I don't know anything about TIA Portal, but the first question that anyone is going to ask you is to provide a screenshot of your driver configuration. How do you have it connected. The screenshot you provided doesn't provide much information. ---

Hi, The error message is just a consequence, it tells you that Ignition tried to write a tag (maybe OPC) and this one is bad. I think your connection is faulted, or your tagpath is wrong. What is your configuration inside your gateway ? Have you check the address IP in your connection ?
