Meaning Corrective action
Check the specified station.
Check the communication module or CPU.
Check the special function module at the specified
address.
Specify a step number (address) within the parameter
range.
Cancel the remote RUN/STOP from the other
module.
Check the MELSECNET (II).
Check to see if the special function module has failed.
Check the CPU.
Check to see if there is a CPU error.
Check to see if there is a CPU error.
Check the contents of the control table.
Increase the data storage area.
The specified processing cannot be performed in the
applicable CPU.
Specify the correct device code.
Specify a device number in the allowable range.
Monitor after performing monitor registration.
Use the same PC number as at the time of monitor
registration.
Use the same system configuration as at the time of
monitor registration.
Decrease the number of monitoring points.
Change to extension file registers where the
execution is possible.
Do not change programs or parameters while the
ROM is operating.
Perform the processing after stopping the CPU.
Specify the processing code correctly.
Check the detailed error code using the format 2
control table of the PCRD/PCWT instruction. See the
manual for the CPU that was accessed or the CPU
that was routed through prior to the accessed CPU
for the meaning and corrective action for the detailed
error code.
Check the detailed error code using the format 2
control table of the PCRD/PCWT instruction. See the
error code table in Appendix for the meaning and
corrective action for the detailed error code.
Check the detailed error code using the format 2
control table of the PCRD/PCWT instruction. See the
manual for the Ethernet module that was routed
through prior to the access target for the meaning and
corrective action for the detailed error code.
Check the detailed error code using the format 2
control table of the PCRD/PCWT instruction. See the
manual for the network module that was routed
through prior to the access target for the meaning and
corrective action for the detailed error code.
