LEARN, PROGRAM AND TEST SEQUENTIAL FUNCTION CHARTS IN AN INTERACTIVE E-LEARNING COURSE

Sequential function charts (SFC) according to IEC61131-3 are often not very popular in industrial automation. This is mainly due to the fact that it was not learned systematically or its capabilities were never experienced. The high-level interactive e-learning tool described in this contribution offers a didactically well structured step by step e-learning course, disclosing all the necessary details. A graphical SFC-editor allows the user to freely program his own SFC. The user is only restricted to predefined actions and transitions, but with the benefit that he or she can test acquired SFC with real-life plant simulations. Analysis of SFC based on Petri-Net theory and recipe control of batch plants complete the course.
