    Modbus and HART are two kinds of famous protocols and used wildly in the fields of factory and process automation. The HRT-711 module is a Modbus to HART gateway. By using this module, users can integrate their HART devices into Modbus network easily. The below figure 1 shows an application example for the HRT-711 module.

    In this section, this user’s manual will introduce the wiring for each interface. 2.3.1 RS-232 The RS-232 port of HRT-711 uses a 3-wire communication interface. It needs a unique cable, CA-0910, to wire from screwed terminal block to D-Sub 9pin connector. Users can choose use CA-0910 for RS-232 wiring or directly connecting to D-Sub.

    When the HRT-711 module is started, it will perform the Initial mode first and then the Operation mode. (1) When HRT-711 runs in Initial mode, it will execute all initial command and the HART led will flash. (2) When HRT-711 runs in Operation mode, it will execute all polling command automatically and the HART led will always on.
