hello,
is there a way to read the LinkOK (link state) for the ETH port in X20,X90 PLC , like the LinkOK IO MAP for the PLK port?
thank you.
Hi Ron,
I don’t think there are any diagnostics available for Ethernet in general, but different communication protocols have diagnostics available. You can also use the IcmpPing function block to test that your PLC is able to connect to a certain device/server.
