BACnet COV Throttling
Enable COV Throttling
Under normal circumstances, COV Throttling should be enabled to prevent
excessive network traffic if an object's COV Increment is set too low. See
EXCEPTION below.
When enabled, if an object generates excessive COV broadcasts (5 updates in 3
seconds), the driver automatically throttles the broadcasts to 1 per second. Also,
if the object's value updates excessively for 30 seconds, an alarm is sent to the i-
Vu® application listing all objects that are updating excessively. A Return-to-
normal alarm is sent only after all objects have stopped updating excessively.
EXCEPTION: In rare circumstances, such as process control, a subscribing object
may require COV updates more frequently than once per second. For these
situations, clear this checkbox, but make sure that your network can support the
increased traffic. You will also need to disable the
Excessive COV
alarms under
the driver's
Common Alarms
.
