A European industrial automation customer was maintaining an ABB S800 I/O based control system used in a continuous process automation application. The existing communication interface required replacement, but the customer wanted to keep the existing ABB control architecture and minimize system downtime.
After checking the system requirements and part number, the customer selected the ABB CI801 3BSE022366R1 Communication Interface Module as the replacement component.
The CI801 is an ABB S800 I/O communication interface designed to provide communication between the S800 I/O system and the control system through PROFIBUS DP-V1. It is suitable for industrial process control and automation applications where reliable I/O communication and system diagnostics are required.
