POINT
(1) Save the parameters in the buffer memory to a flash ROM. Otherwise, they are
cleared when the power is turned off or the CPU module is reset.
(2) Since the number of writes to flash ROM is limited, use Request for Saving
Parameters to Flash ROM (Y17) only when creating or changing parameters.
