7.6 UP_TIME Object (Analog Value: 0)
The object shows the time of module operation module (expressed in seconds) from the
last power-up or the module reset.
7.7 WATCHDOG Object (Analog Value: 1)
The object specifies the time (expressed in seconds) to watchdog reset. If the module
does not receive any valid BACnet message within that time, all PRIORITY_ARRAYs will be
set to null, and the PRESENT_VALUE for outputs will be set to the RELINQUISH_DEFAULT
value.
This feature is useful in case of an interruption in data transmission, and if, for security
reasons, output states must be set to the appropriate state in order to avoid endangering
the safety of persons or the property.
The default value is 0 seconds, which means the watchdog function is disabled. To
maintain the compatibility, this object is also available as the Device object property 5001.
If the watchdog is triggered, the power LED blinks with the specified sequence (3 blinks
with 20 Hz frequency and 1-second pause).
