Function and Working Principle
The PM590-ARCNET serves as the central processing unit of an ABB AC500 control system. It continuously collects input data from field devices, executes PLC programs, processes control logic, and transmits output commands in real time.
The integrated ARCNET interface provides deterministic communication for distributed automation systems, while the dual RS232/RS485 ports enable communication with serial devices such as HMIs, drives, barcode readers, and instrumentation. The FBP interface allows expansion with additional industrial communication modules.
