Operation
12. “SYSTEM” mode
12.1.4.2 Serial I/O setting
For serial I/O boards (CC-Link/DeviceNet/PROFIBUS), there are 3 parameters (4
parameters for DeviceNet only) to be set, including the parameter to enable or disable the
serial I/O unit monitor.
1.

3.
4.
Parameter
Board condition
Remote cmd / IO cmd
(SI05)
Output MSG to SOW(1)
IO size
(DeviceNet only)
Meaning
Enables or disables the serial I/O board. When set to "VALID" the
serial I/O can be used. When set to "INVALID" the serial I/O
cannot be used.
Enables or disables the functions of remote commands and I/O
commands using word information and bit information. When set
to "VALID" the remote commands and I/O commands can be used.
When set to "INVALID" the remote commands and I/O commands
cannot be used.
This parameter cannot be set to "VALID" simultaneously with
parameter 3.
When parameter 4 is set to "Small", the remote command cannot
be used, although this parameter can be set to "VALID". (The I/O
commands can be used, but use of them is limited partly.)
Enables or disables the function that sends a message number,
which is displayed on the MPB, to word information SOW(1).
When set to "VALID" the message number to be displayed on the
MPB will be output. When set to "INVALID" the message number
to be displayed on the MPB will not be output. This parameter
cannot be set to "VALID" simultaneously with parameter 2. Also,
this parameter cannot be set to "VALID" when parameter 4 is set to
"Small".
Selects the number of channels occupied by the DeviceNet
compatible module, from "Large" or "Small". (Default setting:
Large)
When set to "Large", 24 channels each are occupied by the
input/output. When set to "Small", 2 channels each are occupied by
the input/output.
This parameter cannot be set to "Small" when parameter 3 is set to
"VALID".

NOTE
• Set the Board status parameter to
"INVALID" when not using serial
I/O boards.
• When the Board status parameter
is set to "INVALID", the dedicated
input/output of the STD.DIO
connector is enabled. When the
Board status parameter is set to
"VALID", the dedicated input
(except DI1) of the STD.DIO
connector is disabled.
• For remote commands and I/O
commands, refer to the command
reference manual.
• For a description of codes issued
from the message output function
for SOW(1), refer to "1. Error
Messages" in chapter 9.
• When the Remote command & I/O
command parameter is set to
"VALID", the Output MSG to
SOW(1) parameter cannot be set
to "VALID". Likewise, when the
Output MSG to SOW(1) parameter
is set to "VALID", the Remote
command & I/O command
parameter cannot be set to
"VALID".
• The "4. IO size" parameter is
supported by controllers with a
DeviceNet board installed and
from Ver. 9.08 onwards. Earlier
version controllers do not have the
"4. IO size" parameter, so the
number of occupied channels is
the same as the "Large" IO size
setting.
• When the IO size is set to “Small”
(2CH each of input/output), the I/
O commands can be used but the
remote commands cannot be used.
Note that use of the I/O commands
is partly limited.
• When the IO size is set to “Small”
(2CH each of input/output), the
“Output MSG to SOW(1)”
parameter function cannot be
used.
