Grafchart and Grafcet: A Comparison Between two Graphical Languages Aimed for Sequential Control Applications

Abstract
This paper compares the language Grafcet with the language Grafchart. Both are graphical languages aimed for sequential control applications. Grafcet is aimed for specification of controller structures, i.e., for local level control applications. Grafchart is based on Grafcet, Petri nets and ideas from objectoriented programming and it can be used for any sequential control application, both applications on a local level and on a supervisory level. In addition to this, applications structured with Grafchart can be analyzed with respect to, e.g., deadlock situations, this is thanks to its foundation in Petri nets. In this paper, the similarities and the differences that exit between Grafcet and Grafchart are clarified and discussed.
