Virtual Input Module digital inputs and analog inputs keep resetting
Problem: The Virtual Input Module’s digital inputs are set through the Operator’s
Workstation and the system reacts to the change in state. After several minutes, all the
digital inputs on the Virtual Input Module are reset.
Diagnosis: Check the BACnet Watchdog configuration settings. The system will reset all
the digital inputs and analog inputs on all Virtual Input Modules if the Intelli-Hood system
receives no BACnet communication for the time specified by the BACnet Watchdog
parameter (default setting of five minutes). Any BACnet communication directed toward
the Intelli-Hood system, including reading data points, will restart the watchdog timeout.
Either extend the BACnet Watchdog timeout or query the Intelli-Hood system often
enough to reset the watchdog timeout.
