IEC_BACNET_PROPERTY_REFERENCE

This parameter, of type BACnetPropertyReference, contains the property identifier and optional array index for which a subscription is desired. If COV reporting is supported for a property that has an array datatype, it is a local matter to determine whether to support COV subscriptions for all elements of the array or only for particular elements in the array.

fCovIncrementPresent

IEC_BACNET_BOOLEAN

If set to True the covIncrement parameter is valid.

covIncrement

IEC_BACNET_REAL

This parameter, of type REAL, specifies the minimum change in the monitored property that will cause a COVNotification to be issued to subscriber COV-clients. This parameter is ignored if the datatype of the monitored property is not numeric. If the monitored property is Present_Value, its datatype is numeric, this parameter is not present, and the monitored object has a COV_Increment property, then the COV increment to use is taken from the COV_Increment property of the monitored object. The intent is to allow the subscriber to use a previously established COV increment from another subscription or to allow use of the COV_Increment property in the monitored object.

timestamped

IEC_BACNET_BOOLEAN

This parameter specifies if the COV notifications shall be sent with a time stamp or not.
