Error details
The redundant system is not established.
(Control system/standby system or System
A/System B not yet definite)
A command that cannot be processed was
executed when the control system or standby
system is specified in the transfer setup (request
destination module I/O number).
The command cannot be executed since system
switching is inhibited by the manual system
switching enable flag (SM1592).
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 the programming tool.
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.
Since a communication error or system switching
occurred during online program change to the
control system CPU module, online program
change to the standby CPU module cannot be
executed.
Corrective action
• 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 the operation again after changing the
transfer setup (request destination module I/O
number) to No settings have been made
(03FF )/system A/system B.
H
Manual system switching is inhibited by the
manual system switching enable flag (SM1592).
Execute again 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 the
programming tool, 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 occurs even after the tracking
cable is changed, the cause is a hardware failure
of the CPU module. Please consult your local
Mitsubishi representative.
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.
Since a communication error or system switching
occurred during execution of online program
change to the control system CPU module, online
program change redundant tracking was
suspended.
Execute online program change again after
confirming that communication with the control
system CPU module and standby system CPU
module can be normally made.
If it takes time for the communication between the
programming tool and either the control system
CPU module or standby system CPU module,
change the value in SD1710 (standby system
online start waiting time) so that errors may be
avoided.
