(4) Writing to the program memory during online change and TC setting value
change
Due to automatic data transfer to the program memory, the time takes to write data to the CPU module during the
RUN status and to change TC setting value extends by the time shown in the following table.

Since the number of writes to the program memory (Flash ROM) is limited (up to 100,000 times), set the
automatic transfer to the program memory to be disabled when data are written to the CPU module in the RUN
status and changing TC setting value frequently.
