A high-capacity AC500 processing platform combining Ethernet networking, dual serial communication, retained data memory and modular expansion support.
ABB PM590-ETH is an AC500 Ethernet PLC CPU designed for coordinated machine and process control within modular automation architectures. The CPU combines 24 V DC operation, large program and data memory, an integrated Ethernet interface, two serial interfaces, battery-backed data retention and a real-time clock. Its communication functions support engineering access, Modbus TCP, OPC, web-server use, Modbus master or slave operation, ASCII communication and CS31 expansion through COM1. It is suitable for new panel projects, controlled system upgrades and replacement procurement where the exact CPU label, project environment, communication settings and installed expansion arrangement are verified before ordering.
