Error Contents and Cause
Code
6311 [CONTROL SYS. DOWN]
• As consistency check data has not transmitted
from the control system in a redundant system,
the other system cannot start as a standby
system.
• The error occurred at a startup since the
redundant system startup procedure was not
followed.
6312
(This can be detected from the standby system of
the redundant system.)
■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[CONTROL SYS. DOWN]
The control system detected the error of the
system configuration and informed it to the
standby system (host system) in the redundant
system.
6313
■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[PRG. MEM. CLEAR]
The memory copy from control system to standby
system was executed, and the program memory
was cleared.
■Collateral information
6400
• Common information:-
• Individual information:-
■Diagnostic Timing
• At execution of the memory copy from control
system to standby system
[MEM. COPY EXE.]
The memory copy from control system to standby
system was executed.
(This can be detected from the control system of
the redundant system.)
6410 ■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At execution of the memory copy from control
system to standby system
[TRK. PARA. ERROR]
The file register file specified in the tracking setting
of the PLC parameter dialog box does not exist.
■Collateral information
6500
• Common information: File name/Drive name
• Individual information: Parameter number
■Diagnostic Timing
• At power-on/At reset
[TRK. PARA. ERROR]
The file register range specified in the device detail
setting of the tracking setting of the PLC parameter
dialog box exceeded the specified file register file
capacity.
6501
■Collateral information
• Common information: File name/Drive name
• Individual information: Parameter number
■Diagnostic Timing
• At power-on/At reset
*15 This applies when the first five digits of the serial number of the CPU module is "09102" or later.
Corrective Action
• Replace the tracking cable. If the same error still
occurs, this indicates the CPU module is faulty.
(Please consult your local Mitsubishi
representative, explaining a detailed description
of the problem.)
• Confirm the redundant system startup
procedure, and execute a startup again.
Restart the system after checking that the
connection between base unit and the system
configuration (type/number/parameter of module)
are correct.
After the memory copy from the control system to
the standby system is completed, turn off and then
on or reset the system.

Read the individual information of the error using
the programming tool. Check the drive name and
file name and correct them.
Read the individual information of the error using
