Danfoss Introduces a New Option Card for Cost-Effective Networking

August 2, 2016   CCE




The VLT® BACnet/IP MCA 125 is an interface connecting the VLT® HVAC Drive FC 102 to building management systems using the BACnet/IP protocol. This option helps to reduce the number of network components and effectively increases network bandwidth to the BMS controller.

The VLT® BACnet/IP MCA 125 option 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, Danfoss Drives elevates the performance of a BACnet-enabled AC drive to unseen heights, 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.  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.

Ethernet ports

The embedded two port managed switch of the VLT® BACnet/IP MCA 125 allows the use of line, star, or ring topology and often eliminates the need for an external switch.  This approach is becoming more attractive because it reduces the number of network components, hardware and installation costs, and reduces points of communication failure.
