Processor must be synchronized with that of the BIU. Synchronization between the MFP and the BIU occurs at the following points: 1.
4 Synchronous Operation of a BIU and a Micro Field Processor Bus Interface Unit 1 Micro Field Processor Read all inputs from conventional discrete and analog input modules MFP Waits 2 3 4 Read all reference parameter inputs from “smart” modules * * 5 MFP receives Group Data from the BIU Read all group data moves whose destination is the BIU, except groups whose source is a Synchronization module MFP Waits Send Group Data moves to a Synchronization module Send outputs from BIU to Synchronizatio

4 Backing Up Micro Field Processor Outputs The network can back up outputs normally controlled by the Micro Field Processor if the MFP fails or goes into Stop Faulted mode. To create this backup capability for one or more output modules, do the following: 1. Configure the module outputs to lie within both the BIU's Network Map and the MFP's I/O map.
4 How the Network Backs Up MFP Outputs This technique works because of the synchronization between the operations of the Bus Interface Unit and the Micro Field Processor. The diagram below shows details of the BIU/MFP synchronization process. The numbers on the left side are the same as the numbers on the synchronization diagram.
4 Backing Up BIU Outputs with a Micro Field Processor The Micro Field Processor can take over control of outputs normally provided from the network by the Bus Interface Unit, if those outputs become unavailable. This technique requires the addition of ladder logic to the application program. To create this backup capability for one or more modules, do the following: 1.

The MFP is set to defaul (*its received data if the network disappears. Therefore when the networ (*disappears Input 17 will be OFF. Input 17 is a heartbeat detecting the (*presence of network outputs.
Chapter Station Configuration 5 This chapter explains how to configure a Bus Interface Unit and the I/O modules in a station using a Hand-held Monitor. HHM version 4.6 (IC660HHM501J) or later is required. Note that the BIU and I/O modules can also be configured via datagrams from the host. Datagram formats are detailed in chapter 8.
5 Configuring the Serial Bus Address and Baud Rate Before a Bus Interface Unit can communicate on the Genius bus, its serial bus address must be configured. That means if you install a Bus Interface Unit and power it up BEFORE configuring its serial bus address, it does not communicate on the bus. When you subsequently configure the serial bus address, the Bus Interface Unit begins communicating on the bus immediately. The baud rate must be set first in order to configure the BIU online.
5 Set Up the Hand-held Monitor 1. If the Bus Interface Unit is connected to an operating bus, the Hand-held Monitor must be the ONLY Hand-held Monitor plugged into any device on the bus. If the Bus Interface Unit is NOT presently connected to a properly-terminated Genius bus, install a 75 Ohm terminating resistor across the Main Bus Serial 1 and Serial 2 terminals on the Bus Interface Unit Terminal Block.
5 Create a New Configuration If the Bus Interface Unit has already had its Serial Bus Address configured, go to the instructions on the next page. If the Bus Interface Unit has not been assigned a Serial Bus Address, select F3 (Configuration) from the previous menu. The configuration Main Menu appears: F1:PROG BLOCK ID F2:CONFIG BLOCK F3:COPY CONFIG F4: Select Program Block ID (F1).
5 Configure the Bus Interface Unit From the HHM's Main Menu: F1:HHM UTILITIES F2:ANALYZE F3:CONFIGURATION F4:DEVICE MEMORY Press F2 twice to display the HHM's special set of menus for the Bus Interface Unit. (To display these menus, a serial bus address must have been configured for the Bus Interface Unit on the Program Block ID screen). An overview of these menus is shown on the next page.

5 Change the Serial Bus Address of the Bus Interface Unit For a new BIU, the Serial Bus Address is assigned on the Program Block ID screen, as described previously. If you want to change the Serial Bus Address of a previously-configured BIU, use the Device SBA screen shown below, instead. When you press F1 (Genius Configuration) from the Configuration menu, the following screen appears: Serial Bus Address Device SBA 14 Prv > entr Press F1 if you want to return to the previous menu.
5 Select the Baud Rate Genius bus communications can occur at any of four baud rates: 153.6 Kbaud standard, 153.6 Kbaud extended, 76.8 Kbaud, or 38.4 Kbaud. The default is 153.6 K baud standard. The Genius I/O System User's Manual gives guidelines for baud rate selection. Each device's communications baud rate must be the same as that used by all other devices on the bus, or the bus will not operate. Baud Rate? 153.5k std < 1.
5 Select a Series Six or Series Five PLC Reference Address If the network controller is not a Series Six PLC or Series Five PLC, no entry is necessary here. Press F4 (entr) to go on. If the network controller is a Series Six PLC or Series Five PLC, an I/O or register reference address must be assigned to the Bus Interface Unit. This is done on the screen shown below. Stat Tbl Addr 00000 < > IO6 entr shows reference type 1.
5 Configure Fault Reporting On the next screen, select whether or not the Bus Interface Unit will perform any fault reporting. Report Faults YES < > tgl entr If you want to set up partial fault reporting for the station, you can set fault reporting to YES here but inhibit fault reporting for some or all individual modules in the station. Instructions for setting up or inhibiting fault reporting for individual modules are included in the module configuration portion of this chapter. 1.
5 Configure Genius Bus Redundancy If the Bus Interface Unit will be used as a bus switching device itself, or located on a bus stub downstream of another device that acts as a bus switching device, BSM Present should be set to YES. For all other applications, set it to NO. BSM Present NO < 1. > tgl entr If you want to go to the next screen without making a change, press F2 ( > ). If the selection should be changed, press F3 (tgl). 2. Press F4 (entr). If you selected NO, go to the next page.
5 Configure CPU Redundancy If the Bus Interface Unit will be used on the same bus with two controllers (PLCs or network controller computers), and both of the controllers will send it outputs, the Bus Interface Unit must be set up for CPU Redundancy. The two types of CPU Redundancy, Hot Standby and Duplex, are defined below. If either type of redundancy is selected, the Bus Interface Unit will automatically provide inputs and diagnostics to both of the redundant CPUs.
5 2. Press F4 (entr). If you selected Duplex, the following screen appears: Duplex Default OFF < > tgl entr In Duplex Redundancy mode, the Bus Interface Unit may receive different output states for given points from the two CPUs. If that happens, the Bus Interface Unit "breaks the tie" by outputting the Duplex Default State to those points. 3. If you want to go to the next screen without making a change, press F2 ( > ). To change the Duplex Default state, press F3 (tgl). 4.
5 Select Configuration Protection This feature can be used to protect the station configuration. To make subsequent changes, protection must be removed again. Before the station is used, its configuration should be protected. CONFIG PROTECT Disable < > tgl entr 1. If the selection shown on line 3 should be changed, press F3 (tgl). Press F4 (entr). 2. This is the last Genius Bus Interface Unit configuration screen. Tag Name Screen Display only.
5 Configure Field Control Modules Display the Bus Interface Unit configuration menu. F1 Genius Config F2 Module Config More From the Configuration Menu, press F2 to configure the individual modules in the station. Enable/Disable the I/O Scan On the next screen, you can enable or disable the Bus Interface Unit's I/O scanning. (The Bus Interface Unit begins scanning I/O as soon as it is powered up). Disabling the I/O scan will leave inputs and outputs holding their last states.
5 Configure the Network Map for the Bus Interface Unit The next screens are used to assign the starting addresses and lengths for the Bus Interface Unit's network map. This is the data exchanged on the Genius bus. Blk Map Start ? Indicates no data type has been selected yet.
5 Configuring Extra References in the BIU I/O Map Normally, there is no need to configure extra I/O references in the BIU's network I/O map. Although unused references do not contain meaningful data, they do add to the Genius bus scan time. One circumstance under which it might be best to configure extra I/O references would be to allow for future addition of I/O modules to a station in a system where the host uses the same reference addresses for data as the BIU.
5 You might use a worksheet like the one shown below to record the I/O references and Reference Parameters configured for the Bus Interface Unit and for the modules in the I/O Station. Slot 0 is the location of the BIU. The references you enter for the BIU are the ones that will be communicated on the Genius bus. Slots 1 through 8 (maximum) contain conventional I/O modules or intelligent modules.

5 Input Scaling Based on the actual analog input signal level for a channel, the analog input module reports a value from decimal 0 to 4095 to the Bus Interface Unit. The Bus Interface Unit can convert this digital input to a value that is more meaningful to the application by using the "scaling values" configured on this screen. For each channel, two sets of values are configured: high and low "scaled" values and the actual high and low digital values they represent.
5 Alarm Limits Each input channel can have two alarm thresholds, one for a low engineering units (scaled) value and one for a high value. Maximum values are +/-32,767. The high threshold should be greater than the low threshold. Threshold limits are based on circuit scaling. If scaling is changed, review and readjust the Alarm Thresholds if necessary. Alarm Thresholds can be set anywhere over the dynamic range of the signal.

Channel Header If the BIU and Hand-held Monitor support display of channel headers, a header screen appears for each channel as shown below. S:1 CH 1 CONFIG < > zoom A. Press F2 (>) from this screen to go to the header screen for the next channel. Pressing F2 (>) from channel 8 displays the module's first reference parameter screen. B.
5 Scaling Range Scaling can be used to define a constant-slope mapping from the value in engineering units sent by the BIU to a channel's output voltage. The default scaling configuration (-10V to +10V) provides an output voltage range of -10,000 (low span value) to +10,000 (high span value) for engineering units (AI) values of -10,000 to +10,000. On this screen, specify the default range used for scaling analog output data.
5 Custom Scaling To scale a channel, choose a high and low point and enter the actual input value (span) and a corresponding engineering units value for each point. During operation, the module will use these values to convert engineering units into digital values that represent output voltage. Engineering units values are 16-bit signed integers from -32,768 to 32,767. Span values are signed integers ranging from -10,000 to +10,000 or 0 to +10,000.
5 The high span value for the channel is displayed next. S:1 CH1 SPAN H 10000 < > chg entr If the low and high span values are configured to be equal, the channel will output the same voltage for all engineering units (AQ) values. The output voltage will correspond to that low/high span value. For example, if both the low span and high span values were configured as 10,000, the output voltage for the channel would be 10V regardless of the AQ value.
5 Configure an 8-Point Analog Current Output Module S1: ALG330 1.0 F4 S1: I * I:032 I00001-00016 S:1 ALG330 1.
5 If you prefer to change the BIU table mapping, length, or reference value, press F3 (change). Then press F3 to select a data table (data type). S:1 I I Select table tgl entr To configure the selected data type, press F4 (entr). You can edit the length on this screen. S:1 I I:032 Select length clr entr Enter the new length from the keypad. Valid values are: 0, 8, 16, 24, or 32 (bits) for discrete input (data type I) data. 0, 8, or 16 bits for discrete output (data type Q) data.
5 You can edit this screen or accept it using the F4 (enter) key. The asterisk beside the data type disappears, to show that the current values have been saved. Valid values for analog output data length are 0-8. If this length is set to less than 8 and the module has not been previously configured the outputs of unused channels will go to 0mA.
5 Configure Data Defaults Data default screens are displayed next. For the module's diagnostic input bits (data type I), you can determine what the BIU should do with the data if the BIU loses communications with the module. Data can either be held at its present values or defaulted to zero. S : 1 Mo d u l e - > DE F AUL T : Z E R O < > t gl %I ent r You can accept DEFAULT: ZERO with the F4 (enter) key, or press F3 (toggle) then F4 (enter) to change the default and save it.
5 Configure Local Default Outputs Next, select the default output mode used for all channels in the event of a local (module) failure or reset. This is not the same as the data defaults described on the previous page, which are for the BIU. The choices for local default output are: A. ZERO: The output of each channel goes to 0mA in the event of a local failure or reset. B.
5 Circuit Configuration The sequence in which circuit configuration screens appear depends on the revision level of the Hand-held Monitor and the BIU. Channel Header If the BIU and Hand-held Monitor support display of channel headers, a header screen appears for each channel as shown below. S:1 CH 1 CONFIG < > zoom A. Press F2 (>) from this screen to go to the header screen for the next channel. Pressing F2 (>) from channel 8 displays the module's first reference parameter screen. B.
5 Scaling Range Scaling can be used to define a constant-slope mapping from the value in engineering units sent by the BIU to a channel's output current. The default scaling configuration (selection 1 on this screen) provides an output current range of 4mA (low span value) to 20mA (high span value) for engineering units (AI) values of 4,000 to 20,000. On this screen, specify the default range used for scaling analog output data.
5 Output Scaling If engineering and span values for a channel are entered during configuration rather than being set by a default range, “NONE” is displayed on the Default Range screen. “NONE” can then be selected again but will have no effect on the module configuration. The module performs its own scaling (unlike conventional Field Control analog modules, whose scaling is performed by the BIU).
5 The low span value is displayed next. This is the actual current in microAmps that a channel will output when the low engineering units value is commanded. Span values are changed in the same way that engineering units values are changed. Valid span values are 0 to 20,000. S:1 CH1 SPAN L 04000 < > chg entr The high span value for the channel is displayed next.
5 Configure a Micro Field Processor There are two basic steps to configuring a Micro Field Processor (MFP): 1. Configuring the MFP's Reference Parameters, as described here. Reference Parameter is the term used here to describe data (usually of more than one data type) that is transferred between an intelligent module and the Bus Interface Unit during each BIU sweep. All data exchanged by intelligent modules in a Field Control station is called Reference Parameters. 2.
5 Select Data Types for Micro Field Processor Data To configure BIU references for MFP data, use the cursor (F1, F2) keys to go through the available MFP data types. On the example screen below, the displayed MFP data type is Q (discrete outputs).
5 Enter the data length from the keypad, then press F4 (enter) to save it. The HHM displays the offset (reference address) of the first reference of the selected type that is available in the BIU. For example, if Q00001 through Q00032 were already assigned to other modules, the next available reference would be Q00033: S:7 MFPQ1 Q:016 Ref Addr 00033 < > chg entr If you enter an invalid length value or overlapping references, the HHM displays an error message.
5 Configure Group Data Moves The BIU, Micro Field Processor, and intelligent modules can also be configured for "Group" data transfer. Group data is a set of data that the BIU regularly transfers from one location in the station to another. Up to 16 data groups can be set up for an I/O station. Each group can consist of up to four separate data moves between the same two devices and in the same direction. You might use a form like the one below to record your Group Data assignments.
5 Set Up a Group Data Move To configure one or more Data Groups, begin at the Main Menu for the BIU: F1 Monitor F2 Configuration From this menu, press F2 (Configuration). This menu appears: F1 GENIUS CONFIG F2 Module Config More Press F3 to display the next configuration screen:.
5 The number in the upper right corner of the HHM screen shows the group number (1 in the example above). The 0 indicates the slot definition. For each group move, the BIU can move data in one direction, to or from any intelligent module in the I/O Station including itself. It is also possible to move data from one memory type in the BIU to another memory type in this manner. Note the following about Group Moves: 1.
5 Configure the First Move for a Group Group Move 1:1 Src Ref:%AI00009 < > tgl entr For each data type, a starting offset and length can be specified. It is not necessary to move all of a module's data of a particular type. You can specify any suitable offset and length. If the reference is to a BIU table, you must enter the actual address of the data. The BIU will calculate the offset. For a Micro Field Processor, the following data types can be read or written: R, AI, AQ, A, I, Q, M, T, G.
5 Configure the Defaults for Each Move in a Group Next, establish the defaults for each move in a Group. This determines how the BIU responds if it loses communications with the module that is the source of the data. The BIU continues performing the Group Data moves even if it is not able to read fresh data from the Source module.
5 Deleting a Group Data Move To remove one or more Data Groups, begin at the Main Menu for the BIU: F1 Monitor F2 Configuration From this menu, press F2 (Configuration).
Chapter Diagnostics and Fault Clearing 6 This chapter describes the diagnostics capabilities of the Bus Interface Unit, and explains how faults can be cleared from a Hand-held Monitor or programmer.
6 Diagnostics and Fault Clearing for the BIU and Conventional Modules The Bus Interface Unit reads faults from conventional modules in the I/O station. These faults can be viewed, and cleared from a programmer fault table or from a Hand-held Monitor. The following table lists the fault messages generated by the Genius Bus Interface Unit for module and circuit faults on conventional I/O modules.
6 Display and Clear Faults from a Genius Hand-held Monitor A Genius Hand-held Monitor can display faults from a Bus Interface Unit while attached anywhere on the Genius bus. 1. From the HHM Main Menu shown below, display the HHM's special set of menus for the Bus Interface Unit. F1:HHM UTILITIES F2:ANALYZE F3:CONFIGURATION F4:DEVICE MEMORY A. If the Bus Interface Unit is the currently-selected device, press either F3 (Configuration) or F2 (analyze) twice. B.
6 4. The Faults menu appears: F1 First 16 Flts F2 Last 16 Flts F3 Previous Menu 5. Press F1 to display the first set of 16 faults (one fault at a time). For example: Slot #1 Fault#01 EXTRA I/O MODULE Use F1 and F2 to display another fault < > Fault message exit If there are no faults, the HHM displays the message: No Faults on the top line. 6. To display the last 16 faults (if any): A. Press F4 (exit) to return to the screen shown at the top if this page. B. Press F2 (last 16 faults).
6 Display and Clear Faults from a PLC A PLC places faults from a Field Control station in the I/O and PLC Fault Tables. Series 90 PLC: I/O Fault Table The content of the I/O fault display depends on the revision level of the PLC's Bus Controller module, and the type of programmer software being used. With a Bus Controller that is version 4.
Chapter Monitoring and Controlling Field Control Data 7 This chapter explains how to monitor or control Field Control I/O data using a Genius Hand-held Monitor or a programmer.
7 Overview There are two ways to manipulate I/O data in a station: A. by forcing an input or output to assume a desired state or value that will be stored in the BIU's EEPROM memory. This is done with a Hand-held Monitor; no equipment other than the I/O module(s) is required. It can also be done using datagrams. Forces can only be applied to the portions of the BIU's internal memory that are included in the BIU's I/O map. Forces cannot be applied to references that lie outside the I/O map.
7 Monitor/Control I/O Data: Genius Hand-held Monitor A Genius Hand-held Monitor can be used to display diagnostics (see chapter 8) and current I/O states, and to force and unforce individual I/O points. 1. From the HHM Main Menu shown below, display the HHM's special set of menus for the Bus Interface Unit. F1:HHM UTILITIES F2:ANALYZE F3:CONFIGURATION F4:DEVICE MEMORY A. If the Bus Interface Unit is the current-selected device, press either F3 (Configuration) or F2 (analyze) twice. B.
7 The first screen that appears is the Monitor screen for the first discrete input ( I ) reference. Indicates force is in effect Current state or value Reference being monitored I00001 < *0 > B Display mode: B binary H hex D decimal frc hex Changing the Reference Type Being Displayed Use the F1 ( < ) key to select a reference type: I (discrete inputs), Q (discrete outputs), AQ (analog outputs), or AI (analog inputs).
7 Forcing/Unforcing the Displayed Reference Individual I/O points can be forced and unforced from the Hand-held Monitor (the HHM's circuit forcing capability must be enabled to use this function). Forcing an I/O point changes its state in the Bus Interface Unit's EEPROM memory. If the circuit is an output, the physical state of the output also changes. If the circuit is an input, the forced input data is sent to the CPU. Once forced, a circuit retains the forced state or value if power is removed.
7 Monitor/Control I/O Data: Series 90 PLC If the host is a Series 90 PLC, I/O data can be displayed in the PLC's reference tables. The PLC's reference tables displays will include those portions of the PLC's I, Q, AI, and AQ memory being used by a Bus Interface Unit. In the reference tables for the PLC, these inputs are displayed along with other system inputs. When the programmer is attached to the PLC, the programmer software can override or toggle the I/O data and cause a change.
7 Monitor/Control I/O Data: Computer To utilize the Bus Interface Unit's I/O data correctly, a computer must know the sequence of modules in the station, and the amount of input and output data each has. For the PCIM, QBIM, and other GENI-based interfaces, the input and output data will occupy the Device Input and Output Tables at the segments associated with the serial bus address of the Bus Interface Unit.
Chapter Datagrams 8 This chapter lists datagrams that can be sent to a Bus Interface Unit, and shows the datagrams for Field Control modules that are different from the formats used by other modules. It also shows the format of configuration data for the Bus Interface Unit and the modules in the station.
8 Datagram Types The table below shows the primary datagrams that may be acted upon by the Bus Interface Unit. The table lists the types of device that can send each datagram, and the resulting action taken by the Bus Interface Unit.
8 Read Map Subfunction Code: 2A hex This datagram is used to read the reference addresses and lengths that have been configured for the BIU’s network I/O map. Data Field Format: none Read Map Reply Subfunction Code: 2B hex A Bus Interface Unit sends this reply datagram after receiving a Read Map datagram. It contains the previously-configured BIU network map addresses. The BIU’s network map defines the BIU memory locations of the data that is exchanged on the bus.
8 Write Map Subfunction Code: 2C hex This datagram allows a CPU to change a previously-configured or unconfigured BIU network map addresses, if configuration is not currently protected. The BIU’s network map defines the BIU memory locations of the data that is exchanged on the bus. Starting references in I, AI, Q, and AQ memory are sent. If any length is zero, the associated starting reference is ignored; it is not meaningful. Byte No.
8 Report Fault Datagram Format The format of Report Fault datagrams sent by a Bus Interface Unit is shown below. The Series 90-70 Bus Controller interprets this information automatically; no datagram programming is required. If the host is a Series Six or Series Five PLC, this information is ignored. If the host is a computer, this information can be retrieved from the unsolicited datagram queue, and interpreted as needed for the application.
8 Fault Byte 3 byte 2 7 6 5 4 3 2 1 0 Fault record number (always 0) Number of fault records (always 1) Fault Bytes 4 and 5 Fault bytes 4 and 5 (bytes 3 and 4 of the datagram) identify the reference offset (within the Bus Interface Unit itself) assigned to the faulted module. This is an internal reference, not a Series 9070 reference.
8 Configuration Data BIU 0 1 2 3 4 For a Bus Interface Unit, the data format of configuration data transferred by Read Configuration Reply and Write Configuration datagrams is slightly different than the format for other Genius devices. Instead of an offset, the data specifies the slot number of a specific device in the Field Control Station.
8 Read Configuration Reply Data Subfunction Code: 03 hex This datagram is a reply to the Read Configuration datagram. The following pages show the formats of configuration data for Field Control devices. Byte # 0 1 2-N Description Slot (corresponds to slot supplied in Read Configuration message Length (depends on module type) Data format shown on the following pages Write Configuration Data Subfunction Code: 04 hex The Write Configuration datagram is used to send configuration data.
8 Write Configuration Datagram Format for Field Control Intelligent Modules When using the Write Configuration datagram to configure Group Moves, the datagram format is: Byte # 0 Description Slot number in bottom nibble, Intelligent Packet in upper nibble. Examples: 01(hex) writes packet 0 to intelligent module in slot 1 11(hex) writes packet 1 to intelligent module in slot 1. GFK-0825F 1 Length sent, in bytes (maximum per packet is 128) 2 (optional).

Set the other address selection bytes to all zeros.
8 Discrete Output Modules Configuration Data Format Specify the actual slot number and a length of 30. The reference address is the location in the BIU's I, Q, AI, or AQ memory that is used by the module's data. Specify only one address, typically in the discrete output (Q) table. Set the other address selection bytes to all zeros.
8 Discrete Combination Input/Output Modules Configuration Data Format Specify the actual slot number and a length of 20. Entering the Reference Addresses The reference addresses are the locations in the BIU's I, Q, AI, or AQ memory used by the module's data. In this module configuration only, the input reference is the first non-zero entry WITHOUT the corresponding bit set in byte 12 (see below) The output reference is the first non-zero entry WITH the corresponding bit set.
8 Conventional Analog Input Modules Configuration Data Format Specify the actual slot number and a length of 126. The reference address is the location in the BIU's I, Q, AI, or AQ memory that is used by the module's data. Specify only one address, typically in the analog input (AI) table.

Set the other address selection bytes to all zeros.
8 Bytes 14 - 61: Channel Configuration (Byte #) GFK-0825F Byte Description (Byte #) Byte Description 14 Input 1: circuit configuration (see above) 38 Input 3: circuit configuration (see above) 15 reserved 39 reserved 16, 17 low scaling point, eng. units (lsb in byte 16) 40, 41 low scaling point, eng. units (lsb in byte 40) 18, 19 high scaling point, eng. units (lsb in byte 18) 42, 43 high scaling point, eng.
8 Intelligent Modules Configuration Data Format Configuration files of intelligent modules may exceed the 128-byte maximum length of a Genius message. Therefore, any Write Configuration to an intelligent module must be contained within a Begin/End Packet Sequence. The BIU rejects any Write Configuration message for an intelligent module that does not follow a Begin Packet message.

Byte No. Byte Description 0 Mode 1 Mode This message has two copies of the mode parameter. These copies must be equal for the command to be accepted by the Bus Interface Unit. If you disable the network, the BIU sends no inputs and receives no outputs.
8 Intelligent Analog Module Recalibration Datagram Subfunction Code: 21 hex This datagram can be used to recalibrate a 16 Point Analog Grouped module (IC670ALG240), to restore the factory calibration, or to place the module into “warmup” mode for recalibration.
8 Field Recalibration The 16 Point Grouped Analog Input module is calibrated at the factory. It can also be recalibrated from the host, to adapt to different conditions. Calibration data consists of two sets of values for each channel. One value is provided to the module during calibration. The other value is a corresponding A/D sample value for that current that is determined by the module. One pair of values represents a low value (typically 4mA) and the other represents a high value (typically 20mA).
8 Read I/O Forces Subfunction Code: 40 hex This datagram can be used to set read force information from a Genius Bus Interface Unit. The information read is determined by the value specified in the datagram. Byte # Description 0 Force Table Requested: 0 = input enable 1 = output enable 2 = input values 3 = output values To read which inputs are forced, specify the number 0 in the datagram. To read which outputs are forced, specify 1 in the datagram.
8 Read Slot Diagnostics Subfunction Code: 42 hex This datagram can be used to read diagnostics information for a specific slot, point, or channel from a BIU. This message does not provide channel or point information for intelligent modules (which includes certain types of I/O modules and Micro Field Processors). Intelligent modules can be configured to provide the information automatically.
Appendix Scaling Analog Channels A This appendix explains how to select scaling values when configuring an analog input or output. See chapter 5 for configuration instructions. How Scaling Works Analog modules convert between electrical signals (current or voltage) and digital values. These digital values are 0 to 4095 (for 12-bit converters). Digital values are often referred to as “counts” They represent the data that is transferred between the Bus Interface Unit and an analog module.
A Scaling Values for 1mV or 1µA Engineering Units: BIU Version 1.3 For many applications, the engineering units are either millivolts or microAmps. These units are easy to scale. Simply use the table below to find scaling values that are appropriate for the channel's configured range.
A Scaling Values for 1mV or 1µA Engineering Units: BIU Version 2.0 or Later For many applications, the engineering units are either millivolts or microAmps. These units are easy to scale. Simply use the table below to find scaling values that are appropriate for the channel's configured range.
A Measuring Scaling Values If the circuit will not use millivolt or microAmp units, the most accurate scaling values can be found by taking actual measurements of the process. The process must be set to two distinctly different conditions, so two sets of measurements can be taken. If the analog module is already installed, you can use it online to the process being measured to obtain actual data values. By default, the Bus Interface Unit performs a 1 to 1 scaling on all channels.
A Example of Scaling an Analog Input A channel is configured in the 0 to 10 volts DC range. It measures a velocity input. Electronic sensors and mechanical linkage external to the block have determined that an input level of +1.5 volts DC is equal to -20 feet/second (-6 meters/second), and that +9 volts DC is equal to +180 feet/second (+50 meters/second). Plotting these values on a graph shows that a signal of 5 volts DC corresponds to a speed of 73.3 feet/second. 46746 Velocity 200 (+9.
Appendix Installing Additional Suppression B This appendix describes some precautions that can be taken in an installation to help assure proper operation. It is possible some installations might exceed the surge immunity capabilities specified in chapter 1. This is most likely in outdoor installations or where the power source is from another building or ground system. It is prudent to provide local transient protection.
B Suppression for Devices in an Enclosure For a group of devices installed in an enclosure, the MOVs can be installed at the point where the power lines enter the enclosure. Ideally, MOVs should be used at each cabinet in the system for maximum protection. The following illustration shows suppression on both power lines and the communications bus for modules in an enclosure.
Appendix The Genius Serial Bus C This appendix describes the selection and operating characteristics of the bus cable that links Genius devices. This information supercedes the equivalent text portion of chapter 2 of The Genius I/O System and Communications Manual (GFK-90486), “The Communications Bus”. A Genius serial bus consists of two or more Genius devices, and (usually) the bus cable that connects them.
C Electrical Interface The Genius serial bus uses computer grade twisted pair data cable. The half duplex token sequence used requires only a single pair since at any time only one station is transmitting and all others are receiving. All stations must receive in order to track the present token value and take their appropriate turn on the bus, regardless whether the data is to be used locally. The transmit sequence is the same as the serial bus address (SBA) set into each location during configuration.
C Genius Transceiver Electrical Specification Property Min Max Normal peak voltage Vp into 78 ohm terminated cable (1) 3.5 volts 5.5 volts Normal peak voltage Vp into 150 ohm terminated cable (1) 6.0 volts 9.
C Selecting a Cable Type The Genius bus is a shielded twisted-pair wire, daisy-chained from block to block and terminated at both ends. Proper cable selection is critical to successful operation of the system. Each bus in the system can be any cable type listed in the table below. Do not mix cables of different impedance, regardless of cable run length. Do not mix cable types in long and/or noisy installations.
C Serial Bus Waveforms The actual waveforms seen on the cable depend on the cable impedance and the distance from the station presently transmitting. A data “0” is a series of three AC pulses, while a “1”is no pulse. +Vp +Vr -Vr -Vp “0” “1” 1 t= baud rate “0” “0” “1” SERIAL 1 VOLTAGE RELATIVE TO SERIAL 2 Use caution when connecting instrumentation to the bus. A differential probe or a summation of two probes relative to ground is required.
C Using Other Cable Types The cable types listed in the preceding table are recommended for use. If the cable types listed above are not available, the cable selected must meet the following guidelines. 1. High quality construction. Most important is uniformity of cross section along the length of the cable. Poor quality cable may cause signal distortion, and increase the possibility of damage during installation. 2.
C Effect of Long Cables, Repeaters, or Unspecified Cable Types On Maximum Length Bus Three effects limit the maximum length bus available at any baud rate: 1. Voltage attenuation 2. Waveform distortion (frequency dispersion) 3. Propagation delays Attenuation The transmitter output levels and receiver thresholds determine the maximum attenuation that can be tolerated. For Genius products, this is the principal determinant when using recommended cable types.
C The half cycle pulse width, when measured between the positive and negative receiver thresholds, denoted as Tp/2 in the figure, will vary along the waveform due to dispersion, and resembles a frequency shift.. The digital input filter essentially is a band pass filter which looks at the half cycle timing Tp/2, and the duration above the thresholds, Tw. The limits are: • Tp/2 = 0.6 Tp(normal) maximum • Tw = 0.
C Bus Access All devices must receive the current SBA and the stop character even though the data is irrelevant locally. After the stop control character is received, each device on the bus starts a timer. The time delay is equal to a “skip time” times the difference between the device Serial Bus Address (SBA) and the last SBA received. The device will transmit after the time delay if no other start bits are detected first. Thus each device takes turn in order of SBA.
C Bus Length The maximum bus length for shielded, twisted-pair cable is 7500 feet. Some cable types are restricted to shorter bus lengths. In turn, the bus length determines which baud rate may be selected. If the application requires greater bus length, fiber optics cable and modems can be used, as explained later in this chapter.
C Bus Ambient Electrical Information Most capacitively- and magnetically-coupled noise shows up as common mode voltage on the bus. The bus provides a 60 dB common mode rejection ratio. A noise spike above 1000 volts would be required to corrupt the data. The bus receivers filter out corrupted data and perform a 6-bit cyclic redundancy check to reject bad data. Corrupted signals due to noise show up as missed data rather than incorrect data.
Appendix Configuration Examples D This appendix includes examples of different Field Control I/O Station configurations: • An I/O Station with discrete data only, where all of the data is configured within the BIU's I/O map. The BIU sends all inputs from Field Control modules on the network. All outputs are generated by the system controller (for example, a PLC) that sends them to the BIU over the network.
D Example 2: Discrete and Analog Data, Network Processing In this I/O Station, there are both discrete and analog I/O modules. All data is included within the I/O map that is configured for the Bus Interface Module, and exchanged over the network. There is no local Micro Field Processor. BIU Map: I00001 - I00112 Q00001 - Q00040 AI00001 - AI00024 AQ00001 - AQ00004 No synchronization is required.
D Example 3: Discrete and Analog Data, Network and Local Processing In this I/O Station, there are discrete and analog I/O modules and a Micro Field Processor. All inputs are given to the Micro Field Processor and processed. All outputs solved by the Micro Field Processor drive the station outputs. All inputs from the station are sent back the the system controller as well.
D Example 4: Discrete and Analog Data, Network and Local Processing and Group Data Moves In this I/O Station, there are discrete and analog I/O modules and a Micro Field Processor. Group Data Moves are used to transfer data within the I/O Station. This configuration allows all station inputs to be solved by the Micro Field Processor and all station outputs to be controlled by the Micro Field Processor. The system controller (for example, a PLC) will receive all station inputs.
D Group Move #3: Source slot 3, Destination slot 0 (move RTD inputs to BIU input tables). All submoves can be set to default to either Yes or No. Submove 1: Submove 2: (Moves diagnostic bits) Source reference I00001 Destination reference I00089 Length 4 bytes (moves analog inputs) Source reference AI00001 Destination reference AI00017 Length 8 bytes Group Move #4: Source slot 0, Destination slot 3 (move control outputs from BIU tables to RTD module).
D Example 5: Group Move A Field Control Station has a Genius BIU in slot 0, a Micro Field Processor in slot 1, and a Smart analog input module in slot 2. In this example, two group moves are used to transfer the following data: • Slot 0 Group 1: from the Smart Analog Input Module to the Micro Field Processor: The second byte of I data (which contains diagnostic status information about the module) is to be moved to MFP memory starting at I0017.
