I am currently working on a project where IO is not being used but previously was used in the field. In logix for example I have a tag where we have no wires landed it does still reference the slot and channel. This particular tag was only used in a function block routine for alarming. I deleted this routine from the main and the FBD routine because the tag would not delete due to actively being used in a program. When I try to delete this specific tag in "Edit" mode it gives me the following error: Failed to delete object. Can't delete in its current mode/state. But it no longer exist? I have quite a bit of tags not being used but assigned in the particular IO rack and would like to clean it up. Any ideas?
I have had success in some instances where if the tag was actively used somewhere I would cross reference and if Its not used I would delete and this would allow me to delete the tag in the tag list.
