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 ash memory is unchanged. As a result, the contents of the RAM does not match those of the ash
memory and the RUN/MEM LED blinks to prompt the user to transfer the contents of the RAM to the ash memory.
After rewriting the program, be sure to transfer the contents of the RAM to the ash memory. When the transfer is
completed normally, the RUN/MEM LED turns OFF.
<Method 1>
Perform transfer by using the loader.
<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 ash memory.
