Whenever I try to add any variables to my S7 node, I get this error:
My PLC is an S7-1200 1214C DC/DC/RLY
The node will read "Online" without any variables and no errors are posted in the debug.
As soon as I add any variables to the PLC, I starts spamming the error in the picture in the debug,
and I'm not able to read or write to the variable.
