I am having issues reading program scoped tags on a CompactLogix L35E V17.2. I am using Ignition 7.0.6 on a Windows 7 64-bit PC. There is no problem reading controller scoped tags, but program scoped tags seem to have almost random values in them. For example, I have one program scope tag called “Julian_Day” of type DINT that when I added it into my transaction group it briefly had the value 2147483647 but then changed to 0 (the actual value is 90).
I am using the OPC-UA 1.0.6 server.
I previously tested my application on a ControlLogix L55 V16.21 firmware and did not experience these issues.
