Hi everyone.

I have a PLC S7-mEC 31, and I need to communicate with ABB´s relay REF630, with IEC61850 protocol.

How can I do this communication with the step7? Did I need a especific library of the IEC61850, or some device that convert the protocol IEC61850 to my PLC protocol?

thank you everybody

Guilherme

Hello,
There are libraries available here in the link below.
If the PLC takes initiative, it is a client.

EC 61850 meets SIMATIC
