Connect BACnet/IP Servers to a Modbus RTU Master

Easily connect up to 32 BACnet/IP Servers to a Modbus RTU Master





Connect BACnet/IP Servers to a Modbus RTU Master
The 460MRSBC moves data between a Modbus RTU Master device and up to 32 BACnet/IP Server devices. The 460MRSBC module bundles your BACnet/IP data and makes it available as Modbus RTU data. The module provides complete Modbus RTU Slave and BACnet/IP Client capability.

How Do I Use the 460MRSBC in My Application?
To your Modbus RTU Master device the gateway acts as a Modbus RTU Slave. To your BACnet/IP Server devices the gateway acts as a BACnet/IP Client.

You can both send data to your BACnet/IP Server devices and read current status data. Data is mapped between a BACnet/IP device and Modbus RTU using BACnet/IP properties. Up to 1200 analog and 1600 binary objects can be mapped into or out of up to 512 contiguous registers and coils in the Modbus RTU Master.

It’s really that simple.

Why Use Real Time Automation as a Gateway Supplier?
The 460MRSBC provides an option to access BACnet/IP data on a Modbus RTU network.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. Try the RTA difference today!

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.”
