The Watchdog Timer resets Present_Value of all output objects to Relinquish_Default, if BACnet communication fails permanently. The timer is re-
started, when a BACnet message with an APDU is received.
When the timer times out, the priority arrays of all output objects are completely cleared to NULL.
