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](https://help.br-automation.com/#/en/4/libraries%2Fasicmp%2Ffbks%2Ficmpping.html) function block to test that your PLC is able to connect to a certain device/server.
