Bits
11 through 15 of the RUN command (register 0001H) are not used. When writing the data, be sure to set
all
of these bits to 0. These bits when read are set to 0.

Registers
described “not used” may be used for internal processing. Do not write any data to such registers.
Communications with a Programmable Controller
The
RS-422A/485 communications of the 3G3RV Inverter conform to the MODBUS Communications Proto-
col.
This protocol cannot share the same line with any other communications protocol.
To
control the 3G3RV through RS-422A/485 communications with the Programmable Controller, mount a
Serial
Communications Board or Unit to the Programmable Controller and use the protocol macro function.
The
following settings and operations are necessary for serial communications using the protocol macro func-
tion.
• Configure
system settings for the Serial Communications Board or Unit
• Create
Send & Recv procedures conforming to the MODBUS Communications Protocol by means of pro-
tocol
macro tools (CX-Protocol or Protocol Support Tool), and transfer them to the Serial Communications
Board.
• Execute
the PMCR instruction on the CPU Unit of the Programmable Controller.
