36 ERROR CODES
36.4 List of Error Codes
406BH Online registration error • Online operation was interrupted due to a CPU
module error.
• Check the status of the CPU module by executing the
module diagnostics.
Identify the error, and take a corrective action referring to the
troubleshooting section.
406CH Online registration error • The number of functions that can be executed
simultaneously exceeds the limit.
• Execute again after stopping the functions that are executed
in another engineering tool.
406DH Online registration error • The operation cannot be performed because the
operation is performed from the same activation
source.
• Execute again after the operation from the same activation
source has completed.
406EH Online registration error • The specified operation cannot be maintained. • Check and correct the operation.
4070H Verification error • The program not yet corrected and the one
corrected by online program change are different.
• The execution program that was written to the
programmable controller (including online
change) or the execution program that was
written by using online change operation differs
from the program restoration information to be
written.
• Read the program from the CPU module to match it with that
of the engineering tool, and then execute the online program
change again.
• Write the program including the program restoration
information to the programmable controller (including online
change), or execute online change.
4080H Any other error • Request data error
■When CPU Module Logging Configuration Tool is
used
• Request or setting data error
• Check the request data that has been specified.
■When CPU Module Logging Configuration Tool is used
• Check the specified data, and write it to the CPU module
again.
4081H Any other error • The search target data cannot be detected. • Check the data to be searched.
4082H Any other error • The specified command cannot be executed
because it is being executed.
• Execute the command again after the processing of the
command from another engineering tool ends.
4083H Any other error • An attempt was made to perform operation to the
program not registered in parameter.
■When CPU Module Logging Configuration Tool is
used
• The data logging specifying the program that is
stored in the CPU module but not registered in
the CPU parameters was started.
• Register the program in parameter.
4084H Any other error • The specified pointer (P or I) does not exist. • Check if the pointer (P or I) exist in the data.
4085H Any other error • The pointer (P or I) cannot be specified because
the program is not specified in parameter.
• Register the program to be executed in parameter first, and
specify the pointer (P or I).
4086H Any other error • The specified pointer (P or I) has already been
added.
• Check and correct the pointer number to be added.
4087H Any other error • The number of pointers (P or I) exceeds its limit. • Check and correct the specified pointer (P or I).
4088H Any other error • The specified step number is not at the head of
the instruction.
• The program differs from that stored in the CPU
module.
■When CPU Module Logging Configuration Tool is
used
• The data logging specifying the step number that
does not exist or is not specified as the start
number of the instruction was started.
• Check and correct the specified step number.
• Read the program from the CPU module to match it with that
of the engineering tool, and then execute the online program
change again.
4089H Any other error • An attempt was made to insert/delete the END
instruction by online program change.
• Check the specified program file contents.
• Set the operating status of the CPU module to STOP, and
write the program.
408AH Any other error • The file capacity exceeded after the online
change was executed.
• Check the capacity of the specified program file.
• Set the operating status of the CPU module to STOP, and
write the program.
408BH Any other error • The remote request cannot be executed. • Change the status of the CPU module so that the remote
request can be executed, and execute the request again.
• For remote operation, set the parameter to "Enable remote
reset".
408DH Any other error • The instruction code that cannot be handled
exists.
• Check whether the model of the used CPU module is correct
or not.
• The program where online change was attempted includes
the instruction that cannot be handled by the CPU module
specified for the project. Check the program and delete the
instruction.
