I had a Data Type built for data checking with the PLC, but now that the PLC has changed, it seems that Ignition can’t actually do any redirection. This below used to work:
Now, it doesn’t work, despite the path being correct. Here is what works, which is just overriding the DT indirection:
Used to be, to reference top level tags, you had to add “Global.” in between the source and the tag name. That has changed, but what I need to put in there for indirection to work, I simply don’t know. If I drag the tag from OPC to the Tag folder, it shows nothing in there, but clearly there needs to be something.
