Method for generating a control program for an automation system and programming tool

Abstract

The application relates to a method for generating a control program for controlling an automation system, the method comprising: generating a graphical diagram of the control program according to the graphical programming language ladder diagram LD for Programmable Logic Controllers in a diagram generating step; generating a data flow graph as a representation of the graphical diagram in a graph generating step, wherein elements of the graphical diagram are represented as nodes and connecting lines between elements of the graphical diagram are represented as edges of the data flow graph; and generating a version of the control program executable by a programmable logic controller based on the data flow graph in a program generating step. The application further relates to a programming tool for carrying out the method.
