Hi

Not sure if this is possible but it would be useful if a check would be done to see if a tag is used in the project before Deleting or Renaming

Aidan

Alternatively could we generate a list or highlight orphaned tags that aren't being used?

That is another good request. I suppose what I am looking for is similar to what a Control Logix can do. It will not allow a Tag to be deleted that is in use and also it will generate a list of all unused tags

Aidan

I think it would be impossible to make an accurate list of which tags are used or not used since tagnames can be constructed on the fly within scripts and through parameter passing to template windows.

I think you might be confusing the difference between a variable and a tag...

Not necessarily. An example is here where tags are created via scripting. The problem that I see is that a tag can be used anywhere, across projects and even across servers, making it difficult to know exactly where a tag is being used.

I retract my previous statement

Don't sweat it. I'll admit that it was an odd duck of an application. But it does show that if it can be done externally (not necessarily through Ignition) to a database, it can also happen to a tag. Learned that one the hard way, once. I had one script to giveth a tag and one script to taketh away.
