CI854BK01
Product Overview
CI854BK01 (Order Code: 3BSE069449R1) is the PROFIBUS DP-V1 Master Communication Interface Module (CI854B) manufactured by ABB for AC 800M / System 800xA DCS platform.
This assembly includes CI854B communication unit + TP854 baseplate. It acts as PROFIBUS-DP master gateway, connecting AC800M controller to PROFIBUS field network, realizing cyclic I/O data exchange and acyclic DP-V1 service communication. It supports line redundancy via dual DB9 PROFIBUS ports, and can configure master redundancy for high-reliability control loops.
Commonly connected to S800 remote I/O, variable frequency drives, flow meters and other PROFIBUS slave devices in power and process industries. It is the upgraded successor of CI854AK01.
