7-9 Communications with Programmable Controller
The Communications Board can be mounted to OMRON’s SYSMAC CS/CJ-series or
C200HX/HG/HE CPU Unit. The Inverter can then be controlled by the Communications
Board through its RS-422/485 port.
The communications protocol can be set by using the protocol macro function. There-
fore, there is no need to write a ladder program for the communications protocol when
the function is used.
The following description provides information on how to control the Inverter through
communications with the SYSMAC CS/CJ-series or C200HX/HG/HE Communications
Board by using the protocol macro function.
The RS-422/485 communications of the 3G3MV Inverter conform to the MODBUS
Communications Protocol and this protocol cannot be used together with DeviceNet
communications protocol or any other communications protocol. Only 3G3MV-series
Units can be connected as Slaves.

tion.)

• The following Communications Boards are needed to use the RS-422/485 communications port.
Note The RS-232C port can be used if an RS-422/485 conversion adapter is installed. For ease of wir-
ing, however, it is recommended that the RS-422/485 port be used. The following information is
for the RS-422/485 port.
