ABB CI867 3BSE043660R1 AC 800M Modbus TCP Communication Module

Description

The CI867 3BSE043660R1 facilitates the exchange of process data and diagnostic information over copper Ethernet media. It mounts directly onto the CEX-Bus of the AC 800M CPU, ensuring low-latency communication and high reliability. The module supports both Master (Client) and Slave (Server) roles simultaneously, providing maximum flexibility for complex network topologies. In critical applications, the CI867 can be deployed in redundant pairs to ensure continuous data flow and system availability in the event of a hardware or cable failure.
