1. Introduction

Modbus and HART are two kinds of famous protocols and used wildly in the fields of factory and

process automation. The HRT-710 / HRT-310 module is a Modbus to HART gateway. By using

this module, users can integrate their HART devices into Modbus network easily. The below

figure is the application of HRT-710 / HRT-310.

(Note : The below description of HRT-710 / HRT-310 will be HRT-7(3)10)

Figure 1: The application of HRT-710 / HRT-310

The below table are the difference between HRT-710 and HRT-310.

HRT-710 HRT-310

Din Rail Installation Horizontal Upright

HART Signal Standard Enhanced send/receive signal

(For long distance comm.)

Loop Power No Support

(module provides +30V output)

Built-In Resistor 250 Ohm (1/4W) 250 Ohm (1W)

[ Note ]

1. The software settings for HRT-710 and HRT-310 are all the same and HG_Tool can be used

for them.

The main features and specifications of HRT-7(3)10 are described as below.
