Serial Communication & Automation
The ABB CM574-RCOM provides dedicated serial communication capability for AC500 PLC installations requiring RCOM connectivity. The module uses two RS-232/RS-485 serial interfaces, with one assigned to the RCOM protocol and the other available for console communication.
Communication between the CM574-RCOM and the AC500 CPU is handled through the Dual Port Memory coupler bus, allowing the communication module to operate as an integrated part of the controller architecture. This arrangement provides a modular method of adding serial communication without changing the core CPU.
The module is installed in a compatible AC500 terminal base. Multiple communication modules can be combined on an AC500 CPU, with up to four communication modules supported, allowing communication architecture to be adapted to the requirements of the automation system.
