thanks for Network Programming Overview
This functionality was added as of Aug 2019 so you may need to update your firmware and T3000 front end.

If the T3 is running a program please send that on and we’ll see if we can duplicate the problem. You can also disable the programs one by one and see if there’s any correlation there.
