Error 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 the redundant system.)
6112
■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 communication hardware of the
CPU module was faulty, the CPU module could
not communicate with the other system through
6120
the tracking 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 tracking communication hardware of the
CPU module became faulty.

(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.

(This can be detected from the control system or
standby system of the redundant system.)

Corrective action
Switch to the file registers of which capacity is
greater than the file registers specified in the
tracking settings.
Connect a tracking cable and start up the
module. If the same error occurs, the cause is
a failure of the tracking cable or the tracking
communication hardware of the CPU module.
Please consult your local Mitsubishi
representative.
• If the tracking cable was removed, connect
the tracking cable to the connectors of the
CPU modules of the two systems.
• If the error remains even after the above
action is taken, the cause is a failure of the
tracking cable or the tracking
communication hardware of the CPU
module. Please consult your local
Mitsubishi representative.
• Power off and on or reset the CPU module
that detects the error. If the same error
occurs, the cause is a hardware failure of
the CPU module. Please consult your local
Mitsubishi representative.
• Confirm the redundant system startup
procedure, and execute a startup again.
