Chipkin Announces an Update to the CAS BACnet Stack - Enhanced Support for BACnet BIBBs - COV

Chipkin Automation Systems Inc. is proud to announce a much-anticipated update to the CAS BACnet Stack. This update provides added support for these BACnet BIBBs: DS-COVP-B and DS-COVM-A, DS-COVM-B.
VANCOUVER, British Columbia - Aug. 24, 2020 - PRLog -- The newest version of CAS BACnet Stack is now available from Chipkin Automation Systems Inc. with enhanced features. Chipkin has added support for the following BACnet BIBBs:
● DS-COVP-B - Subscribe COVProperty - Adds the SubscribeCOVProperty Service
● DS-COVM-A, DS-COVM-B - Subscribe COV Multiple


COVProperty allows for a BACnet client to subscribe to a specific property of a BACnet object. Unlike the basic COV subscription that only allows for subscriptions of the present_value and status flags. Subscribe COVProperty service also allows for BACnet clients to subscribe to vendor proprietary property. Real-World Example: This can be useful for monitoring a change of value to the units of a sensor. The BACnet client would then be notified when the sensor changes the units and could update a HMI accordingly


COVMultiple allows for a BACnet client to subscribe to multiple BACnet objects in a single message. When any of the subscribed values are updated on the BACnet server, a single message is sent to the BACnet client. This can significantly reduce COV bandwidth consumed. COV Multiple also has a parameter for Max Notification Delay parameter. This parameter tells the server that it must send a COV Notification within the delay time. That means it can compile the changes and send them all out in one message.
