The programs, parameters, symbols and positions are read from the flash memory at restart. The data in
the main CPU memory will remain the same as the original data before edit unless the edited data are
written to the flash memory.
The controller always operates in accordance with the data in the main CPU memory (excluding the
parameters).
Note: SEL global data cannot be retained if the backup battery is not installed.
