> Thanks for investigating Kevin. As per Matthew’s post, I think that what you have described is only currently possible with the S7-1500 which has more OPC-UA options. Is there a plan for adding the custom address space functionality/new attribute to ignition? I have only tested 2 free OPC-UA clients but they were both able to read the whole structures from the S7-1200. Cheers
