With the diagnostics error interrupt interrupt OB, you are notified of new devices entering a problem state as well as when they enter a non-problem (everything is back to normal) state. You can also periodically poll the device for data that is always non-zero. You can add a parameter to your telegram for sign-of-life bit that toggles at a set frequency, then monitor it for either on or off longer than the toggle frequency. Lots of solutions available, but the most responsive is to accept the diagnostics error and handle it.

DeviceStates is a nice instruction, to poll devices. |
