computer, and then click Download:

2.2 Function Demo

HART interface of the gateway GT200-3HT-MT connects with a 2-wire pressure transmitter with slave

address 0. The Ethernet port is connected to the PC through network cable. The configured Modbus POLL

software in PC can simulate to work as a Modbus TCP master, and then you can see the main variable value of the

pressure transmitter in data exchange window:
