Appendix 3 Error Code
Error details and cause
• The number of writes to the data memory
exceeded 20,000 times.
• Low battery voltage was detected. An
error was also detected in a battery
latched (backed) device.
• Writing failed because the write protect
switch of the memory card is enabled
(writing is prohibited).
• Overlapping IP addresses were
detected.
• An annunciator that was turned ON by
the SET F instruction or OUT F
instruction was detected.
• The channel specified by instructions
using communication functions or built-in
I/O is already used by other instructions.
• The number of times that applied
instructions are used in the program
exceeded the specified limit.
• Writing during RUN (change or deletion)
is performed on an instruction being
executed.
• Writing during RUN (change or deletion)
is performed on an instruction being
executed.
• Writing during RUN (change or deletion)
is performed on an instruction being
executed.
• Writing during RUN (change or deletion)
is performed on an instruction being
executed.
Action
• Replace the CPU module.
• Check the connection of the battery.
• Replace the battery as soon as possible.
• Disable the write protect switch of the
memory card.
• Check the IP address.
• Check the program of that number
(annunciator number).
• Verify that the channel specified by
instructions using communication functions
or built-in I/O is not used by other
instructions.
• Verify that the number of times that applied
instructions are used in the program does
not exceed the specified limit.
• Verify that the writing during RUN (change or
deletion) is performed on an instruction
being executed.
• E If the writing is executed during an ongoing
RUN, after confirming that the pulse output
is not occurring, turn OFF  ON the driving
contact point to start the operation of the
positioning instruction.
• Verify that the writing during RUN (change or
deletion) is performed on an instruction
being executed.
• E If the writing is executed during an ongoing
RUN, after confirming that the pulse output
is not occurring, turn OFF  ON the driving
contact point to start the operation of the
positioning instruction.
• Verify that the writing during RUN (change or
deletion) is performed on an instruction
being executed.
• E If the writing is executed during an ongoing
RUN, after confirming that the pulse output
is not occurring, turn OFF  ON the driving
contact point to start the operation of the
positioning instruction.
• Verify that the writing during RUN (change or
deletion) is performed on an instruction
being executed.
• E If the writing is executed during an ongoing
RUN, after confirming that the pulse output
is not occurring, turn OFF Ю ON the driving
contact point to start the operation of the
positioning instruction.
