Function and Working Principle
The PM591-ARCNET serves as the central processor of an ABB AC500 automation system. It continuously acquires input signals from field devices, executes the PLC application program, processes control algorithms, and updates outputs with high-speed performance.
Its integrated ARCNET interface provides deterministic communication for distributed automation systems. The dual RS232/RS485 serial ports enable communication with drives, intelligent instruments, HMIs, and other industrial devices. The FieldBusPlug (FBP) interface supports additional communication modules, while the SD card slot provides storage for application programs, firmware updates, and system backups.
Operating Sequence
- Field devices send input signals to the processor.
- The CPU scans and processes incoming data.
- PLC logic is executed according to the application program.
- Output commands are transmitted to connected equipment.
- Data is exchanged through ARCNET and serial communication networks.
