Error Contents and Cause
Code
[TRK. SIZE ERROR]
File registers greater than those of the standby
system were tracked and transmitted from the
control system.
(This can be detected from the standby system of
6112
the redundant system.)
■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• When an END instruction executed
[TRK. CABLE ERR.]
• A start was made without the tracking cable
being connected.
• A start was made with the tracking cable faulty.
• As the tracking hardware on the CPU module
side was faulty, communication with the other
system could not be made via the tracking
6120
cable.
(This can be detected from the control system or
standby system of the redundant system.)
■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[TRK. DISCONNECT]
• The tracking cable was removed.
• The tracking cable became faulty while the CPU
module is running.
• The CPU module side tracking hardware
became faulty.
6130 (This can be detected from the control system or
standby system of the redundant system.)
■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• Always
[TRK.INIT. ERROR]
• The other system did not respond during initial
communication at power-on/reset.
• The error occurred at a startup since the
redundant system startup procedure was not
followed.
6140
(This can be detected from the control system or
standby system of the redundant system.)
■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[CONTROL EXE.]
The standby system has been switched to the
control system in a redundant system. (Detected
by the CPU that was switched from the standby
system to the control system.)
Since this error code does not indicate the error
information of the CPU module but indicates its
status, the error code and error information are not
stored into SD0 to 26, but are stored into the error
6200
log every system switching.
(To check the error information, obtain the error log
using the programming tool.)
■Collateral information
• Common information: Reason(s) for system
switching
• Individual information:-
■Diagnostic Timing
• Always
Corrective Action
Switch to the file registers of which capacity is
greater than the file registers specified in the
tracking settings.
Make a start after connecting the tracking cable. If
the same error still occurs, this indicates the
tracking cable or CPU module side tracking
transmission hardware is faulty.
(Please consult your local Mitsubishi
representative, explaining a detailed description of
the problem.)
• If the tracking cable was removed, connect the
tracking cable to the connectors of the CPU
modules of the two systems.
• When the error is not resolved after connecting
the tracking cable to the connectors of the CPU
modules of the two systems and resetting the
error, the tracking cable or CPU module side
tracking hardware is faulty.
(Please consult your local Mitsubishi
representative, explaining a detailed description of
the problem.)
• Power off and then on or reset the CPU module
where the error occurred. 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.
