The HRT-710 / HRT-310 Gateway is specially designed for the master device of HART protocol. It allows the Modbus master to access the HART devices. These HART devices may be a transmitter, an actuator and so forth. In addition, we also provide the software utility, HG_Tool, for module configuration and HART device diagnosis. By using these modules, users can integrate their HART devices into Modbus network easily and quickly.
