Beaconing Device Status in Gateway

When using the “Is Connected” tag for showing device up/down status in gateway util in 7.7…

If the IP of the connection to the PLC is not valid I get a broken link overlay showing a tag and information symbol and the status in the gateway shows a cycling “Connecting…Connecting: Determining Protocol” then “Disconnected:Defining Protocol” message. I do not see the “0” state which should show a red transparent overlay and conversely a state of “1” which would showing the green transparent overlay if the connection was complete.

Question 1:
Is it possible to get or reference a tag which will show all Six states possible for the connection
(i.e. Connecting: Determining Protocol, Disconnected: Determining Protocol, Connected, Disconnected, Unknown) as shown in the Gateway->Configure->Devices table?

Question 2:
If the connecting process cannot complete due to an invalidor incomplete IP address say and the cycling of “Connecting: Determining Protocol” and “Disconnected: Determining Protocol” does not have a “state” assigned to it, is this what triggers the Broken Tag overlay with the information symbol?

The quality of the “Is Connected” tag shouldn’t be going bad when the connection drops, that’s likely a bug. That being said, the tag having bad quality is probably just as good an indicator that it’s not connected as value=False and good quality. So you could watch for (value=False || Bad Quality) wherever you need the status right now.

There’s no enumeration of states because it’s just a free-form String that each driver implementation is free to use however it wants.
