12. "SYSTEM" mode
12.1.5.2 Serial IO setting
Make the serial IO option board setting as explained below.

NOTE
• Emergency stop ready signal (DI00), interlock input (DI11) and service
mode input (DI02) on the SAFETY connector are enabled even when the
serial IO is enabled.
• For detailed information on the remote commands and IO commands,
refer to the separate manual for controller options.
Parameter Meaning
1 Serial IO
Sets whether to use the serial IO. When set to "VALID",
the serial I/O can be used and dedicated inputs to SI0()
and SI1() are enabled. Dedicated inputs to parallel DIO
option are disabled.
2
Remote cmd/IO cmd
(SI05)
Sets whether to use the functions of remote commands
and I/O commands. When set to "VALID", the remote
commands (using word information) and I/O commands
(using bit information) can 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.)
3
Output MSG to
SOW(1)
Sets whether to output an error number to word
information SOW(1).
When set to "VALID", the error number will be output to
SOW(1) if an error occurs.
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".
4
IO size
(DeviceNet only)
Selects the number of channels occupied by a
DeviceNet unit from "Large" (input 24CH / output 24CH)
or "Small" (input 2CH / output 2CH).
The default setting is "Large".
The IO size cannot be set to "Small" when parameter 3
above is set to "VALID".
Parameter 3 cannot be set to "VALID" when the IO size
is set to "Small".
n
NOTE
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.
