Network Interface Module (also part no YINNIS21, PINNIS21).
The Bailey Controls INNIS21 is a Network Interface Slave module manufactured by ABB (formerly Bailey Controls) for the Infi 90 / Harmony distributed control systems (DCS).
Purpose & Function
- Communication: Designed to link computer nodes (like an ICI13 interface) to the Cnet communication network, facilitating data transfer between human-machine interfaces (HMIs) and the control system.
- System Integration: Primarily used in INFI-NET to Computer Transfer Modules to allow PC-based controllers or historian nodes to communicate with the rest of the Bailey control network.
