INNIS01 Network Interface Slave Module BAILEY

Description

Overview

Essential details：INNIS01 Network Interface Slave Module BAILEY

The INNIS01 Network Interface Slave Module (NIS) and the INNPM11 Network Processing Module (NPM) make up a process control unit interface. This process control unit interface provides control modules in a process control unit with access to an INFI-NET® communication system.
This instruction explains process control unit interface features, specifications and operation. It also includes installation and troubleshooting procedures for each module.
The system engineer or technician using this interface should read and understand this instruction before installing any modules. In addition, a complete understanding of the INFI 90® OPEN system is beneficial.

INNIS01 

OVERVIEW
INFI-NET is a unidirectional, high-speed serial data highway shared by all INFI 90 OPEN nodes. INFI-NET provides sophisticated interfaces for data exchange. This process control unit interface is made up of state-of-the-art INFI 90 OPEN modules.
INTENDED USER
Personnel installing, operating or maintaining the process control unit interface should read this instruction before performing any installation, operation or maintenance procedures. Installation requires an engineer or technician with experience handling electronic circuitry and who is familiar with communication networks.
PROCESS CONTROL UNIT INTERFACE DESCRIPTION
The process control unit interface is made up of the INNIS01 Network Interface Slave Module (NIS) and INNPM11 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 (refer to 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.
