4) Notes on rewriting programs
When rewriting the program in the main unit from the loader while the PLC is running, the built-in RAM is changed, however,
the built-in flash memory is unchanged. As a result, the contents of the RAM does not match those of the flash memory, and
the RUN/MEM LED blinks to prompt the user to transfer the contents of the RAM to the flash memory.
After rewriting the program, be sure to transfer the contents of the RAM to the flash memory. When the transfer is completed
normally, the RUN/MEM LED turns OFF.
<Method 1>
By using the loader, transfer the contents of the RAM to the flash memory.
<Method 2>
After rewriting the program, turn OFF the main unit and then ON again. When the power supply is turned ON, the contents
of the RAM is automatically transferred to the flash memory.
