PM582-ETH is an ABB AC500 PLC CPU for machine and process-control applications. It provides 512 kB program memory, 288 kB data memory, an RJ45 Ethernet interface and two configurable serial interfaces.
PM582-ETH provides 512 kB program memory and 288 kB data memory. Before migration, compare the compiled program size, retained-data use and CPU firmware requirements; sufficient raw memory does not by itself guarantee project compatibility.
Yes. COM1 and COM2 on PM582-ETH can be configured for RS232 or RS485. The selected physical layer does not automatically define the protocol, so verify the Control Builder configuration, baud rate, framing and connected-device requirements.
Before replacing PM582-ETH, verify CPU firmware, terminal base, memory requirements, Ethernet settings, COM1 and COM2 configuration, wiring and the Control Builder project. Similar AC500 CPU models are not automatically interchangeable.
