| Communication
between the Intouch and Ultrasonic Level Meter
|
|
Solution:
|
| With the proposal of "The Industrial
Internet of Things", the industrial field application is to convert different application protocols
into Ethernet, in order to enhance the field communication speed and quality. Modbus TCP is one of
the industrial Ethernet protocol, which is the most commonly used in field applications. This
application case is a specific application of data communication between the Intouch with Modbus TCP
protocol and Ultrasonic level meter with HART protocol.

|
Conclusion: |
| The GT200-3HT-MT implements that
Modbus TCP master can communicate with three meters on the HART loop at the same time, three
independent HART channels, each channel can set up to 100 commands, Modbus TCP can support up to 36
connections, Modbus TCP can support 512 command requests at the same time. Through the specific
configuration software, Ethernet parameters, HART channels and command parameters can be quickly
configured. All devices with a HART slave interface can be connected to the HMI with Modbus TCP.
