Official Full Product Name & Function Description Official Full Order Name: ABB CI522A AF100 Interface Module, Order Code: 3BSE018283R1 Official Long Function Description (ABB datasheet): This is a dedicated backplane plug-in communication coupler designed for ABB Advant OCS / System 800xA DCS platforms. It acts as a bridge between AC800M series process controllers and distributed S800 I/O stations over the AF100 industrial fieldbus. It provides dual redundant AF100 DB9 communication ports to eliminate single-point communication failure for critical process loops. The module transmits real-time analog/digital I/O data, executes controller-to-field station cyclic polling, runs built-in bus diagnostics, and supports hot-swap replacement without system shutdown. It is widely deployed in power
