Note 1. Transmission and reception by specifying the serial communications port of the serial communi-
cations board are enabled in the CS1D-CPU@@SA with unit version 4.0 or later.
2. In the CS1D CPU Units (for Duplex-CPU Systems), transmission and reception by specifying the
serial communications port of the serial communications board cannot be used.

Fun
Function
code
222 Reads the contents of memory
area of a Special I/O Unit or CPU
Bus Unit.
223 Outputs the contents of the CPU
Unit's I/O memory area to a Spe-
cial I/O Unit or CPU Bus Unit.
260 Starts a communications
sequence (protocol data) that is
registered in a Serial Communica-
tions Board (CS Series only) or
Serial Communications Unit.
236 Outputs the specified number of
bytes of data from the CPU Unit's
built-in RS-232C port or one of
the Serial Communications
Board's serial ports. (The Serial
Communications Board must be
Ver. 1.2 or later).
235 Reads the specified number of
bytes of data from the CPU Unit's
built-in RS-232C port or one of
the Serial Communications
Board's serial ports. (The Serial
Communications Board must be
Ver. 1.2 or later).
256 Outputs the specified number of
bytes of data from one of the Serial
Communications Unit's serial ports.
(The Serial Communications Unit
must be Ver. 1.2 or later).
255 Reads the specified number of
bytes of data from one of the Serial
Communications Unit's serial ports.
(The Serial Communications Unit
must be Ver. 1.2 or later).
262 Outputs the specified number of
bytes of data from the serial port
of a CJ1W-
SCU22/SCU32/SCU42 Serial
Communications Unit. The data is
output in no-protocol mode from
the specified first word with the
start code and end code (if any)
specified in the allocated DM
Setup Area.
This instruction sends the data to
the Serial Communications Unit
as soon as the instruction is exe-
cuted to achieve high-speed data
transmission.
261 Reads the specified number of
bytes of data from the serial port
of a CJ1W-
SCU22/SCU32/SCU42 Serial
Communications Unit to CPU Unit
memory starting at the specified
first word. The data is read in no-
protocol mode with the start code
and end code (if any) specified in
the allocated DM Setup Area.
This instruction reads the data
from the Serial Communications
Unit as soon as the instruction is
executed to achieve high-speed
data reception.
237 Changes the communications
parameters of a serial port on the
CPU Unit, Serial Communications
Board (CS Series only), or Serial
Communications Unit (CPU Bus
Unit).
264 Starts a communications
sequence (protocol data) that is
registered in a Serial Communica-
tions Unit.
