Connecting devices with a Modbus-RTU or Modbus TCP interface The Anybus BACnet to Modbus gateway allows Modbus devices to communicate on a BACnet network. The gateway works as a translator between the two networks allowing Modbus RTU, ASCII or TCP-devices to show up as individual BACnet-compliant devices on a BACnet/IP network. This enables central control and supervision of Modbus devices in a building for example.
Where BACnet is used BACnet is a data communication protocol mainly used in the building automation and HVAC industry (Heating Ventilation and Air-Conditioning). The most common serial version is called BACnet MS/TP while the dominant Ethernet version is BACnet/IP. Modbus remains a popular protocol. It is frequently used on mechanical equipment: - Boiler controls - Variable speed drives - Metering applications
Modbus is simple to use but not BACnet compliant. This is where a gateway between Modbus and BACnet is needed!
How it works Modbus RTU and Modbus ASCII networks are connected to the serial port of the gateway, while Modbus TCP and BACnet/IP networks are connected to the Ethernet port. You will need to create a device profile for each Modbus device and upload this to the gateway.
