Appendix 1 Error Codes

A
42B9H Safety related
error • The Safety CPU received a request from an unsupported
device.
• Send the request to the Safety CPU again from a supported
device.
42BAH Safety related
error • An SD memory card was specified for the write destination
for the safety sequence program, safety FB file, safety CPU
parameters, safety module parameters, safety global label
setting file, and standard/safety shared label setting file.
• Try the write operation again.
42BBH Safety related
error • The maximum capacity for safety programs and safety FB
files that can be stored in the specified drive (memory) has
been exceeding.
• Delete the safety programs or safety FB files stored in the
Safety CPU drive (memory), and execute again.
• Execute again after formatting Safety CPU drive (memory).
• Reduce the safety program and safety FB file to be written to
less than 40K steps and execute again.
42BCH Safety related
error • A file mismatch has been detected between the CPU
module and the safety function module/SIL2 function
module.
• Check that the safety function module or SIL2 function
module is mounted and format the memory. Write all files to
the CPU module. Then, reset and run the CPU module and
perform the processing again.
42BEH Safety related
error • The number of safety sequence programs, safety FB files,
safety CPU parameters, safety module parameters, safety
global label setting files, and standard/safety shared label
setting files exceeded the maximum number of files that can
be stored on the specified drive (memory).
• Execute again after deleting the safety sequence programs,
safety FB files, safety CPU parameters, safety module
parameters, safety global label setting files, and standard/
safety shared label setting files on the drive (memory).
42BFH Safety related
error • Initialization of the CPU module has been completed, but the
safety function module/SIL2 function module has not been
able to be initialized.
• To initialize the safety function module/SIL2 function module,
mount the each module to the right of the CPU module.
Power on and reset the CPU module. Then, initialize the
each module again.
42C0H Redundant
system related
error • An attempt was made to write an SFC program to the CPU
module set to redundant mode by executing the online
program change function.
• Check that an SFC program is not written to the CPU
module set to redundant mode.
42C1H Redundant
system related
error • Since the operation mode is changed or the systems were
switched during the initial processing or the initial processing
(when switched to RUN), it takes time to complete the
processing.
• Check whether the processing ends or not after a while.
• Take measures to reduce noise.
• If the same error code is displayed again even after the
redundant system is restarted, the possible cause is a
hardware failure of the CPU module, redundant function
module, or tracking cable. Please consult your local
Mitsubishi representative.
42C2H Redundant
system related
error • The memory copy function is executed to the CPU module
that does not support the selection writing of program
restoration information while no program restoration
information is in the CPU module of the control system.
• Execute the memory copy after the program restoration
information is written to the CPU module of the control
system.
• Replace the CPU module of the control system with the one
that supports the selection writing of program restoration
information.
42DEH Redundant
system related
error • The request cannot be executed because the safety
operation modes of two CPU modules differ between the
control system and standby system.
• Match the safety operation modes of two CPU modules
between the control system and standby system, and
execute the request again.
42DFH Redundant
system related
error • The request cannot be executed because an error has been
detected in the communications between the CPU modules
of the control system and the standby system.
• Check if the tracking cables have been properly connected.
If the same error code is displayed again even after the
tracking cables are connected properly, the possible cause
is a hardware failure of the CPU module, SIL2 function
module, redundant function module, or tracking cable.
Please consult your local Mitsubishi representative.
42F0H Safety related
error • The request cannot be executed because the safety
operation mode change is in progress.
• Execute the request again after completion of the safety
operation mode change that is currently in progress.
42F3H Safety related
error • The request cannot be executed because the safety function
module or SIL2 function module cannot be accessed.
• Check that the safety function module or SIL2 function
module is mounted and execute the request again.
• Check that the safety function module or SIL2 function
module operates normally and execute the request again.
42F4H Safety related
error Initialization of the CPU module has been completed, but the
safety function module cannot be initialized. To initialize the safety function module, mount it on the main
base unit. After power on the system and reset the CPU
module, initialize the safety function module again,
4300H Security function
error (user
authentication) • An operation requiring authentication was executed when no
authentication was received from the CPU module.
• An operation requiring authentication was executed from a
startup source or function that does not support user
authentication.
• Log in to the CPU module.
• Perform operation from a device which supports the user
authentication function.
