“…A first step toward that goal is to define a meta-model. An overview of the existing meta-modeling approaches of GRAFCET is presented by Julius et al [1]. Furthermore, they propose a meta-model suitable for model-driven development in PLC programming.…”

“…However, the formalization of terms, i.e. logical and arithmetic expressions in conditions and assignments, has not been considered in [1]. They are only represented as strings in the target language syntax, which hinders formal verification.…”

“…A N important part of the engineering process of cyberphysical systems is the specification of the control code. Formal methods can avoid the error-prone human interpretation of informal specifications and increase the quality of control code by automatic code generation [1]. However, formal control design has not gained much acceptance in practice.…”

“…There, the first subject is to completely define the abstract syntax of the used specification language GRAFCET in Section IV-A. This is done by building on the work of Julius et al [1], via a meta-model (Fig. 1: GRAFCET meta-model) including the terms in conditions (e.g.…”

The graphical modeling language GRAFCET is used as a formal specification language in industrial control design. To use these formal specifications for model-driven development of control code it is beneficial to ensure their syntactical and semantic correctness. Therefore in this paper, a detailed metamodel for GRAFCET is presented, which takes so-called terms into account, i.e. logical and arithmetic expressions in conditions and assignments. The meta-model and additionally proposed invariants allow to create syntactically correct GRAFCET instances. Based on this, a translation of GRAFCET to Guarded Action Language (GAL) is presented. The resulting transition system in GAL forms the basis for a semantic analysis of the GRAFCET instances by means of model checking in future research. Finally, the models are then employed for automatic code generation in Structured Text.

The dependability characteristic of the control software of manufacturing systems is highlighted more than before, going through repeated changes to cope with various and varying requirements. Formal methods are researched to be applied to automation system engineering to obtain a more effective and efficient quality assurance. One of the approaches, a formal specification language named Generalised Test Tables has been developed with the aim of intuitiveness and accessibility for automation application developers. The result of the experiments conducted to assess the usability of this language is presented here. Focussing on evaluating effectiveness and user satisfaction, three paper-based experiments have been conducted with students at the bachelor and master level. The evaluation results point to positive usability in both comparative effectiveness to conventional language, that is, Petri Nets, and subjective perception of user satisfaction.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
