The following causes a problem.
Add a tag to Ignition V. 7.6.3 where the tag does not exist in a Contrologix plc.
Upon adding the tag to the plc, Ignition will still not find it.
If you browse for the tag in Ignition, it will be listed as a directory with nothing in it rather than a tag.
I’ve only noticed this on DINT data types, but it may be others as well.
Upon shutting down the server and restarting, the tags will appear and upon browsing the tags in the plc, the tag will have moved from the directories to the tags and can be selected. This has been a problem in previous versions of Ignition as well.
