Introduction 1 At a Glance Introduction This chapter provides a general overview of the network interface module (NIM) and the Advantys STB island bus. The chapter concludes with an introduction to the specific features of the STB NIP 2212 Ethernet Modbus TCP/IP NIM.
Introduction What Is a Network Interface Module? Purpose Every island requires a network interface module (NIM) in the leftmost location of the primary segment. Physically, the NIM is the first (leftmost) module on the island bus. Functionally, it is the gateway to the island bus—all communications to and from the island bus pass through the NIM. The NIM also has an integrated power supply that provides logic power to the island modules.
Introduction Integrated Power Supply 890USE17700 September 2003 The NIM’s built-in 24-to-5 VDC power supply provides logic power to the I/O modules on the primary segment of the island bus. The power supply requires a 24 VDC external power source. It converts the 24 VDC to 5 V of logic power, providing 1.2 A of current to the island. Individual STB I/O modules in an island segment generally draw a current load of between 50 and 90 mA.
Introduction Structural Overview 14 The following figure illustrates the multiple roles of the NIM.
Introduction What Is Advantys STB? Introduction Advantys STB is an assembly of distributed I/O, power, and other modules that function together as an island node on an open fieldbus network. Advantys STB delivers a highly modular and versatile slice I/O solution for the manufacturing industry, with a migration path to the process industry. Advantys STB lets you design an island of distributed I/O where the I/O modules can be installed as close as possible to the mechanical field devices that they control.
Introduction Extension Segments Advantys STB I/O modules that do not reside in the primary segment can be installed in extension segments. Extension segments are optional segments that enable an island to be a truly distributed I/O system. The island bus can support as many as six extension segments. Special extension modules and extension cables are used to connect segments in a series.
Introduction Preferred Modules An island bus can also support those auto-addressable modules referred to as preferred modules. Preferred modules do not mount in segments, but they do count as part of the 32-module maximum system limit. Note: If you want to include preferred modules in your island, you need to configure the island using the Advantys configuration software.
Introduction Standard CANopen Devices You may also install one or more standard CANopen devices on an island. These devices are not auto-addressable, and they must be installed at the end of the island bus. If you want to install standard CANopen devices on an island, you need to use an STB XBE 2100 CANopen extension module as the last module in the last segment.
Introduction STB NIP 2212 Product Overview Introduction An Advantys STB island bus configured with an STB NIP 2212 network interface module (NIM) can function transparently as a node on an Ethernet local area network (LAN), or on the Internet. It can function, indirectly, as a node on a wide area network (WAN). Similarly to the other Advantys STB NIMs, the STB NIP 2212 can be a slave device. In the case of the STB NIP 2212, the manager is an Ethernet host.
Introduction Conformance to NIM Standards The STB NIP 2212 is designed to support all of the standard Advantys STB NIM features and functions (See What Is a Network Interface Module?, p. 12). Because an STB NIP 2212 runs Modbus as its fieldbus protocol, a device running the Advantys configuration software or a human-machine interface (HMI) can attach to either its fieldbus (Ethernet) port) (See STB NIP 2212 Network Interface, p. 26) or its CFG port (See The CFG Interface, p. 33).
Introduction Ethernet Communications and Connectivity Introduction The STB NIP 2212 allows the Advantys STB island to function as a node on an Ethernet local area network (LAN). Ethernet is an open local (communications) network that enables the interconnectivity of all levels of manufacturing operations from the plant’s office to the sensors and actuators on its floor. Conformance The STB NIP 2212 is located on a 10Base-T LAN. The 10Base-T standard is defined by the IEEE 802.3 Ethernet specification.

The STB NIP 2212 NIM The Power Supply Interface Introduction The NIM’s built-in power supply requires 24 VDC from an external SELV-rated power source. The connection between the 24 VDC source and the island is the male two-pin connector illustrated below.
The STB NIP 2212 NIM Connectors Use either: l a screw type power connector, available in a kit of 10 (model STB XTS 1120) l a spring clamp power connector, available in a kit of 10 (model STB XTS 2120) The following illustrations show two views of each power connector type.
The STB NIP 2212 NIM Logic Power Introduction Logic power is a 5 VDC power signal on the island bus that the I/O modules require for internal processing. The NIM has a built-in power supply that provides logic power. The NIM sends the 5 V logic power signal across the island bus to support the modules in the primary segment. External Source Power Input from an external 24 VDC power supply (See Characteristics of the External Power Supply, p.
The STB NIP 2212 NIM Logic Power Flow The figure below shows how the NIM’s integrated power supply generates logic power and sends it across the primary segment: 5V 24 V 24 VDC The figure below shows how the 24 VDC signal is distributed to an extension segment across the island: 5V 5V 24 V 24 V 24 VDC The logic power signal is terminated in the STB XBE 1000 module at the end of the segment (EOS). Island Bus Loads 38 The built-in power supply produces 1.2 A of current for the island bus.
The STB NIP 2212 NIM Selecting a Source Power Supply for the Island’s Logic Power Bus Logic Power Requirements An external 24 VDC power supply is needed as the source for logic power to the island bus. The external power supply connects to the island’s NIM. This external supply provides the 24 V input to the built-in 5 V power supply in the NIM. The NIM delivers the logic power signal to the primary segment only.
The STB NIP 2212 NIM Calculating the Wattage Requirement 40 The amount of power (See Logic Power Flow, p. 38) that the external power supply must deliver is a function of the number of modules and the number of built-in power supplies installed on the island. The external supply needs to provide 13 W of power for the NIM and 13 W for each additional STB power supply (like an STB XBE 1200 BOS module).
The STB NIP 2212 NIM The extended island bus contains three built-in power supplies: l the supply built into the NIM, which resides in the leftmost location of the primary segment l a power supply built into each of the STB XBE 1200 BOS extension modules, which reside in the leftmost location of the two extension segments In the figure, the external supply would provide 13 W of power for the NIM plus 13 W for each of the two BOS modules in the extension segments (for a total of 39 W).
The STB NIP 2212 NIM Module Specifications Specifications Detail The general specifications for the STB NIP 2212, which is the Ethernet network interface module (NIM) for an Advantys STB island bus, appear in the following table: General Specifications dimensions interface and connectors built-in power supply width 40.5 mm (1.594 in) height 130 mm (4.941 in) depth 70 mm (2.

Configuring the Island Bus 3 At a Glance Introduction The information in this chapter describes the auto-addressing and autoconfiguration processes. An Advantys STB system has an auto-configuration capability in which the current, actual assembly of I/O modules on the island bus is read every time that the island bus is either powered up or reset. This configuration data is saved to Flash memory automatically. The removable memory card is discussed in this chapter.
Configuring the Island Bus Auto-Addressing Introduction Each time that the island is powered up or reset, the NIM automatically assigns a unique island bus address to each module on the island that will engage in data exchange. All Advantys STB I/O modules and preferred devices engage in data exchange and require island bus addresses.
Configuring the Island Bus An Example For example, if you have an island bus with eight I/O modules: 1 NIM 2 STB PDT 3100 24 VDC power distribution module 3 STB DDI 3230 24 VDC two-channel digital input module 4 STB DDO 3200 24 VDC two-channel digital output module 5 STB DDI 3420 24 VDC four-channel digital input module 6 STB DDO 3410 24 VDC four-channel digital output module 7 STB DDI 3610 24 VDC six-channel digital input module 8 STB DDO 3600 24 VDC six-channel digital output module 9
Configuring the Island Bus Associating the Module Type with the Island Bus Location 48 As a result of the configuration process, the NIM automatically identifies physical locations on the island bus with specific I/O module types. This feature enables you to hot swap a failed module with a new module of the same type.
Configuring the Island Bus Auto-Configuration Introduction All Advantys STB I/O modules are shipped with a set of predefined parameters that allow an island to be operational as soon as it is initialized. This ability of island modules to operate with default parameters is known as auto-configuration. Once an island bus has been installed, assembled, and successfully parameterized and configured for your fieldbus network, you can begin using it as a node on that network.
Configuring the Island Bus Installing the STB XMP 4440 Optional Removable Memory Card Introduction The STB XMP 4440 removable memory card is a 32-kbyte subscriber identification module (SIM) that lets you store (See Saving Configuration Data, p. 164), distribute, and reuse custom island bus configurations. If the island is in unprotected (edit) mode (See Protection Feature, p.
Configuring the Island Bus Installing the Card Use the following procedure to install the card: Step 1 Action Punch out the removable memory card from the plastic card on which it is shipped. removable memory card Make sure that the edges of the card are smooth after you punch it out. 890USE17700 September 2003 2 Open the card drawer on the front of the NIM. If it makes it easier for you to work, you may pull the drawer completely out from the NIM housing.
Configuring the Island Bus Removing the Card Use the following procedure to remove the card from the card drawer. As a handling precaution, avoid touching the circuitry on the removable memory card during its removal. Step 52 Action 1 Open the card drawer. 2 Push the removable memory card out of the drawer through the round opening at the back. Use a soft but firm object like a pencil eraser.
Configuring the Island Bus Using the STB XMP 4440 Optional Removable Memory Card to Configure the Island Bus Introduction A removable memory card is read when an island is powered on. If the configuration data on the card is valid, the current configuration data in Flash memory is overwritten. A removable memory card can be active only if an island is in edit mode. If an island is in protected mode (See Protecting Configuration Data, p. 165), the card and its data are ignored.
Configuring the Island Bus Initial Configuration and Reconfiguration Scenarios Use the following procedure to set up an island bus with configuration data that was previously saved (See Saving Configuration Data, p. 164) to a removable memory card. You can use this procedure to configure a new island or to overwrite an existing configuration. Note: Using this procedure will destroy your existing configuration data.
Configuring the Island Bus The RST Button Summary The RST function is basically a Flash memory overwriting operation. This means that RST is functional only after the island has been successfully configured at least once. All RST functionality is performed with the RST button, which is enabled only in edit mode. Physical Description The RST button is located immediately above the CFG port (See Physical Description, p.
Configuring the Island Bus RST Functionality Introduction The RST function allows you to reconfigure the operating parameters and values of an island by overwriting the current configuration in Flash memory. RST functionality affects the configuration values associated with the I/O modules on the island, the operational mode of the island, and the CFG port parameters. The RST function is performed by holding down the RST button (See The RST Button, p. 55) for at least two seconds.
Configuring the Island Bus Overwriting Flash Memory with Factory Default Values The following procedure describes how to use the RST function to write default configuration data to Flash memory. Follow this procedure if you want to restore default settings to an island. This is also the procedure to use to update the configuration data in Flash memory after you add an I/O module to a previously auto-configured island bus.

Data Exchange 6 At a Glance Introduction This chapter describes how data stored in the process image is exchanged between the STB NIP 2212 and the Ethernet network, via Modbus over TCP/IP.
Data Exchange Data Exchange with the STB NIP 2212 Introduction Data exchange between a Modbus over TCP/IP host or the HTTP embedded web server and the Advantys STB island bus is conducted over the Ethernet port on the STB NIP 2212. Master Devices The input and output data image areas (See The Island’s Process Image Blocks, p. 169) can be accessed and monitored over the Ethernet LAN by a Modbus over TCP/IP fieldbus master or the STB NIP 2212 HTTP embedded web server.
Data Exchange Data and Status Objects Data exchange between the island and the fieldbus master involves three object types: l data objects, which are operating values that the master either reads from the input modules or writes to the output modules l status objects, which are module health records sent to the input area of the process image by all of the I/O modules and read by the master l echo output data objects, which the digital output modules send to the input process image; these objects are usua
Data Exchange The I/O modules have the following island bus addresses: I/O Model Module Type Module’s Island Bus Address STB DDI 3230 two-channel digital input N1 STB DDO 3200 two-channel digital output N2 STB DDI 3420 four-channel digital input N3 STB DDO 3410 four-channel digital output N4 STB DDI 3610 six-channel digital input N5 STB DDO 3600 six-channel digital output N6 STB AVI 1270 two-channel analog input N7 STB AVO 1250 two-channel analog output N8 The PDM and the termina
Data Exchange The Output Data Process Image The output data process image contains the data written to the island from the Modbus over TCP/IP host. This data is used to update the output modules on the island bus. In the sample island bus assembly, there are four output modules—three digital output modules and one analog output module. Each digital output module uses one Modbus register for its data. The analog output module requires two registers, one for each output channel.
Data Exchange The Input Data and I/O Status Process Image Input data and I/O status information from the I/O modules are sent to the input process image area. The fieldbus master or another monitoring device, e.g., an HMI panel (See The HMI Blocks in the Island Data Image, p. 172), can view data in the input data image area. All eight I/O modules are represented in the input process image area. Their assigned registers start at register 45392 and continue in the order of their island bus addresses.
Data Exchange In total, the Modbus over TCP/IP sample island bus requires 18 registers (registers 45392 through 45409) to support our configuration: register 45392 15 14 13 12 11 10 STB DDI 3230 data 9 8 7 6 5 4 3 2 1 0 ON/OFF conditions of inputs 1 and 2 always 0 register 45393 15 14 13 12 11 10 STB DDI 3230 status 9 8 7 6 5 4 3 2 1 0 presence/absence of PDM short always 0 STB DDO 3200 echo output data register 45394 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 echoes module outp

Data Exchange Reading Diagnostic Data Summary Thirty-five contiguous registers (45357 through 45391) in the island bus data image (See The Data Image, p. 167) are reserved for diagnostic data about the Advantys STB system. The diagnostic registers have pre-defined meanings, which are described below. Master Devices The diagnostic registers can be monitored by a Modbus over TCP/IP host or the STB NIP 2212 embedded web server. The master devices use Modbus messaging (See List of Supported Commands, p.
Data Exchange 1 The island is initializing. 2 The island has been set to pre-operational mode, for example, by the reset function. 3 The STB NIP 2212 is configuring or auto-configuring—communication to all modules is reset. 4 The STB NIP 2212 is configuring or auto-configuring—checking for any modules that are not auto-addressed. 5 The STB NIP 2212 is configuring or auto-configuring—Advantys STB and preferred modules are being auto-addressed.
Data Exchange Error Reporting Each bit in register 45358 indicates a specific global error condition. A value of 1 indicates an error: Register 45358 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 see 1 reserved see 2 see 12 see 3 reserved see 4 see 11 see 5 see 10 see 9 see 8 see 6 see 7 1 Fatal error. Because of the severity of the error, no further communications are possible on the island bus.
Data Exchange Node Configuration The next eight contiguous registers (registers 45359 through 45366) display locations where modules have been configured on the island bus. This information is stored in Flash memory. At start up, the actual locations of the modules on the island are validated by comparing them to the configured locations stored in memory. Each bit represents one configured location: l A value of 1 in a bit indicates that a module has been configured for the associated location.
Data Exchange Node Assembly The next eight contiguous registers (registers 45367 through 45374) indicate the presence or absence of configured modules in locations on the island bus. This information is stored in Flash memory. At start up, the actual locations of the modules on the island are validated by comparing them to the configured locations stored in memory. Each bit represents a module: l A value of 1 in a given bit indicates that the configured module is not present.
Data Exchange Emergency Messages The next eight contiguous registers (registers 45375 through 45382) indicate the presence or absence of newly received emergency messages for individual modules on the island. Each bit represents a module: l A value of 1 in a given bit indicates that a new emergency message has been queued for the associated module.
Data Exchange Fault Detection The next eight contiguous registers (registers 45383 through 45390) indicate the presence or absence of operational faults detected on the island bus modules. Each bit represents a module: l A value of 1 in a bit indicates that the associated module is operating and that no faults were detected. l A value of 0 in a bit indicates that the associated module is not operating either because it has a fault or because it has not been configured.
Data Exchange STB NIP 2212 Status Register Register 45391 contains a word of diagnostic data that is allocated to the status of the STB NIP 2212. The bits in the high byte have predefined meanings that are common to all of the NIMs used with the Advantys STB island.
Data Exchange Modbus Commands Supported by the STB NIP 2212 Introduction Modbus is the protocol used by Modicon PLCs. Modbus defines the message structure that the PLCs understand and use, regardless of network type. The Modbus protocol describes the process that a controller uses to access another device, how that device responds, and how errors are detected and reported.

Advanced Configuration Features 8 At a Glance Introduction This chapter describes the advanced and/or optional configuration features that you can add to an Advantys STB island.
Advanced Configuration Features STB NIP 2212 Configurable Parameters Introduction The following information describes how to the configure parameters for the STB NIP 2212 using the Advantys configuration software.
Advanced Configuration Features Selecting the Display Format By default, the values for the configurable NIM parameters use decimal notation. You can change the display format to hexadecimal notation, and vice-versa: Step Action Comment 1 Double-click the NIM in the island editor. The module editor window appears. 2 Select the Parameters tab. 3 Click on the checkbox in front of Hexadecimal at the top right of the module editor window.
Advanced Configuration Features Reserving Data Sizes To transfer data to the PLC from a Modbus HMI panel attached to the CFG port, you must reserve space for that data. To reserve data sizes: Step Action Result 1 In the module editor window, select the Parameters tab. 2 In the Parameter name column, expand the Additional Info Store List by clicking on the plus (+) sign. The configurable NIM parameters are displayed. 3 Double-click in the Value column next to The value is highlighted.
Advanced Configuration Features Assigning the Max. Node ID (CANopen Devices) 890USE17700 September 2003 To assign the highest node ID used by a CANopen device on the island bus: Step Action Comment 1 In the module editor window, select the Parameters tab. Configurable parameters are located under this tab. 2 In the box next to Max. node ID on the CANopen extension, enter a node ID. This node ID represents the last CANopen module on the island bus.
Advanced Configuration Features Configuring Mandatory Modules Summary As part of a custom configuration, you can assign mandatory status to any I/O module or preferred device on an island. The mandatory designation indicates that you consider the module or device critical to your application. If the NIM does not detect a healthy mandatory module at its assigned address during normal operations, the NIM stops the entire island.
Advanced Configuration Features Recovering from a Mandatory Stop Pushing the RST button (See The RST Button, p. 55) while recovering from a mandatory stop will load the island’s default configuration data. WARNING UNINTENDED EQUIPMENT OPERATION/LOSS OF CONFIGURATION—RST BUTTON WHILE RECOVERING FROM MANDATORY STOP Pushing the RST button (See The RST Button, p. 55) causes the island bus to reconfigure itself with factory-default operating parameters, which do not support mandatory I/O status.
Advanced Configuration Features Prioritizing a Module Summary Using the Advantys configuration software, you can assign priority to digital input modules in your island assembly. Prioritization is a method of fine tuning the NIM’s I/O scan of the island bus. The NIM will scan modules with priority more frequently than other island modules. Limitations You can prioritize digital input modules only. You cannot prioritize digital output modules or analog modules of any kind.
Advanced Configuration Features What Is a Reflex Action? Summary Reflex actions are small routines that perform dedicated logical functions directly on the Advantys island bus. They allow output modules on the island to act on data and drive field actuators directly, without requiring the intervention of the fieldbus master.
Advanced Configuration Features Configuring a Reflex Action Each block in a reflex action must be configured using the Advantys configuration software. Each block must be assigned a set of inputs and a result. Some blocks also require that you specify one or more user-preset values—a compare block, for example, requires that you preset threshold values and a delta value for hysteresis. Inputs to a Reflex Action The inputs to a reflex block include an enable input and one or more operational inputs.
Advanced Configuration Features Result of a Reflex Block Depending on the type of reflex block that you use, it will output either a Boolean or a word as its result.
Advanced Configuration Features Nesting The Advantys configuration software allows you to create nested reflex actions. One level of nesting is supported—i.e., two reflex blocks, where the result of the first block is an operational input to the second block. When you nest a pair of blocks, you need to map the results of both to the same action module. Choose the action module type that is appropriate for the result of the second block.
Advanced Configuration Features Number of Reflex Blocks on an Island 890USE17700 September 2003 An island can support up to 10 reflex blocks. A nested reflex action consumes two blocks. An individual output module can support up to two reflex blocks. Supporting more than one block requires that you manage your processing resources efficiently. If you are not careful with your resources, you may be able to support only one block on an action module.
Advanced Configuration Features Island Fallback Scenarios Introduction In the event of a communications failure on the island or between the island and the fieldbus, output data is put into a safe fallback state. In this state, output data is replaced with pre-configured fallback values, ensuring that a module’s output data values are known when the system recovers from a communications failure.
Advanced Configuration Features Fallback States for Reflex Functions Only an output module channel to which the result of a reflex action (See What Is a Reflex Action?, p. 157) has been mapped can operate in the absence of the NIM’s heartbeat message. When modules that provide input for reflex functionality fail or are removed from the island, the channels that hold the result of those reflex actions go into their fallback states.
Advanced Configuration Features Saving Configuration Data Introduction The Advantys configuration software allows you to save configuration data created or modified with this software to the NIM’s Flash memory and/or to the removable memory card (See Physical Description, p. 50). Subsequently, this data can be read from Flash memory and used to configure your physical island. Note: If your configuration data is too large, you will receive a warning message when you attempt to save it.
Advanced Configuration Features Protecting Configuration Data Introduction As part of a custom configuration, you can password-protect an Advantys STB island. This protection restricts write privileges to authorized personnel and prevents unauthorized users from overwriting the configuration data currently stored in Flash memory. You must use the Advantys configuration software to password-protect an island’s configuration.
Advanced Configuration Features A Modbus View of the Island’s Data Image Summary A block of Modbus registers is reserved in the NIM to hold and maintain the island’s data image. Overall, the data image holds 9999 registers. The registers are divided into nine contiguous groups (or blocks), each dedicated to a specific purpose. Modbus Registers and Their Bit Structure Registers are16-bit constructs. The most significant bit (MSB) is bit 15, which is displayed as the leftmost bit in the register.
Advanced Configuration Features The Data Image The 9999 contiguous registers in the Modbus data image start at register 40001.
Advanced Configuration Features Reading Register Data All the registers in the data image can be read by an HMI panel connected to the island at the NIM’s CFG port (See The CFG Interface, p. 33). The Advantys configuration software reads all this data, and displays blocks 1, 2, 8 and 9 in the Modbus Image screen in its I/O Image Overview.
Advanced Configuration Features The Island’s Process Image Blocks Summary 890USE17700 September 2003 Two blocks of registers in the island’s data image (See The Data Image, p. 167) are the focus for this discussion. The first block is the output data process image, which starts at register 40001 and goes to register 44096. The other block is the input data and I/O status process image, which also consumes 4096 registers (45392 through 49487).
Advanced Configuration Features Output Data Process Image The output data block (registers 40001 through 44096) handles the output data process image. This process image is a Modbus representation of the control data that has just been written from the fieldbus master to the NIM. Only data for the island’s output modules is written to this block. Output data is organized in 16-bit register format. One or more registers are dedicated to the data for each output module on the island bus.
Advanced Configuration Features Output Data Read/Write Capabilities The registers in the output data process image are read/write-capable. You can read (i.e., monitor) the process image using an HMI panel or the Advantys configuration software. The data content that you see when you monitor the output data image registers is updated in near-real time. The island’s fieldbus master also writes updated control data to the output data process image.
Advanced Configuration Features The HMI Blocks in the Island Data Image Summary An HMI panel that communicates using the Modbus protocol can be connected to the CFG port (See The CFG Interface, p. 33) on the NIM. Using the Advantys configuration software, you can reserve one or two blocks of registers in the data image (See A Modbus View of the Island’s Data Image, p. 166) to support HMI data exchange.
Advanced Configuration Features HMI Output Data Exchange In turn, output data written by the fieldbus master can be used to update enunciator elements on the HMI panel. Enunciator elements might be: l display indicators l buttons or screen images that change color or shape l data display screens (for example, temperature read-outs) To use the HMI panel as an output device, you need to enable the fieldbus-to-HMI block in the island’s data image (See The Data Image, p.
