FAQ

Questions Buyers Ask Most

What is PM571-ETH used for?＋

PM571-ETH is an ABB AC500 PLC CPU for compact automation applications. It provides 64 kB program memory, 24 kB data memory and an RJ45 Ethernet interface, with COM1 and COM2 available for configured serial communication.

What memory is available in PM571-ETH?＋

PM571-ETH provides 64 kB program memory and 24 kB data memory, including retained-data capacity defined by ABB. Confirm the existing application size and retained-data use before migrating a project from another AC500 CPU.

Do the RS485 interfaces on PM571-ETH automatically support Modbus RTU?＋

No. PM571-ETH allows COM1 and COM2 to be configured for RS232 or RS485, but the physical interface does not by itself confirm an application protocol. Verify the Control Builder project, protocol configuration and connected-device requirements.

What must be checked before replacing PM571-ETH?＋

Before replacing PM571-ETH, confirm CPU firmware, terminal base, Ethernet settings, COM1 and COM2 configuration, memory requirements, wiring and the Control Builder project. A similar AC500 CPU should not be assumed to be a direct replacement.
