2.3  Settings When Program is Divided
When one sequence program is divided into multiple programs, execution conditions, such as executing a 
program only once at start-up or executing a program at fixed intervals, can be set for each program.
(1) Control by multiple programs dividing one program
The CPU module can store multiple programs divided on the basis of each control unit.
This enables programming of one sequence program by two or more designers.
(2)
Settings required for execution of multiple programs
To execute multiple programs in the CPU module, names (file names) and execution conditions of the 
programs must be set.
Set them in the Program tab of the PLC parameter dialog box.
