Bộ chuyển đổi Modbus TCP/IP sang HART ICP DAS HRT-711
The HRT-711 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 utility software for users to configure the HRT-711. By using this module, users can integrate their HART devices into Modbus network easily.
