• PN: INNIS01
• Brand: ABB (Bailey)
• Series: INFI 90 / Symphony DCS Distributed Control System
• Type: Network Interface Slave Module (NIS)

• Function: Serves as the communication bridge between process control unit (PCU) and INFI-NET plant-wide control loop, works with NPM network processing module to realize high-speed inter-node data transmission, realizes real-time upload of field analog/digital signals, control logic interaction and multi-control cabinet networking communication.

Core Features

1. Support optional communication rate: 2Mbps / 10Mbps, deterministic industrial communication, stable data transmission under complex electromagnetic interference environment
2. Equipped with 208KB RAM + 64KB ROM, powerful data processing capacity, supports up to 250 nodes in single loop and 62500 nodes for the whole system
3. Single-slot hot-swappable design, no system shutdown required for online replacement and maintenance
4. DIP switch for flexible configuration of node address, loop address and communication mode, convenient on-site parameter setting
5. Dual-channel redundant loop communication design, effectively avoids single-line communication failure and improves system operation reliability

6. Built-in hardware self-diagnosis function, real-time monitoring module running status, network communication fault and abnormal address configuration
