(b) File-divided structuring
Programs are stored in file format.*1
Changing the file name allows the CPU module to store multiple programs.
Note4
* 1 : The program storage destination changes depending on the CPU module.
(i
Hence, a program can be created separately by multiple designers, or can be
divided and managed/maintained individually according to the processes and
functions.
If specifications are changed, it is necessary to correct/debug only the
corresponding program.
1) When program is created separately by multiple designers
* 2 : The execution order and execution conditions of the program can be set by program setting

Note1.5
Since the Basic model QCPU cannot store multiple programs by changing the file name, it
cannot execute file-divided structuring.

Multiple program writing is enabled
by using different file names.
