Chapter 1 What Are ControlLogix Digital I/O Modules? I/O Modules in the ControlLogix System ControlLogix modules mount in a ControlLogix chassis and require either a removable terminal block (RTB) or a Bulletin 1492 wiring interface module (IFM)(1) to connect all field-side wiring. Before you install and use your module, you must do the following: • Install and ground a 1756 chassis and power supply. To install these products, refer to the publications listed in Additional Resources on page 12.

Chapter 2 Digital I/O Operation in the ControlLogix System Ownership I/O modules in a ControlLogix system can be owned by an RSLogix™ 5000 controller.
Digital I/O Operation in the ControlLogix System Chapter 2 Refer to the following general steps when configuring I/O modules. 1. Configure all I/O modules for a given controller by using RSLogix 5000 software and download that information to the controller. 2. If the I/O configuration data references a scheduled connection to a module in a remote chassis connected via the ControlNet network, run RSNetWorx for ControlNet software to schedule the network. 3.
Chapter 2 Digital I/O Operation in the ControlLogix System The table defines some of the delay factors that affect the signal propagation on an I/O module. Delay Description Hardware How the module is configured and the variance between the type of modules affects how the signal is processed. Filter User configuration varies between modules, thus affecting the signal propagation. ASIC ASIC scan = 200 μs.
Digital I/O Operation in the ControlLogix System Chapter 2 The table defines some of the delay factors that affect the signal propagation on an I/O module. Delay Description Hardware How the module is configured and the variance between the type of modules affects how the signal is processed. ASIC ASIC scan = 200 μs. EXAMPLE Connections A typical delay time can be estimated despite the number of factors that might contribute.
Chapter 2 Digital I/O Operation in the ControlLogix System Direct Connections A direct connection is a real-time data transfer link between the controller and the device that occupies the slot that the configuration data references. When module configuration data is downloaded to an owner-controller, the controller attempts to establish a direct connection to each of the modules referenced by the data.
Digital I/O Operation in the ControlLogix System IMPORTANT Chapter 2 Because rack-optimized connections are applicable only in applications that use a remote chassis, you must configure the communication format , as described in Chapter 7, for both the remote I/O module and the remote 1756-CNB module or EtherNet/IP module. Make sure you configure both modules for rack optimization.
Chapter 2 Digital I/O Operation in the ControlLogix System Suggestions for Rack-optimized Connections We recommend that you use a rack-optimized connection for these applications: • Standard digital I/O modules • Non-fused digital output modules • Owner-controllers running low on connections IMPORTANT Input Module Operation Rack-optimized connections are available only to digital I/O modules. However, do not use a rack-optimized connection for diagnostic I/O modules or fused output modules.
Digital I/O Operation in the ControlLogix System Chapter 2 When a module resides in the same chassis as the owner-controller, the following two configuration parameters affect how and when an input module multicasts data: • Requested packet interval (RPI) • Change of state (COS) Input Modules in a Local Chassis RPI The RPI defines the slowest rate at which a module multicasts its data to the owner-controller.
Chapter 2 Digital I/O Operation in the ControlLogix System Because the RPI and COS functions are asynchronous to the program scan, it is possible for an input to change state during program scan execution. The point must be buffered to prevent this from occurring. To buffer the point, you can copy the input data from your input tags to another structure and use the data from there.
Digital I/O Operation in the ControlLogix System Chapter 2 Remote Input Modules Connected via the ControlNet Network When an RPI value is specified for an input module in a remote chassis connected by a scheduled ControlNet network, in addition to instructing the module to multicast data within its own chassis, the RPI also reserves a spot in the stream of data flowing across the ControlNet network. The timing of this reserved spot may or may not coincide with the exact value of the RPI.
Chapter 2 Digital I/O Operation in the ControlLogix System Worst Case RPI Multicast Scenario In the worst case scenario, the module performs an RPI multicast just after the reserved network slot has passed. In this case, the owner-controller will not receive data until the next available network slot. Enabling the COS feature on an input module in a remote chassis allows the module to multicast data at both the RPI rate and when the input changes state. This helps to reduce the worst case time.
Digital I/O Operation in the ControlLogix System Output Module Operation Chapter 2 An owner-controller sends output data to an output module when either one of two things occur: • At the end of every one of its tasks (local chassis only) • At the rate specified in the module’s RPI When an output module physically resides in a remote chassis with respect to the owner-controller, the owner-controller sends data to the output module only at the RPI rate specified for the module.
Chapter 2 Digital I/O Operation in the ControlLogix System If an output module physically resides in a chassis other than that of the owner-controller, the owner-controller normally sends data to the output module at the RPI rate specified. Updates are not performed at the end of the controller’s tasks. Output Modules in a Remote Chassis In addition, the role of the RPI for a remote output module changes slightly with respect to getting data from the owner-controller.
Digital I/O Operation in the ControlLogix System Chapter 2 Worst Case RPI Multicast Scenario In the worst case scenario, the owner-controller sends the output data just after the reserved network slot has passed. In this case, the output module does not receive data until the next available network slot. IMPORTANT These best and worst case scenarios indicate the time required for output data to transfer from the owner-controller to the module once the owner-controller has produced it.
Chapter 2 Digital I/O Operation in the ControlLogix System Listen-only Mode Any controller in the system can listen to the data from any I/O module, such as input data, echoed output data, or echoed diagnostic information. Even if a controller does not own a module, or hold the module’s configuration data, the controller can still listen to the module. During the module configuration process, you can specify one of several Listen modes.
Digital I/O Operation in the ControlLogix System Chapter 2 As soon as a controller receives its user program, it will try to establish a connection with the input module. A connection is established with the controller whose configuration data arrives first. When the second controller’s configuration data arrives, the module compares it to its current configuration data, which was received and accepted from the first controller.
Chapter 2 Digital I/O Operation in the ControlLogix System To prevent other owner-controllers from receiving potentially erroneous data, use these steps when changing a module’s configuration in a multiple owner scenario while online. 1. For each owner-controller, inhibit the connection to the module either in the software on the Connection tab or the message dialog box warning you of the multiple owner condition. 2. Make the appropriate configuration data changes in the software.
Chapter 3 Common Module Features Input Module Compatibility Topic Page Input Module Compatibility 37 Output Module Compatibility 38 Common Features 39 Common Features Specific to Input Modules 50 Common Features Specific to Output Modules 54 Fault and Status Reporting between Input Modules and Controllers 64 Fault and Status Reporting between Output Modules and Controllers 65 ControlLogix digital input modules interface to sensing devices and detect whether they are On or Off.
Chapter 3 Common Module Features Output Module Compatibility ControlLogix output modules can be used to drive a variety of output devices. Typical output devices compatible with ControlLogix outputs include these items: • Motor starters • Solenoids • Indicators Follow these guidelines when designing a system: • Make sure that the ControlLogix outputs can supply the necessary surge and continuous current for proper operation. • Make sure that the surge and continuous current are not exceeded.
Common Module Features Common Features Chapter 3 The table below lists features common to all ControlLogix digital I/O modules.
Chapter 3 Common Module Features Software Configurable RSLogix 5000 software provides an interface to configure each module. All module features are enabled or disabled through the I/O configuration within the software.
Common Module Features Chapter 3 Electronic keying is based on a set of attributes unique to each product revision. When a Logix5000 controller begins communicating with a module, this set of keying attributes is considered. Attribute Description Vendor The manufacturer of the module, for example, Allen-Bradley. Product Type The general type of the module, for example, communication adapter, AC drive, or digital I/O.
Chapter 3 Common Module Features In the following scenario, Exact Match keying prevents I/O communication. The module configuration is for a 1756-IB16D module with module revision 3.1. The physical module is a 1756-IB16D module with module revision 3.2. In this case, communication is prevented because the Minor Revision of the module does not match precisely.
Common Module Features Chapter 3 When a module is created, the module developers consider the module’s development history to implement capabilities that emulate those of the previous module. However, the developers cannot know future developments. Because of this, when a system is configured, we recommend that you configure your module by using the earliest, that is, lowest, revision of the physical module that you believe will be used in the system.
Chapter 3 Common Module Features EXAMPLE In the following scenario, Compatible Keying allows I/O communication. The module configuration is for a 1756-IB16D module with module revision 2.1. The physical module is a 1756-IB16D module with module revision 3.2. In this case, communication is allowed because the major revision of the physical module is higher than expected and the module determines that it is compatible with the prior major revision.
Common Module Features EXAMPLE Chapter 3 In the following scenario, Disable Keying prevents I/O communication. The module configuration is for a 1756-IA16 digital input module. The physical module is a 1756-IF16 analog input module. In this case, communication is prevented because the analog module rejects the data formats that the digital module configuration requests.
Chapter 3 Common Module Features IMPORTANT Changing electronic keying selections online may cause the I/O communication connection to the module to be disrupted and may result in a loss of data. Module Inhibiting Module inhibiting lets you indefinitely suspend a connection between an owner-controller and a digital I/O module without having to remove the module from the configuration. This process lets you temporarily disable communication to a module, such as to perform maintenance.
Common Module Features Chapter 3 Use the System Clock to Timestamp Inputs and Schedule Outputs This section describes how to use CST timestamps in standard and diagnostic I/O modules and the CIP Sync timestamps in fast I/O modules. Use Coordinated System Time with Standard and Diagnostic I/O Modules Time masters generate a 64-bit coordinated system time (CST) for their respective chassis.
Chapter 3 Common Module Features Use CIP Sync Time with Fast I/O Modules The 1756-IB16IF, 1756-OB16IEF, and 1756-OB16IEFS modules use CIP Sync for both timestamps and scheduling. CIP Sync is a CIP implementation of the IEEE 1588 PTP (Precision Time Protocol). CIP Sync provides accurate real-time (Real-World Time) or Universal Coordinated Time (UTC) synchronization of controllers and devices connected over CIP networks.
Common Module Features Chapter 3 Mixing CST and CIP Sync Modules in a ControlLogix System CST is automatically enabled for each chassis that has been configured to use CIP Sync. Therefore, it is possible to include modules that use CST for their time base into systems that have been configured to use CIP Sync. Also, there is a direct correlation between CIP Sync system time and the local chassis CST time.
Chapter 3 Common Module Features Producer/Consumer Communication By using Producer/Consumer communication, ControlLogix I/O modules can produce data without first being polled by a controller. The modules produce the data and any other owner-controller device can decide to consume it. For example, an input module produces data and any number of processors can consume the data at the same time. This eliminates the need for one processor to send the data to another processor.
Common Module Features Chapter 3 Data Transfer on Either Cyclic Time or Change of State Digital input modules always send data at the RPI, but they send data at a change of state only if the COS feature is enabled. COS is more efficient than RPI because it multicasts data only when a change occurs. The table describes the two ways a module sends data to the owner-controller. Method Description RPI A user-defined rate at which the module updates the information sent to its owner-controller.
Chapter 3 Common Module Features Enable Change of State The Point column on the left side of the Configuration tab lets you set whether a COS occurs when a field device transitions from Off to On or On to Off. Follow these steps to enable or disable COS. 1. On the Module Properties dialog box, click the Configuration tab. 2. Do one of the following in the Enable Change of State columns: • To enable COS for a point, check the corresponding Off to On or On to Off checkbox.
Common Module Features Chapter 3 Software Configurable Filter Times On to Off and Off to On filter times can be adjusted through RSLogix 5000 software for all ControlLogix input modules. These filters improve noise immunity within a signal. A larger filter value affects the length of delay times for signals from these modules. IMPORTANT Input filters on the 1756-IB16IF module function differently than other digital I/O modules. For information about input filters on the 1756-IB16IF module, see page 90.
Chapter 3 Common Module Features Multiple Input Point Densities ControlLogix input modules use either 8-, 16-, or 32-point densities for greater flexibility in your application. A point is the termination where a wire attaches to the input module from a field device. The module receives information from the device to this designated point, thus signaling when activity occurs. Common Features Specific to Output Modules 54 The table below lists features specific to ControlLogix digital output modules.
Common Module Features Chapter 3 Configurable Point-level Output States Individual outputs can be configured to unique output states if the module goes into Program mode or Fault mode. IMPORTANT Whenever you inhibit an output module, it enters Program mode, and all outputs change to the state configured for Program mode. For example, if an output module is configured so that the state of outputs turn Off during Program mode, whenever that module is inhibited, outputs turn Off.
Chapter 3 Common Module Features Output Data Echo During normal operation, when a controller sends out an output command to the ControlLogix system, the output module that is targeted for that command returns the commanded state of the output to the system. This process verifies that the module has received the command and will try to execute it.
Common Module Features Chapter 3 Multiple Output Point Densities ControlLogix output modules use either 8-, 16-, or 32-point densities for greater flexibility in your application. A point is the termination where a wire attaches to the I/O module from a device. The I/O gets information from the device to this designated point, thus signaling when activity occurs.
Chapter 3 Common Module Features Table 3 - Recommended Fuses (continued) Circuit Type DC Cat. No.
Common Module Features Chapter 3 You can reset an electronic fuse through RSLogix 5000 software during online monitoring or through program logic running on a controller. If your module uses point-level fusing, you can reset a fuse with a CIP Generic Message instruction, as described on page 227. Follow these steps to reset an electronic fuse through RSLogix5000 software during online monitoring. 1. On the Module Properties dialog box, click the Diagnostics tab.
Chapter 3 Common Module Features Field Power Loss Detection For the standard digital output modules, the Field Power Loss detection feature is found on the 1756-OA8E module only. When field power to the module is lost, or zero cross cannot be detected, a point-level fault is sent to the controller to identify the exact point faulted. IMPORTANT Only enable Field Power Loss detection for points that are in use.
Common Module Features Chapter 3 Diagnostic Latch of Information The diagnostic latch feature is available for the 1756-OA8E modules only. Diagnostic latching allows this module to latch a fault in the set position once it has been triggered, even if the error condition causing the fault to occur disappears. Follow these steps to enable diagnostic latch of information. 1. On the Module Properties dialog box, click the Configuration tab. 2. Do one of the following in Enable Diag.
Chapter 3 Common Module Features Latched diagnostic features can be cleared by using these methods: • Reset Diagnostic Latch service • Software reset during online monitoring • Cycling power to the module’s Follow these steps to a reset a latched fault through RSLogix 5000 software during online monitoring. 1. On the Modules Properties screen, click the Diagnostics tab. 2. In the Reset Latched Diagnostics column, click Reset next to the output point for which to reset a latched fault. 3. Click OK.
Common Module Features Chapter 3 Time-scheduled Output Control Time-scheduled output control is available for these modules: • 1756-OB16IS—Provides time-scheduled output control in CST time for outputs 0…7. Allows for schedules with a minimum interval of 100 μs. • 1756-OB16IEFS—Provides time-scheduled output control in CIP Sync time for outputs 0…15. Allows for schedules with a minimum interval of 5 μs.
Chapter 3 Common Module Features Use the Module Properties dialog box in RSLogix 5000 software to determine if the module has been synchronized with the owner-controller and whether the controller is synchronized with the CST. For more information on synchronizing owner-controllers and modules with the CST, see the ControlLogix System User Manual, publication 1756-UM001.
Common Module Features Fault and Status Reporting between Output Modules and Controllers Chapter 3 ControlLogix digital output modules multicast fault and status data to any owner-controller or listening controller. Like input modules, output modules maintain a module-fault word, the highest level of fault reporting. However, some output modules use additional words to indicate fault conditions.
Chapter 3 Common Module Features The following illustration offers an overview of the fault reporting process on ControlLogix digital output modules. Bit 31 Bit 0 Module-fault Word All modules 1 1 A communications fault sets all bits in the module-fault word. A fuse blown or field power loss condition sets the appropriate bits in the module-fault word.

Chapter 4 Diagnostic Module Features Diagnostic Output Module Compatibility ControlLogix diagnostic output modules are capable of directly driving the ControlLogix diagnostic digital inputs. When diagnostics are used, a shunt resistor is required for leakage current. For more information on the compatibility of motor starters with ControlLogix output modules, see Appendix E. Diagnostic Features The table below lists features common to all ControlLogix diagnostic digital I/O modules.
Diagnostic Module Features Chapter 4 2. Do one of the following in the Enable Diag. Latching column: • To enable diagnostic latching for a specific point, check the corresponding checkbox. • To disable diagnostic latching for a specific point, clear the corresponding checkbox. 3. Click OK.
Chapter 4 Diagnostic Module Features 8-Point AC/16-Point DC Diagnostic I/O modules provide various grouping of points on different modules. The eight-point AC modules and 16-point DC modules provide additional flexibility when designing module applications. The greater number of points allows for more field devices to be attached to I/O modules to boost efficiency. Point-level Fault Reporting Diagnostic I/O modules set bits to indicate when a fault has occurred on a point-by-point basis.
Diagnostic Module Features Chapter 4 The following table lists possible diagnostic faults on the 1756-OB16D module. Table 10 - 1756-OB16D Point-level Fault Scenarios Ladder commands output to be On Ladder commands output to be Off 1. Output Data Echo returns the state of the output as Off. 2. Fuse Blown bit is set.(1) 1. Output Data Echo returns the state of the output as Off.(4) Output is shorted to GND. 2. Pulse Test fails.(5) 1. Output Data Echo returns the state of the output as On. 2.
Chapter 4 Diagnostic Module Features Although the RPI occurs continuously, the COS feature lets you to decide whether changes in a module’s diagnostic detection should cause the module to send real-time data to the owner-controller. 1. On the Module Properties dialog box, click the Configuration tab. 2.
Diagnostic Module Features Chapter 4 Open Wire Detection Open Wire is used to verify the field wiring is connected to the module. The field device must provide a minimum leakage current to function properly. A leakage resistor must be placed across the contacts of an input device. The resulting current is then expected to exist when the input is open. For more information, see each module’s specifications in Chapter 8.
Chapter 4 Diagnostic Module Features Field Power Loss Detection For the standard digital output modules, the Field Power Loss detection feature is found on the 1756-IA8D module only. When field power to the module is lost, or zero cross cannot be detected, a point-level fault is sent to the controller to identify the exact point faulted. IMPORTANT Only enable Field Power Loss detection for points that are in use.
Diagnostic Module Features Features Specific to Diagnostic Output Modules Chapter 4 The table below lists features specific to ControlLogix diagnostic digital output modules. Topic Page Field Wiring Options 75 No Load Detection 75 Field-side Output Verification 76 Pulse Test 78 Diagnostic Change of State for Output Modules 79 Field Wiring Options As with diagnostic input modules, ControlLogix diagnostic output modules provide isolated or nonisolated wiring options.
Chapter 4 Diagnostic Module Features Diagnostic output modules list a minimum load current specification (1756-OA8D = 10 mA & 1756-OB16D = 3 mA). In the On state, the module must be connected to a load that will draw a minimum current equal to these values. If a connected load is sized in accordance with the minimum load current specification, diagnostic output modules are capable of sensing current through the optoisolator and the load when the output point is Off.
Diagnostic Module Features Chapter 4 This feature has a corresponding tag that can be examined in the user program in the event of a fault. For more information on these tags, see Appendix B. If an output cannot be verified, a point-level fault is sent to the controller. Follow these steps to enable the field-side output verification. 1. On the Module Properties dialog box, click the Configuration tab. 2.
Chapter 4 Diagnostic Module Features Pulse Test Pulse test is a feature found on diagnostic output modules that can verify outputcircuit functionality without actually changing the state of the output load device. A short pulse is sent to the targeted output circuit. The circuit should respond as it would if a real change-of-state command was issued, but the load device does not transition. See page 227 in Appendix C for instructions on performing a pulse test with a CIP Generic Message instruction.
Diagnostic Module Features Chapter 4 Diagnostic Change of State for Output Modules If the Diagnostic Change of State feature is enabled, a diagnostic output module sends new data to the owner-controller when one of the events described in the table occurs. Table 11 - Diagnostic Change of State Events Event Description Receipt of output data Output module sends data when it echoes back to the owner-controller.
Chapter 4 Diagnostic Module Features Fault bits in the field-power loss word and open wire word are logically entered into the module-fault word. Depending on the module type, a bit set in the module-fault word can mean multiple things, as indicated in the table. Table 13 - Bits Set in Module-fault Word Condition Bits Set Communications fault All 32 bits are set to 1, regardless of the module’s density. Field-power loss Open wire Only the bit affected is set to 1.
Diagnostic Module Features Fault and Status Reporting between Output Modules and Controllers Chapter 4 ControlLogix diagnostic digital output modules multicast fault and status data to any owner-controller or listening controller. Like input modules, output modules maintain a module-fault word, the highest level of fault reporting. However, some output modules use additional words to indicate fault conditions.
Chapter 4 Diagnostic Module Features The following illustration provides an overview of the fault reporting process for digital output modules. Bit 31 Bit 0 Module-fault Word 1 1 1 1 A communications fault sets all bits in the module-fault word. A fuse blown, field-power loss, no load or output verify condition sets the appropriate bit in the module-fault word.

Chapter 5 Fast Module Features Fast Output Module Compatibility ControlLogix fast output modules can be used to drive a variety of output devices. Typical output devices compatible with ControlLogix outputs include these items: • Solenoids • Indicators Follow these guidelines when designing a system: • Make sure that the ControlLogix outputs can supply the necessary surge and continuous current for proper operation. • Make sure that the surge and continuous current are not exceeded.
Fast Module Features Chapter 5 Response Time The tables below indicate the screw-to-backplane response time of fast input and fast output modules.
Chapter 5 Fast Module Features Pulse Capture The 1756-IB16IF fast input module can be used to detect or latch short duration pulses. The module can detect incoming pulses with a duration as short as 10 μs if the frequency is under 4 kHz (period of 250 μs). When the module detects a short duration pulse at an input point, it sets the corresponding bit for the Pt[x].NewDataOffOn or Pt[x].NewDataOnOff input tag. This bit remains latched until acknowledged.
Fast Module Features Chapter 5 Per Point Timestamping and Change of State With per point timestamping, each input point on the module records timestamps in CIP Sync format at these speeds: • ± 4 μs for inputs < 4 kHz • ± 13 μs for inputs > 4 kHz IMPORTANT Timestamping functions only in a CIP Sync system. If you are using change of state (COS) in a system using Coordinated System Time (CST), all timestamp values and the GrandMasterClockID input tag are set to zero.
Chapter 5 Fast Module Features Follow these steps to configure per point timestamping and enable COS. 1. On the New Module dialog box, click Change to display the Module Definition dialog box. Opens the Module Definition dialog box. 2. Use the table below to choose a connection format and input data type from the Connection and Input Data pull-down menus. IMPORTANT To enable timestamping, choose Timestamp Data as the input data type.
Fast Module Features Chapter 5 3. On the New Module or Module Properties dialog box, click the Configuration tab. Timestamp fields only appear on the Configuration tab when you choose Timestamp Data from the Input Data pull-down menu on the Module Definition dialog box. 4. Complete the fields as described in the table below and click OK.
Chapter 5 Fast Module Features Software Configurable Filter Times To account for hard contact bounce, you can configure Off to On and On to Off input filter times of 0…30, 000 μs in RSLogix 5000 software. These filters define how long an input transition must remain in the new state before the module considers the transition valid. When an input transition occurs, the module timestamps the transition on the edge of the transition and stores timestamp data for the transition.
Fast Module Features Chapter 5 Figure 9 - Valid Transition with No Bounce Input remains On for at least 2 ms. The transition is considered valid, and the timestamp is sent to the controller. Input turns On, and a timestamp is recorded. 0 1 2 3 4 5 6 7 8 Time in milliseconds Figure 10 - Transition Valid with Bounce Input turns On and remains On for at least 2 ms in the 20 ms time period that is 10x the input filter time.
Chapter 5 Fast Module Features Follow these steps to configure input filter times. 1. On the Module Properties dialog box, click the Configuration tab. 2. In the Input Filter Time column, enter Off to On and On to Off input filter times from 0…30,000 μs and click OK. 3. Complete the fields as described in the table below and click OK. 92 Field Description Configuration Tag Enable Filter To enable filtering for a point, check the corresponding checkbox.
Fast Module Features Chapter 5 Dedicated Connection for Event Tasks The 1756-IB16IF input module can initiate an event task over a dedicated second connection in response to four user-defined input patterns. You can define these patterns in real time during a control process by using these output tags: • Event[x].Mask—Defines which input points trigger the event task. • Event[x].Value—Defines whether the masked input points must be in the On or Off state before the event task is triggered.
Chapter 5 Fast Module Features In example pattern 4, the input module triggers the event task when input points 0…3 are in the On state, and input points 12…15 are in the Off state. Table 21 - Example Pattern 4 Output Tag Bit Position 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Event[x].Mask 1 1 1 1 0 0 0 0 0 0 0 0 1 1 1 1 Event[x].

Chapter 5 Fast Module Features For more information about defining a Fault mode state, refer to Configurable Point-level Output States on page 55. Follow these steps to configure a fault state delay. 1. On the Module Properties dialog box, click the Output State tab. 2. Complete the fields as described in the table below and click OK.
Fast Module Features Chapter 5 Pulse Width Modulation Pulse Width Modulation (PWM) provides precise, onboard control of an output’s pulse train with no program variability. To configure a PWM signal, you define two real-time values for the pulse train in the module’s output tags: • Cycle time—The duration of a pulse cycle in seconds from 1 ms…1 hour. • On time—The pulse width, or length of time that a pulse is active within a cycle from 200 μs…1 hour.
Chapter 5 Fast Module Features Figure 13 compares two applications in which the output is instructed to turn On for 4.5 seconds: • In the application without PWM, a single pulse is generated. The pulse remains active for the same length of time the Data output tag is On (4.5 seconds). • In the application with PWM, a series of pulses are generated. Each pulse is active for a configured On time of .5 seconds or 50% of the 1 second cycle time. The Data output tag is On for 4.5 seconds.
Fast Module Features IMPORTANT Chapter 5 The Program and Fault mode states configured for the module override the PWM output state unless the point is configured to hold the last state while in Program or Fault mode. If a point is configured to hold the last state and the output is currently On, the output will continue to use PWM until the PWM cycle limit is reached, the module transitions out of Program or Fault mode, or a final fault state goes into effect.
Chapter 5 Fast Module Features If the output logic turns Off before the cycle limit is reached, you can configure the pulse cycles to continue until the cycle limit is reached by enabling the Execute All Cycles option. Figure 16 shows a cycle limit of 2 with the Execute All Cycles option enabled. Figure 16 - PWM Cycle Limit with Execute All Cycles Option Output Logic Output State Both cycles are executed even though the output logic turned Off before the cycle limit was reached.
Fast Module Features Chapter 5 In this type of application, the Minimum On Time, Extend Cycle, and Stagger Output configuration options provide these benefits: • Minimum On Time and Extend Cycle—Ensures that output devices that require a minimum time to turn On or that cannot react to a short pulse cycle can react with any given PWM On time calculation rather than not turning On.

Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration Topic Page Using Message Instructions 213 Processing Real-time Control and Module Services 214 One Service Performed Per Instruction 214 Create a New Tag 214 You can use ladder logic to perform run-time services on your module. For example, page 59 shows how to reset an electronic fuse module by using RSLogix 5000 software.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration Processing Real-time Control and Module Services Services sent through message instructions are not as time critical as the module behavior defined during configuration and maintained by a real-time connection. Therefore, the module processes messaging services only after the needs of the I/ O connection have been met.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C A graphic that looks like a ladder, with rungs, appears in the right side of the RSLogix 5000 software program. You attach run-time service, such as a message instruction, to the rungs and then download the information to a controller. You can tell that the rung is in Edit mode because of the ‘e’ at the left side of the rung. 3. Find, then click MSG (message) instruction on the instruction toolbar.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration 5. Choose New Tag. The New Tag dialog box appears with the cursor in the Name field. IMPORTANT We suggest you name the tag to indicate what module service the message instruction is sending. For example, if a message instruction is to reset an electronic fuse, then name the tag, ‘reset fuse’, to reflect this. 6. Complete the fields on the New Tag dialog box.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C Enter Message Configuration After creating a tag, you must enter certain parameters for the message configuration. This information is entered on the Configuration and Communication tabs of the Message Configuration dialog box. The Message Configuration dialog box is accessed by clicking the box with the ellipses (in the Message Control field). IMPORTANT In RSLogix 5000 software, version 10.07.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration Configuration Tab The Configuration tab provides information on what module service to perform and where to perform it. RSLogix 5000 Software, Version 9.00.00 or Earlier RSLogix 5000 Software, Version 10.07.00 or Later The following table explains the relationship of the fields in the above dialog boxes.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C The following table contains code information that is necessary only if you are configuring the message with RSLogix 5000 software, version 9.00.00 or earlier. Table 57 - Module Services and Configuration Information—Required for RSLogix 5000 Software, Version 9.00.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration Table 58 - Copy Instruction Parameters for Module Services—Required for RSLogix 5000 Software, Version 9.00.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C The following table lists tags used in the Source and Destination fields of the message instructions. Table 59 - Source and Destination Field Tags Source Tag Description Enable_32_Points DINT Parameter used to determine which points are enabled for the service. That is, if bit 0 = 1 for Reset Fuse, then point 0 has its electronic fuse reset. Results_32_Points DINT Pass (0)/ Fail (1) result for the service.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration Use Timestamped Inputs and Scheduled Outputs for Standard and Diagnostic I/O Modules This section demonstrates the use of timestamped inputs and scheduled outputs for standard and diagnostic digital I/O modules. The Change of State timestamp can be used to synchronize the output turning On or Off based on the time that the input transitions.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C • Rung 3 is the main rung that checks for Change of State on the input point by comparing the current input timestamp (Time_at_which_Input_Changed) with the last timestamp (LastTimestamp). The input point (point 0) must have Change of State enabled or the timestamp will not update when the point transitions. Once Change of State has been detected, 10 ms is added to the input timestamp and sent to the output module's timestamp.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration The only difference is the output module is configured for scheduled outputs. The outputs will not get applied until the scheduled time has occurred. The Controller Tags dialog box below shows examples of the tags created in ladder logic. Use Timestamped Inputs and Scheduled Outputs for Fast I/O Modules This section demonstrates the use of timestamped inputs and scheduled outputs for fast digital I/O modules.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C The following illustrations show the ladder instructions the program uses. The rungs perform these tasks: • Rungs 0 and 1 capture the rising or falling timestamps for input 0 of a 1756-IB16IF module. • Rung 2 executes only once at the transition from Program to Run mode.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration The input point (point 0) must have Change of State enabled. Otherwise, the timestamp will not update when the point transitions. Once Change of State has been detected, the value in the Delay tag is added to the input timestamp and sent to the output module's timestamp using a COP instruction. This causes the output module to apply its output at a time equal to the time that the input changed state plus the Delay time.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C Reset a Fuse, Perform Pulse Test and Reset Latched Diagnostics The following ladder logic program shows how to use ladder logic to reset an electronic fuse for a faulted point, perform a pulse test, and to reset latched diaganostics. Click the box in each rung to see the associated configuration and communication.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration The Controller Tags dialog box shows examples of the tags created in the ladder logic, as displayed in the tag editor. Perform a WHO to Retrieve Module Identification and Status This ladder logic example shows how to retrieve module identification and status through a WHO service.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C The user-defined WHO data structure displays module identification information in an easily understood format. For example, the Controller Tags dialog box shows the module’s major revision is 2. You do not have to create the user-defined data structure.
Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration The illustration shows an example WHO ladder logic application. The rungs perform these functions: • Rung 0 constantly polls the module for WHO status. To conserve bandwidth, only poll for status when necessary. • Rung 1 extracts the product type and catalog code. • Rung 2 extracts the module’s major and minor revisions. • Rung 3 extracts the module’s status information. • Rung 4 extracts the vendor ID and serial number.
Use Ladder Logic To Perform Run Time Services and Reconfiguration Appendix C The table defines the values returned for each rung.
