The 460MMBMS moves data between up to 32 Modbus RTU slaves and a BACnet MS/TP BAS. It’s a perfect tool to tie Modbus power meters, boilers, chillers and other devices into your BACnet MS/TP Building Automation System.
Best of all the product is made in the USA, is always in stock and comes with a five-year warranty.
For most applications the mapping is very straight forward. Modbus register data is mapped to BACnet analog objects and Modbus coil data is mapped to binary objects on BACnet. The only additional piece required for BACnet is adding meta data which is nothing more than an ASCII description of each object. No other deep understanding of either protocol is required to configure the gateway.
It really is that simple. Need to modify your data as it passes from one protocol to the other? No problem. Each data mapping you apply can be modified with up to three mathematical functions. Add four to a value, multiply by four and divide by 10 with ease.
You can both send and receive data to and from your Modbus RTU slave devices. Registers and coils in the Modbus RTU slaves are mapped directly to BACnet MS/TP properties of Analog Input, Analog Output, Binary Input, and Binary Output. Up to 150 Analog Inputs, 150 Analog Outputs, 1600 Binary Inputs, and 1600 Binary Outputs can be mapped to registers and coils in up to 31 Modbus RTU slave devices.
The 460MMBMS provides an option to access Modbus RTU slave devices on your BACnet MS/TP master. While there are certainly a number of other companies offering stand alone gateways, there is no one who provides the level of support and service that you receive from RTA.
When you call, a live person answers the phone. When you talk with sales, you will get honest answers and recommendations even if that means recommending someone else’s solution. When you get support, it is from an engineer who had a hand in the product’s development, and support doesn’t require a ticket or 24 hour wait.We are unashamed of the fact that we are a smaller company because that means you mean a lot more to us.
“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!"”

“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.”
