Error
Error and cause
code
[MULTI EXE. ERROR]
Either of the following settings was made in a
multiple CPU system.
• Multiple CPU automatic refresh setting was
made for the inapplicable CPU module.
• "I/O sharing when using multiple CPUs" setting
was made for the inapplicable CPU module.
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[MULTI EXE. ERROR]
The system configuration for using the multiple
CPU high speed transmission function is not met.
• The Universal model QCPU (except Q00UCPU,
7011
Q01UCPU, Q02UCPU) is not used for the CPU
No.1.
• The multiple CPU high speed main base unit
(Q3DB) is not used.
• Points other than 0 is set to the send range for
the CPU module incompatible with the multiple
CPU high speed transmission function.
• Points other than 0 are set to the auto refresh
send range for the multiple CPU high-speed
transmission area even though the CPU module
does not support the use of this area.
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[MULTI EXE. ERROR]
The Q172(H)CPU(N) or Q173(H)CPU(N) is
mounted to the CPU slot or slots 0 to 2. (This may
result in a module failure.)
7013 ■Collateral information
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[MULTI CPU ERROR]
In a multiple CPU system, an error occurred in the
CPU module where "All station stop by stop error
of CPU" was not selected in the operating mode
setting. (The CPU module where no error occurred
7020
was used to detect an error.)
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• Always
[CPU LAY ERROR]
An assignment error occurred in the CPU-
mountable slot (CPU slot, I/O slot 0, 1) in excess
of the number of CPU modules specified in the
multiple CPU setting of "PLC Parameter".
7030
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset

Corrective action
• Correct the multiple CPU automatic refresh
setting.
• Correct the "I/O sharing when using
multiple CPUs" setting.
• Change the system configuration to meet
the conditions for using the multiple CPU
high speed transmission function.
• When auto refresh is performed for the
multiple CPU high-speed transmission
area, set 0 point to the auto refresh send
range of the CPU module that does not
support the use of this area.
• Check the QCPU and Motion CPU that can
be used in a multiple CPU system, and
change the system configuration.
• Remove the Motion CPU incompatible with
the multiple CPU system.
Read the common information of the error
using the programming tool. Check the error
in the CPU module, and eliminate the error
cause.
• Set the same value to the number of CPU
modules specified in the multiple CPU
setting of "PLC Parameter" and the number
of mounted CPU modules (including CPU
(empty)).
• Make the type specified in the I/O
assignment setting of "PLC Parameter"
consistent with the CPU module
configuration.
