The VLT® BACnet/IP MCA 125 option from Danfoss is a plug-and-play solution that allows connection of the VLT® HVAC Drive to building management systems using the BACnet/IP protocol.

With the VLT®BACnet/ IP MCA 125 option, the company says the Danfoss Drives elevate the performance of a BACnet-enabled AC drive by complying with the B-AAC (BACnet Advanced Application Controller) profile. Some of the features of the VLT® BACnet/IP MCA 125 include subscribe COV which reduces polling for data from the BMS , alarm and event management that can automatically send alarms without polling, and trend object which allows the user to trend inside the drive and not tie up the BMS. Officials said all of these features increase the network bandwidth through reduced polling and data transfer, allowing for higher numbers of network devices and reducing irrelevant data communication on the network.

The module also incorporates battery-free clock synchronization with the BMS eliminating periodic battery maintenance and disposal. The VLT® BACnet/IP MCA 125 can also send alarms or detailed reports of triggered conditions.
