Change of Value Increment
The change of value increment (COV increment) specifies the minimum change in
present value that causes the controller sending the present value to recipients on
the BACnet bus (e.g. Excel Web HTML Interface, EBI).
The COV increment is also used as the minimum change in the present value for
value-based trending.
NOTE: For the pulse convertor point type, a time-based COV increment is
possible.
Usage with Reference Inputs When using reference input points which read input values, the inputs can be reside
either in different plants of the same controller (internal referencing) or in plants of
different controllers (external referencing).
If the reference input point reads values from an internal referencing plant, the
original datapoint value of the input will be taken.
If the reference input point reads values from an external referencing plant, a copy
of the original datapoint value of the input will be taken. Please note, that in this
case, the COV value must be set to appropriate (low) values in order to minimize
falsification of the transmitted value.

Equivalent
For reference input points, an initial value can be entered, which will be utilized at
system startup if the reference input has not yet received a value from the
connected point.
