The ABB INNIS11 serves as a slave communication interface module within the Bailey Infi 90 system. It enables data exchange between system processors (such as the INFI 90 Processors) and intelligent field devices or subsystem components. Functioning as a key link in the communication chain, the INNIS11 ensures consistent and accurate data flow within distributed control architectures.
Housed in a standard module chassis, the INNIS11 plugs into the module mounting unit and operates with minimal configuration. It provides critical network routing and management features for slave devices, effectively bridging them with control units and operator stations.

Functional Characteristics
- Slave Interface Role: Acts strictly as a communication slave; it does not initiate communication but responds to master module requests.
- Data Consistency: Ensures integrity and synchronization of process data by buffering and validating transmissions.
- Multi-Drop Support: Can be used in systems where multiple INNIS11 modules communicate with a single master over a shared bus.
- Auto Reconfiguration: In the event of a communication fault, the module can reset and attempt to reestablish connectivity automatically.
- Fault Isolation: Diagnostic LEDs and self-checks help quickly identify and isolate communication or hardware issues.
- Seamless Redundancy: Supports redundant network configurations, improving system uptime and fault tolerance.
