6 Working Principle

6.1 Data Exchange

Data exchange between HART and EtherNet/IP via GT200-HT-EI is established based on “mapping”. There are

two data buffer areas in the GT200-HT-EI: One is the EtherNet/IP network input buffer and the other is the

EtherNet/IP network output buffer. The received data from the HART instruments will be mapped to the input

buffer for the EtherNet/IP scanner reading. The output data from EtherNet/IP scanner will be mapped to the output

buffer, then the GT200-HT-EI will write the output data to the HART instruments.

For more details and examples, please refer to chapter

4.3
