Key System Functions

DriveBus Connectivity: Serves as the interface base for CI858 to establish fast, deterministic DriveBus fiber optic or electrical links to ABB drive lineups.

CEX-Bus Routing: Snaps onto adjacent CEX-bus baseplates or connects via TK850 extension cables to maintain control communication across the controller backplane.

Hot-Swappable Module Design: Allows inserting or replacing the hosted CI858 communication card on-line without interrupting CEX-bus traffic or altering drive wiring infrastructure.
