How to monitor the State of a BACnet object to trigger an alarm when the object is manually disabled.

Issue

How to monitor the State of a BACnet object to trigger an alarm when the object is manually disabled.

Product Line

Andover Continuum

Environment

Continuum BACnet Controllers

Cause

User wants to have an alarm annunciated when someone disables a BACnet object such as an Input or Output. This is fairly simple to configure in the Infinity controllers but there does not seem to be the same functionality in the BACnet EventEnrollment configuration.

Resolution

The State attribute cannot be monitored directly from the EventEnrollment. You will need to create; (1) a Numeric and (2) a Plain English program that monitors the original object and sets the Numeric to the value of it's State attribute.

numIn1State =  In1 state

Then setup an EventEnrollment that monitors the Value of the numIn1State numeric and goes into alarm when it is off.
