DESCRIBE

The ABB MS571 is a loop switch / communication continuity module used in modular switchgear communication networks. It provides multiple network ports (e.g., Ethernet and BUS ports) that allow data communication between control modules in a ring or loop architecture. When a removable controller module is inserted, it connects to the loop through the MS571; if removed, the MS571 automatically bypasses the controller so the communication ring remains intact. This helps maintain system network integrity during maintenance or module replacement.
