PM583-ETH, article 1SAP140300R0271, is an ABB AC500 standard processor module with 1024 kB memory. It operates from 24 V DC and combines onboard Ethernet with two configurable RS-232/485 interfaces, one FieldBusPlug interface, an integrated display and a memory-card slot.

The Ethernet interface supports 10/100 Base-TX communication through the matching Ethernet terminal base. Controller services include the integrated web server, SNTP time synchronization and IEC 60870-5-104 within a configured AC500 system.
