4) Power on the CPU module.
Boot the files in the memory card to the program memory.
After boot operation, write the program memory data to the standard ROM.
5) After automatic write to standard ROM, the BOOT LED and ERR. LED start flashing and the CPU module
enters stop error status.
6) Power off the CPU module.
7) Remove the memory card and set the parameter-valid drive with the DIP switches on the CPU module to
the standard ROM.

8) Powering on the CPU module starts boot operation from the standard ROM to the program memory and can
start actual operation.
(4) Precautions
The following describes precautions for automatic write to standard ROM.
(a) When a file with the same name exists in the program memory
When the program memory has a file whose name is the same as that of the one to be booted from the
memory card, the file is overwritten by the data in the memory card.
When the program memory does not have the same file name, the file to be booted from the memory card is
added to the program memory.
If the program memory capacity is exceeded then, "FILE SET ERROR" (error code: 2401) is detected.
(b) Program memory clear at boot operation
Whether files are booted after program memory clear or booted without program memory clear can be
selected.
For automatic write to standard ROM, setting boot operation after program memory clear can prevent the
program memory capacity from being exceeded at boot operation.
(c) Parameter-valid drive setting with the DIP switches when using this function
The automatic write to standard ROM setting becomes valid only when the parameter-valid drive are set to the
memory card with the DIP switches.
Therefore, when starting actual operation after the automatic write to standard ROM, deselecting "Auto
Download all Data from Memory card to Standard ROM" in the Boot file tab is unnecessary.
