PLC programming conventions
Program organization
During the PLC programming, you must structure your program into finished program parts (subroutines). The programming
language for the S7-200 offers you the capability to set up your user program in a structured manner.
There are the following two types of programs:
● Main program
● Subroutine
Eight levels of programming are possible.
