I suggest that everybody from time to time are faced to such problem: how detect if one interface stop collect data. I have created a notification based on IORate tag, but I can't detect the case when interface simply stops or hangs -- in this case all tags aren't updated, and IORate tag too. I haven't found proper condition to detect this case -- something like this:


(current_time - time_of_last_value) > deadband


Maybe I can create something custom to implement such condition? Or it can be done with standard tools? Please help me with this problem.
