4 Typical Application
GT200-BM-2RS can connect Modbus slave devices to Ethernet bus. GT200-BM-2RS is a bridge in the
communication, and completes the conversation between BACnet and Modbus RTU.
The following is the typical application of GT200-BM-2RS.
For example: The above chart multifunction energy monitoring instrument is a current measuring meter with
Modbus slave station interface, the measurement of the current value is stored in the address 40001. In the
SST-BM-CFG, configure the No.03 function code, start address is 0 (corresponds to the Modbus register 40001
address), and then the SST-BM-CFG will be automatically mapped to the BACnet object AnalogInput (analog
input). On the BACnet master PC, the current value can be observed through corresponding AnalogInput.
