I’m developing a project where I need to communicate with a AB Compactlogix L33ERM firmware version 28. I imported all PLC tags directly from the OPC Browser window. After doing that, all tags show the correct value and may be written by the Tag Browser, but their quality is Quality Unknown
My Ignition version is 7.9.3 (b2017060210) and I used the Allen Bradley Logix Driver (for firmware v21+) v. 3.9.3 for the device.
Thanks in advance
