Features

The HRT-310 is designed to be used as a master device of HART protocol, allowing the Modbus to connect HART devices and converting the HART protocol to Modbus RTU / ASCII protocol. In addition, the gateway is equipped with a more powerful built-in resistor, allowing connecting up to 15 HART devices without having to connect an additional external resistor. The HRT-310 is designed for users to integrate their HART devices into Modbus network easily and quickly.

Applications

  • Industrial Automation
  • Factory Automation
  • Process Automation
  • Etc…

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-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.
