ABB MSR04XI serial communication module

ABB's MSR04XI is a serial communication module specifically designed to provide a serial interface between SC300Es and at least RS232-C compliant environments and a variety of remote devices. This module plays a critical role in the system and must be installed in slot 10 to support communication between the system processor and other host workstations.

The workstation link is mainly used to load application software and monitor ladder and diagnostic functions. This link mainly uses port 0 of the module. In addition, the add-on module can be adapted to any other I/O slot, which prevents "misslotting" by mechanically coding the block. The system software identifies modules by built-in hardware identifiers, ensuring that they operate correctly.

Communication connections are made primarily through four identical ports (ports 0 to 3) on the front panel, which are also replicated on the field connector (J2) on the rear. The fifth port is used only for diagnostic purposes. In addition, the module is compatible with "single slot hot repair" and the front end, and there is a switch on the panel that can request to take the module offline.

In terms of electrical performance, the module has circuit tripling and voting procedures, making it single fault tolerant. Indicators on the front panel show Tx/Rx activity, circuit online status, and module health to help users quickly identify and resolve potential issues. In addition, the module has a power consumption of 3.5W, a total size of 400(9U) H x 397L long x 28W wide (or 15.75h x 15.63L hours x 1.1W hours), and a weight of 1.3k.

Overall, ABB's MSR04XI serial communication module is a fully functional and stable device for industrial automation systems that require efficient and reliable serial communication.
