Error codes related to the online module change function
The following table lists the codes of errors related to the online module change function.
The code of an error detected during online module change is stored in SD1618 (Online module change error code).
The code of an error when a disable request is executed during online module change is stored in SD1619 (Disable request
error code during online module change).
Error
code
Error name Error details and cause Action
4110H Online module change
error
The online module change function was executed
while the CPU module was in an error state (stop
error).
The module cannot be changed online. Power off the
programmable controller, and replace the module.
4111H In a multiple CPU system, the online module
change function was executed even though other
CPU modules have not started up.
Execute the function again after all the CPU modules in the
system start up.
4202H • An attempt was made to change two modules
directly at the same time.
• A module that is not ready to be removed was
removed.
• Continue processing for the module being changed online.
Two modules cannot be changed online at the same time.
For the other module, power off the programmable controller,
and replace the module.
• Turn on SM1602 (Module removal request flag) and check
that the value, 5, is stored in SD1617 (Online module change
progress status). Then, continue processing from the step for
mounting a module.
4205H The online module change function was executed
in a multiple CPU system where a CPU module that
does not support this function is included.
The module cannot be changed online. Power off the
programmable controller, and replace the module.
4206H An attempt was made to change the inter-module
synchronization target module online.
The module cannot be changed online. Power off the
programmable controller, and replace the module.
4210H The selected module is out of the valid range. Check and correct the target base unit number and/or slot
number, and turn on SM1600 (Module selection request flag)
again.
4214H The model of the newly-mounted module differs
from that of the module before online change. Or,
the newly-mounted module is not upward
compatible (module mismatch).
Mount the same model or the upward compatible module, and
execute the request again.
• Mount a module of the same model, and perform the module
recognition processing again.
4215H • The module recognition processing is performed
without the module being mounted.
• The module selection processing is performed to
the slot that is set as "Empty".
• The module newly-mounted to the system is not
mounted correctly.
• Mount a module, and perform the module recognition
processing again.
• Check and correct the target base unit number and/or slot
number, and turn on SM1600 (Module selection request flag)
again.
• Mount the module correctly.
4216H The module newly-mounted to the system online
has failed. (The CPU module cannot access to the
module.)
• The module has failed.
• The module newly-mounted to the system is not
mounted correctly.
Use another module, and execute the request again. Or, power
off the system, and replace the module with the one that
supports the online module change function.
• Replace the module with the normal one.
• Mount the module correctly.
4218H • The online change target module (before
change) does not support the online module
change function.
• The module newly-mounted to the system online
(after change) does not support the online
module change function.
• The online module change function was
executed to change the MELSEC-Q series
module.
• If an error occurs at the stage of selecting a module, the
module cannot be changed online. Power off the
programmable controller, and replace the module.
• If an error occurs at the stage of recognizing a module,
replace the module with the one that supports the online
module change function, and continue the processing.
• The module cannot be changed online. Power off the
programmable controller, and replace the module.
421AH The online module change function was executed
to change a module controlled by another CPU
module.
Execute the function from the control CPU module.
4222H The request cannot be executed because the
redundant function module is restarting.
Issue the request again after the restart of the redundant
function module has completed.
