Description

COV Period

C,N,W

Null

Units = seconds

Range = 30–86,400

Broadcasts an Unconfirmed COV on a periodic basis. When set to a value from 30 to 86,400, this object issues an Unconfirmed COV containing the attribute value and status flags at least once every period. This broadcast occurs even when the value remains unchanged. If an actual change of value occurs during the period and a COV is sent, the timer for the periodic COV resets. To disable the periodic broadcast feature, clear the value from the COV Period and save the change. The null entry represents not sending period
