Error Contents and Cause
Code
[CPU LAY ERROR]
An assignment error occurred within the range of
the number of CPUs specified in the multiple CPU
setting of the PLC parameter dialog box.
7031
■Collateral information
• Common information: Module No. (CPU No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[CPU LAY ERROR]
The number of CPU modules mounted in a
multiple CPU system is wrong.
■Collateral information
7032
• Common information: Module No. (CPU No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[CPU LAY ERROR]
The CPU module has been mounted on the
inapplicable slot.
■Collateral information
7035
• Common information: Module No. (Slot No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[CPU LAY ERROR]
The host CPU No. set by the multiple CPU setting
and the host CPU No. determined by the mounting
position of the CPU module are not the same.
7036 ■Collateral information
• Common information: Module No. (CPU No.)
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[INCORRECT FILE]
The error of stored file (enabled parameter file) is
detected.
■Collateral information
• Common information:-
8031
• Individual information: File diagnostic
information
■Diagnostic Timing
• At power-on/At reset/STOP→RUN/At writing to
programmable controller
[F**** ]
Annunciator (F) turned on.
(The "****" portion of the error message indicates
an annunciator number.)
9000
■Collateral information
• Common information: Program error location
• Individual information: Annunciator number
■Diagnostic Timing
• When instruction executed
• 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 system so that the number of
mountable modules of each CPU module does not
exceed the maximum number of mountable
modules specified in the specification.
• Mount the CPU module on the applicable slot.
• Remove the CPU module from the slot where a
CPU module cannot be mounted.
• Mount the mounting slot of the CPU module
correctly.
• Correct the host CPU No. set by the multiple
CPU setting to the CPU No. determined by the
mounting position of the CPU module.
Write the files shown in SD17 to SD22 (individual
information) to the drive shown in SD16 (L)
(individual information). Turn off and then on or
reset the CPU module.
If the same error code is displayed again, the
cause is a hardware failure of the CPU module.
(Please consult your local Mitsubishi
representative, explaining a detailed description of
the problem.)
*24*30
Read the individual information of the error using
the programming tool to identify the numeric value
(annunciator number). Check the program
corresponding to the value.
