3.3 Settings for Creation and Execution of Multiple Sequence
Programs
When multiple sequence programs are created, the execution type can be specified for
each program, e.g. a program started only once at startup or a program executed at fixed
intervals.Note16
(1) Applications for multiple sequence programs creation
A program can be divided into multiple programs on the basis of each control unit and
stored into the CPU module. (They can also be stored as a single program.)
This enables programming to be shared by each designer for each processing unit.
* 1 : Refer to the following sections for the program storage location.
•Basic model QCPU : Section 5.1.1
•High Performance model QCPU, Process CPU, Redundant CPU,
or Universal model QCPU : Section 5.2.1
(2) Settings required for execution of multiple programs
When multiple programs are to be executed by the CPU module, the file names
(program names) and execution conditions of the programs must be preset.
Make the program settings in the PLC parameter dialog box of GX Developer.
( Section 3.3.6)

Note3.17
Since the Basic model QCPU cannot execute multiple programs, the settings for creation and
execution of multiple sequence programs are not available.
