Modbus remains a popular network interface. It is commonly found on jobs such as boiler control, variable speed drives, and metering applications, but these devices lack BACnet compliance. To make Modbus devices appear as individual BACnet devices a BASgatewayLX is used.
The BASgatewayLX is attractive to systems integrators because it is a proven solution for integrating Modbus devices into a BACnet inter-network.
To make things even easier, our sales manager, Joe Stasiek, has developed a Modbus Device Profile Library for more than 40 popular product models. The system integrator downloads the specific device profile into the BASgatewayLX and checks off only those registers needed to be scanned. Up to 30 Modbus devices - the same type or different - can be scanned by each BASgatewayLX using a technique call virtual routing. Each connected Modbus device appears as a virtual BACnet device. Up to 1000 registers can be marked for scanning. It is simple and effective.
For the systems integrators who want the capability to make their own profiles or modify profiles in the field, we have published an application note that defines the data format we use when developing device profiles.
If our Device Profiles Library doesn't include a product model you are interested in, feel free to contact Joe and he'll do the work to add that profile to our library.
