1 Product Overview
1.1 Product Function
The GT200-HT-MT achieves seamless communication between HART instruments and a Modbus TCP network.
The HART interface can be configured as a primary master or a secondary master. It acts as a server at Modbus
TCP side.
1.2 Product Features
Easy to use: The GT200-HT-MT can achieve seamless data communication with some simple steps;
Ethernet 10/100M adaptive;
Easy-to-use configuration software: The GT200-HT-MT can be configured by SST-HE-CFG software easily;
Debug function: The HART commands can be diagnosed in SST-HE-CFG, which greatly facilitates the
communication test;
1.3 Technical Specifications
[1] The HART interface can be configured as a primary master or the secondary master;
[2] The HART interface supports point-to-point mode and multi-drop mode;
[3] Supports one HART channel.
In point-to-point mode, the GT200-HT-MT supports burst communication.
In multi-drop mode, up to 13 HART instruments can be connected with an internal series resistor
(270Ω/2W), and up to 15 HART instruments with external series resistor (250Ω/3W);
[4] Supports all commands of the HART protocol;
[5] Each HART command can be configured to different outputting mode: change-of-state output, polling output,
initialization output or disable output;
