2 PROGRAM CONFIGURATION
Using the engineering tool, multiple programs and POUs (Program Organization Units) can be created.
Thus, programs and POUs can be sorted by processing.
This chapter describes the program configuration.
For the POU, refer to the following.
Page 11 PROGRAM ORGANIZATION UNIT (POU)
Project
A project is a collection of data (including programs and parameters) to be executed by the CPU module.
Only one project can be written to one CPU module.
For one project, one or more program files need to be created.
Program file
A program file is a collection of programs and POUs.
One program file consists of one or more program blocks.
The operation on the program file level can be changed, such as, the execution type of a program can be switched from scan
execution type to standby type, or whether to write data to the CPU module.
