12.3.11 Error codes returned to request source during communication with CPU module
Table12.12 Error code
Error details
• Communication was made during system
switching.
• The system specified in the transfer setup
(request destination module I/O number)
does not exist.
The redundant system is not established.
(Control system/standby system or System A/
System B not yet definite)
The command that could not be processed
was executed when the transfer setup
(request destination module I/O number) is
Control system/Standby system/System A/
System B.
The command cannot be executed since
system switching is inhibited by the manual
switching enable flag (SM1592).
system
The specified command cannot be executed
during online program change operation.
The transfer setup or function unavailable for
the debug mode was used.
The control system/standby system specifying
method is not supported.
System switching was executed by the other
condition during execution of system switching
by GX Developer.
Sum check error occurred in tracking
communication.
The command cannot be executed in the
separate mode.
System switching was not executed since an
error occurred in the redundant system
compatible network module of the standby
system.
Corrective action
• Execute again after system switching.
• After checking whether the specified system exists or
not, restart communication.
• Normally start the system as the redundant system.
(Make communication again after establishing the
system.)
• Execute again after changing the transfer setup
(request destination module I/O number) to "No
settings have been made" (03FF
Execute again after changing the transfer setup (request
destination module I/O number) to "No settings have
been made" (03FF ).

Manual system switching is inhibited by the manual
switching enable flag (SM1592). Execute again
system
after turning ON SM1592.
Execute again after the online program change operation
is finished.
• Execute again after changing to the backup mode.
• Execute again after changing the transfer setup
(request destination module I/O number) to System A
or control system.
This function cannot be executed since it is not
supported.
Although system switching was executed from GX
Developer, system switching was executed first by the
other condition. Check the system for any problem and
execute the operation again as necessary.
Execute communication again after changing the
tracking cable.
If the same error recurs after the tracking cable is
changed, the cause is the hardware fault of the CPU
module.
(Please contact your local nearest Mitsubishi or
representative, explaining a detailed description of the
problem.)
Execute again after changing to the backup mode.
By monitoring SD1690 (other system network module
No. that issued system switching request), identify the
faulty redundant-compatible intelligent module of the
standby system, then remove the module fault, and
execute again.
