1.2 Program Storage and Operation

OVERVIEW
(b) File-divided structuring
Note1.4
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 CHAPTER 5)
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
( Section 3.3.6(1)).

Note1.4
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.
