(4) Precautions
The following provides the precautions for the automatic write to standard ROM.
(a) When file of the same file name exists in the program memory
When the program memory has a file whose name is the same as that of the file
to be booted from the memory card, that file is overwritten by the file data of the
memory card.
When the program memory does not have a file whose name is the same as that
of the file to be booted from the memory card, the file is added to the program
memory.
If the program memory capacity is exceeded at this time, "FILE ERROR (error
code: 2401)" will occur.
(b) Program memory clear at boot
When files are to be booted from the memory card to the program memory,
whether boot will be executed after program memory clear or without program
memory clear can be selected.
Selecting boot after clearing the program memory clear for the automatic write to
standard ROM prevents the program memory capacity from being exceeded at a
boot.
(c) Parameter-valid drive DIP switch setting for use of this function
The "Automatic all data write from memory card to standard ROM" setting
becomes valid only when the parameter-valid drive DIP switches are set to the
memory card.
Hence, when actual operation is started after completion of the automatic write to
standard ROM, the check mark in the "Automatic all data write from memory card
to standard ROM" check box in the boot file setting need not be removed.
