The read of the state works well. Thank you!
I am still having a problem with the Write of the Connect or Disconnect. It seems from your example that there is no value needed for the "Value" input, that simply writing to 'opcuaclient/xxxx/connect' is enough. But when this did not work, I tried a boolean value. This resulted in the same errors displayed below. The error codes, 0D0A0201 with 80E50000, are not documented that I can find. This is the same problem I had in my previous attempt though the error codes are now different.
Can you suggest what is wrong here? I attached an XML export of my POU.
