Introduction 1 At a Glance Summary This chapter describes the Advantys STB NIB 1010 basic INTERBUS network interface module and its role in making the island a node on an INTERBUS open fieldbus network.
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. Island Bus I/O A basic Advantys STB island can support up to 12 Advantys STB I/O modules.
Introduction What Is a Network Interface Module? Purpose An island of STB I/O modules requires a network interface module (NIM) in the leftmost location of the basic island. 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 Structural Overview 12 The following figure illustrates the multiple roles of the NIM.
Introduction About INTERBUS Introduction INTERBUS implements a master/slave network model. It can communicate with up to 512 nodes over a distance of 12.8 km, and can read 1024 inputs and write 1024 outputs in 4 ms. Each network slave has an in connector for receiving data and an out connector for transmitting data on the ring. The last device automatically closes and terminates the network ring; sometimes this last device has no out connector.
Introduction Physical Layer The physical layer contains a single twisted pair of shielded wires. The STB NIB 1010 INTERBUS implements the SUPI 3 (serial universal peripheral interface) ASIC from Phoenix Contact. Network Topology The INTERBUS network observes a master/slave model with active ring topology, having all devices integrated in a closed transmission path.
Introduction Node Addressing The INTERBUS master device is self-configuring because INTERBUS slave devices are auto-addressed according to their sequence in a serial ring structure. The master identifies read/write data in terms of a node’s relative position in the ring, not by a fixed address. The sequential location of slaves corresponds to the order of input and output data in the master's buffer. The ring structure uses a distributed shift register.

The STB NIB 1010 Basic NIM Module STB NIB 1010 Fieldbus Interface Summary The fieldbus interface on the STB NIB 1010 is the point of connection between an Advantys STB island bus and the INTERBUS network. Like every INTERBUS node, the NIM has two nine-pin SUB-D connectors for data reception (in) and transmission (out). The connectors are located on the face of the NIM.
The STB NIB 1010 Basic NIM Module The pin-out for both the in (upper) and out (lower) connectors should be according to the table below (pin numbers correspond to callouts in the figure above): Pin Signal (in) Signal (out) 1 DO1 DO2 2 DI1 DI2 3 GND1 GND 4 unused unused 5 unused +5 V 6 /DO1 /DO2 7 /DI1 /DI2 8 unused unused 9 unused RBST (see note below) Note: The RBST pin detects the presence of a subsequent node on the ring.

Label Pattern Meaning BA (green) on The module is transmitting data messages on the network. off The module is not transmitting data messages on the network.
The STB NIB 1010 Basic NIM Module 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 Advantys STB island is the two-receptacle connector illustrated below.
The STB NIB 1010 Basic NIM Module 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 NIB 1010 Basic NIM Module 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 basic segment. External Source Power Input from an external 24 VDC power supply is needed as the source power for the NIM’s built-in power supply.
The STB NIB 1010 Basic NIM Module 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. Characteristics of the External Power Supply The external power supply needs to deliver 24 VDC source power to the island.

Configuring the Island Bus 3 At a Glance Introduction The information in this chapter describes the auto-addressing and autoconfiguration processes. This data is saved to Flash memory automatically.
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 engage in data exchange. About the Island Bus Address An island bus address is a unique integer value in the range 0 through 127 that identifies the physical location of each addressable module on the island. Address 127 is always the NIM’s address.
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 3425 24 VDC four-channel digital input module 6 STB DDO 3415 24 VDC four-channel digital output module 7 STB DDI 3615 24 VDC six-channel digital input module 8 STB DDO 3605 24 VDC six-channel digital output module 9
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, you can begin using it as a node on that network. About AutoConfiguration Auto-configuration occurs when: l You power up an island for the first time.
Configuring the Island Bus The RST Button Summary Use the RST function to reconfigure your island after you have added a new I/O module to a previously auto-configured island. If a new I/O module is added to the island, pressing the RST button forces the auto-configuration process. The updated island configuration data is automatically saved. RST works only after the island has been successfully configured at least once.
Configuring the Island Bus 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 predefined fallback state so that the module’s values are known when the system recovers from the failure. When you use a basic NIM, you cannot change the fallback parameters of any modules in the segment. All output channels on the modules go to a predefined fallback value of 0.
Fieldbus Communications Support 4 At a Glance Introduction This chapter describes how the INTERBUS master sets up communications with an Advantys STB island and the network parameterization, configuration and diagnostics services performed to configure the island as an INTERBUS node. To communicate with an Advantys STB island, the INTERBUS master sends output data across its network to the STB NIB 1010 basic NIM. The NIM transfers this output data across the island bus to the destination output modules.
Fieldbus Communications Support The INTERBUS ID Code Introduction The ID cycle is part of the INTERBUS network’s initialization process. After determining the length of its own data during network initialization, every network device reports its functionality and byte length in the two-byte ID code. The INTERBUS ID code is a 16-bit word that describes the data type, data length and module type (digital/analog, input/output/mixed) of network devices.
Fieldbus Communications Support Data Length The following table shows the relationship between the actual data length of the island and the length of the code on INTERBUS. The actual data length (anywhere from 0 to 16 words) represents the greater of the input or output data length.
Fieldbus Communications Support Data Exchange Introduction Process image data is exchanged between the STB NIB 1010 NIM and an INTERBUS fieldbus master in a bit-packed format. Note: In this discussion, data and words described as input and output are defined relative to the master. For example, the master receives input data and transmits output data.
Fieldbus Communications Support The Internal Process Image The STB NIB 1010’s process image contains memory areas (buffers) for the temporary storage of input and output data. The internal process image is part of the NIM’s island bus scanner area. The island bus manages data exchange in both directions: l input data from the island bus—The island bus scanner operates continuously, gathering data as well as status and confirmation bits and putting them into the process image’s input buffer.
Fieldbus Communications Support Input and Output Data Exchange The application of the INTERBUS bit packing rules to the sample island assembly results in four words of output data and five words of input data. The tables that follow show how digital data is bit packed for optimization, and how data, status, and echo output data (from outputs) appear in the PLC as the same data type (digital input data). In these tables, N refers to the island node number.
