How to Select an Interface Relay for PLC Outputs
A step-by-step guide to matching PLC output type, coil voltage and current, contact rating, and socket style when selecting an interface relay.
The ABB 1SAP172900R0011 (CM589-PNIO) is an AC500 communication module that connects the CPU to a PROFINET network as an IO RT device, with 2 switched Ethernet interfaces running at up to 100 Mbit/s. It plugs into the CPU's expansion bus, letting an upstream PROFINET controller exchange process data with the AC500 program.
As a device rather than a controller, this module answers an upstream PROFINET master; pick the PROFINET IO RT controller module instead when the AC500 itself must act as the PROFINET master over the connected devices. The built-in switch on both Ethernet ports supports daisy-chaining to the next PROFINET device without an external switch.
