Bộ chuyển đổi Modbus RTU/ASCII sang HART ICP DAS HRT-310
The HRT-710 / HRT-310 Gateway is specially designed for the master dhfdhjnjuevice 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.

HRT-710 / HRT-310, a HART master to Modbus slave gateway, is applied to integrate the information from these HART flow meters into the customer’s HMI system. Through the HRT-710 / HRT-310, all of the HART flow meters will be regarded as Modbus slave devices and the HMI system can use the built-in Modbus RTU communication to access these HART flow meters easily.

More than 250 HART device information needs to be integrated to surveillance center. In PC side, uses 3 pieces of PCI cards (VXC-148U, for 24 channels RS-485 expansion). I-2542A and I-2542B (RS-485 to Fiber) are used in every RS-485 channel to extend RS-485 communication distance. There are about 20 pieces of HRT-710 modules used in every RS-485 channel with the different station ID. Through the structure, SCADA or HMI system can integrate all HART device information via Modbus protocol easily and quickly.
