Abstract :
Some implementation aspects of the Grafcet macro-action concept are presented. Firstly, two different interpretation algorithms are discussed, each of them observing the evolution rules specified by the Grafcet standard, but leading to different results. After that, an algorithm developed to validate the coherence of the macro-actions of the global Grafcet is presented. Finally, some details regarding code generation of the Grafcet evolution system are discussed
