Program Files
Program files contain controller information, the main control program, and any
subroutine programs. The first three program files are required for each processor
file. These are:
•
File 0 - System Program
This file stores the controller configuration and other system information.
•
File 1
This file is reserved for internal controller use.
•
File 2 - Main Ladder Program
This file stores the main control program.
•
Files 3 Ć 255 - Subroutine Ladder Program
These files are optional and used for subroutine programs.
Most of your work with program files will be in file 2, the main program file. This
file contains your ladder logic program which you create to control your application.
