Network Interface Slave Module (NIS) INNISO1

The process control unit interface is made up of the INNIS01 Network Interface Slave Module (NIS) and INNPM01 Network Processing Module (NPM). Through this interface the process control unit has access to INFI-NET. At the same time the NPM module communicates with the control modules via the Controlway.

The process control unit interface can support hardware redundancy (see Figure 1-1). In a redundant configuration, there are two NIS modules and two NPM modules. One pair of modules is the primary. If the primary modules fail, the backup modules come on-line. Redundant data highway communication capability is a standard feature.

The NIS module is an I/O module that works in conjunction with the NPM module. This allows a node to communicate with any other node on the INFI-NET loop.

The NIS module is a single printed circuit board that occupies one slot in the module mounting unit. The circuit board contains microprocessor based communication circuitry that enables it to interface with the NPM module.

Two latching screws on the faceplate secure the NIS module to the module mounting unit. There are 16 LEDs on the faceplate that display error codes and event/error counts.
