Overview
The Bailey INNIS01 is a network interface slave module (NIS) designed for ABB’s Infi 90 OPEN and Symphony Harmony distributed control platforms. The INNIS01 works in conjunction with the INNIPM01 Network Processing Module to form a process control unit interface that provides control modules access to an INFI-NET® communication system. It serves as a communication gateway that links controller-level modules with plant-wide supervisory networks, enabling coordinated data exchange across large-scale industrial systems.
Key Features
- Enables nodes to communicate with any other node on the INFI-NET loop
- Single-slot installation in the INFI 90 OPEN mounting rack with direct backplane interface
- Power supplied through system backplane, eliminating the need for external wiring
- 16 LEDs on the faceplate for displaying error codes and event/error counts
- Supports up to 62,500 nodes across the system architecture
- Ten-megabaud communication rate for timely information exchange
