Error
Code Error Contents and Cause
(SD0)
• The tracking cable was removed.
• The tracking cable became faulty
while the CPU module is running.
• The CPU module side tracking
6130
hardware became faulty.
(This can be detected from the control
system or standby system of the
redundant system.)
• The other system did not respond
during initial communication at power
ON/reset.
• The error occurred at a startup since
6140 the redundant system startup
procedure was not followed.
(This can be detected from the control
system or standby system of the
redundant system.)
The standby system in a redundant
system is switched to the control
system.
(This can be detected from the standby
system of the redundant system.)
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
6200
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
log every system switching.
(Check the error information by reading
the error log using GX Developer.)
*1 The module whose first 5 digits of serial No. is 09012 or later.
Corrective Action
• 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.
(Contact your local Mitsubishi
representative, explaining a detailed
description of the problem.)
• Power the corresponding CPU
module OFF and then ON again, or
reset it and then unreset. If the same
error still occurs, this indicates the
CPU module is faulty. (Contact your
local Mitsubishi representative,
explaining a detailed description of
the problem.)
• Confirm the redundant system startup
procedure, and execute a startup
again.
Check the control system condition.
