Add or remove tags

When tags are added or removed from the Logix5000 processor, the Communication Driver can detect the change and update its internal tag database. If the newly added tags have already been accessed in your application, the quality of these tags will be changed to GOOD and their values updated. In the case when the tags are removed from the processor, the tags’ quality will be changed to BAD.

Because the detection is done through periodic pollings of your Logix5000’s status, there will be a delay between the time when tags are modified and the time when tags’ information is updated in your application. The delay can be a few seconds to minutes, depending on how busy your Communication Driver is.
