Modbus remains a popular network interface. It is commonly used with boiler control,
variable speed drives, and metering applications but these devices lack BACnet
compliance. To make Modbus devices appear as individual BACnet devices, the
BASgatewayLX is used. This device has one 10/100 Mbps Modbus TCP or BACnet/
IP Ethernet port and an opto-isolated Modbus EIA-485 serial port for Modbus RTU or
Modbus ASCII devices.
Up to 30 Modbus serial devices can share the unit’s Modbus port and up to 1000
Modbus registers can be processed. The virtual routing feature in the BASgatewayLX
allows each connected Modbus device to appear as an individual BACnet-compliant
device. What is needed is a device prole for each Modbus type device. Contemporary
Controls maintains a library of common device proles. If one is not available,
Contemporary Controls will provide it upon request. Custom device proles can be
uploaded to the gateway.
Using web pages and a resident database of common Modbus device proles, Modbus
registers from Modbus Serial devices can be mapped to BACnet objects.
