Function and Working Principle
The PM590-ETH serves as the central controller of an ABB AC500 automation system. It continuously acquires signals from field devices, executes the user-defined PLC program, processes control algorithms, and updates output signals in real time.
Its integrated Industrial Ethernet interface enables communication with HMIs, SCADA systems, engineering workstations, and remote controllers. The dual RS232/RS485 serial interfaces support communication with drives, sensors, meters, and other serial devices. The FieldBusPlug (FBP) interface allows additional communication modules to be installed, while the SD card slot provides storage for applications, firmware updates, and backup files.
Operating Sequence
- Field devices transmit input signals to the controller.
- The CPU scans and processes the received data.
- Control logic is executed according to the application program.
- Output commands are transmitted to connected equipment.
- System data is exchanged through Ethernet and serial communication networks.
