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.
