ation
The MICRO/I implements the COV function by sending the Confirmed COV Notification service/Unconfirmed COV
Notification service to the report requesting BACnet device according to the parameters contained in the report
request when that report request (Subscribe COV service) was transmitted from the BACnet device.
The key parameters contained in the report request are as follows.
The following diagram shows when the MICRO/I has received a report request transmitted from a BACnet device like
that in the following table.
