Error
Code Error Contents and Cause
*1
(SD0)
Either of the following settings was
made in a multiple CPU system.
• Multiple CPU automatic refresh
setting was made for the inapplicable
7011
CPU module.
• "I/O sharing when using multiple
CPUs" setting was made for the
inapplicable CPU module.
In the operating mode of a multiple
CPU system, an error occurred in the
CPU where "system stop" was not
7020
selected.
(The CPU module where no error
occurred was used to detect an error.)
An assignment error occurred in the
CPU-mountable slot (CPU slot, I/O slot
0, 1) in excess of the number of CPU
7030
modules specified in the multiple CPU
setting of the PLC parameter dialog
box.
An assignment error occurred within
the range of the number of CPUs
7031
specified in the multiple CPU setting of
the PLC parameter dialog box.
• The number of CPU modules
mounted in a multiple CPU system is
wrong.
(Q00CPU or Q01CPU: more than 1
module, motion CPU: more than 1
7032 module, PC CPU module: more than
1 module)
• The PLC CPU is mounted as the
CPU No. 2 or later.
• The motion CPU is mounted as the
CPU No. 3.
The CPU module has been mounted
7035
on the inapplicable slot.
*1 : Characters in parentheses ( ) indicate the special register numbers where individual information is being
stored.
*12 : This applies to the CPU module of function version B or later.

Corrective Action
• Correct the multiple CPU automatic
refresh setting.
• Correct the "I/O sharing when using
multiple CPUs" setting.
Read the individual information of the
error using the peripheral device,
check the error of the CPU module
resulting in CPU module fault, and
remove the error.
• Set the same value to the number of
CPU modules specified in the
multiple CPU setting of the PLC
parameter dialog box and the
number of mounted CPU modules
(including CPU (empty)).
• Make the type specified in the I/O
assignment setting of the PLC
parameter dialog box consistent with
the CPU module configuration.
Configure a multiple CPU system so
that the following restriction will be
satisfied:
Q00CPU or Q01CPU: within 1 module
the motion CPU: within 1 module PC
CPU module: within 1 module.
Mount the CPU module on the
applicable slot.
