ABB MSR04XI serial communication module

ABB's MSR04XI is a serial communication module that provides a serial interface between SC300Es, at least for standard RS232-C environments and a variety of remote devices. In the system, a serial communication module must be used and installed in slot 10 to support communication between the system processors as well as communication between the host and workstation.

The main functions of this module include loading application software, monitoring ladder diagram and diagnosis. These functions are mainly implemented through port 0 of the module. In addition, the module has additional modules that can be adapted to any other I/O slot and prevents "misslotting" through mechanical coding blocks. The system software identifies modules by built-in hardware identifiers.

In terms of communication, the MSR04XI module communicates via four identical ports (ports 0 to 3) on the front panel, and these connections are also replicated on the field connector (J2) at the rear. In addition, there is a fifth port dedicated to diagnostic purposes. 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 power monitoring, each output circuit of the MSR04XI consists of two switches in series, controlled by two processors separately. During each cycle, the midpoint voltage of the two microprocessor systems is compared to a threshold, and their results are then exchanged to evaluate the state of the midpoint and diagnose the state of the switch. If an error behavior is detected in a channel, the system stops immediately, and the diagnostic bit is set to notify the CPU, and the fault message is displayed in the CPU.

Overall, ABB's MSR04XI Serial communication module is a powerful and well-designed device that is widely used in industrial automation systems to enable serial communication and data processing between devices. When selecting and using MSR04XI, factors such as product life, continuity and renewal cycle need to be considered to ensure the stability and reliability of the system.
