[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
7011
CPU high speed transmission function is not met.
• The QnUCPU 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 is set to the send range for the
CPU module incompatible with the multiple CPU.
■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 was
7020
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 the PLC parameter dialog
7030 box.
■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.
• Set the send range of CPU, that does not
correspond to multiple CPU compatible area, at
0 point, when performing automatic refreshing in
multiple CPU compatible 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 individual information of the error using
the programming tool. Check the error in the CPU
module, 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.
