Connect BACnet MS/TP Subordinate to DH+ Device

Improve your data integration process. Connect a BACnet MS/TP Devices with as many as 32 DH+ devices. A BACnet system can benefit you by providing savings in resources, installation costs, maintenance costs and energy savings.





Control up to 32 BACnet MS/TP Devices from a Serial PLC5 or SLC PLC

You can now control a network of 32 BACnet MS/TP devices from a legacy Allen-Bradley serial PLC. It’s the perfect tool to save legacy PLCs from the scrap pile and control BACnet MS/TP devices directly from the serial port of PLC5s and SLCs. You can now extend the function of the legacy PLCs your already have.

How Do I Use the 460BMDHM-D2E in My Application?

For most applications, the mapping is very straightforward. PLC data table values like N7:200 and F9:1 are mapped directly to BACnet analog and binary values. No message instructions and no ladder logic changes are required to monitor the PLC data on BACnet MS/TP Subordinate.

What Is A BACnet Protocol and What It Can Do for You?

Discover whether connecting DH+ devices to a BACnet/IP System aligns with your specific needs. Check out our BACnet tech page – BACnet is a communications protocol that defines the services used to communicate between building automation end-devices and building control systems. It has an open architecture with the ability to control and monitor any building automation process. BACnet meets the needs of users, integrators, and equipment vendors.

What our Customers are Saying

“I challenged a customer to get it working by the time I got back from his break room with a Coke and he indeed had it working when I got back. He then said, "It’s worth twice the price!"”

Eric P. / Kendall Electric

“Everything seems to be working as we imagined. Thanks for the great response time. I did not see any way to save the configuration other than screen shots, but the configuration did not get lost in the update. Thanks again, and you were a pleasure to work with.”
