ABB CI856K01 3BSE026055R1 Communication Interface

III. Functional Features
Hot - swap function: It supports the hot - swap feature, which means that during the operation of the system, maintenance personnel can directly replace the faulty module without stopping the machine. This function greatly improves the convenience and efficiency of system maintenance, avoids production stagnation caused by module failure shutdown, effectively reduces maintenance costs and time costs, and ensures the continuity and stability of the production system.
Code locking device: It is equipped with a code locking device, which can prevent the wrong installation of incompatible components and ensure the stability and reliability of the system from the hardware level. During the equipment installation and maintenance process, it effectively avoids system faults caused by the wrong installation of components due to misoperation and improves the overall safety of the system.
I/O system compatibility: It can seamlessly connect the AC 800M system and the S100 I/O system to realize efficient communication between devices of different architectures. This compatibility advantage enables enterprises to make full use of the existing S100 I/O equipment resources when upgrading or transforming the automation system, protect past investments, and at the same time integrate them into the advanced AC 800M control system to optimize equipment performance and improve system functions.
Strong expansion capability: It can connect up to 5 S100 I/O racks, and each rack can accommodate 20 I/O boards, providing a broad space for the expansion of the system's I/O points. Enterprises can flexibly add I/O equipment according to the expansion of production scale or changes in process requirements to meet the needs of monitoring and controlling more on - site equipment and improve the adaptability and flexibility of the system.
