Sequential function chart (SFC) is a kind of representation form which has been defined in
the international standard IEC 1131-3 as a common element of languages of programmable …

Sequential function chart (SFC) is currently one of the design diagrams for automated
control systems to capture the sequence of operations executed by the system's control …

As opposed to the widely investigated continuous control, this paper concentrates on event-
related control modelling and validation. In this case, the process and related process …

Abstract In designing PLCs (Programmable Logic Controllers) many companies have used
a lot of different languages. In the desire to improve the capability of these PLCs, these …

The transition between the supervisory control theory (SCT) and its implementation in
programmable logic controllers (PLCs) is not straightforward. This is mainly due to the fact …

Programmable Controllers (PCs) are widely applied in the control of manufacturing systems.
The pur pose of this paper is to give some basic concepts for the verification methods of …

This paper proposes a framework for automatic development of control systems from a high
level specification based in Grafcet formalism. Grafcet, or sequential function charts (SFC), is …

In this paper specification of discrete event systems, more specifically flexible production
systems, is performed using two high level specification languages. The first language …

The Petri net (PN) is a well-known bipartite graph theory used to model and analyze discrete
event systems. The properties of PNs can be classified into two types, ie, behavioral …

A comparative synthesis on the formal specification and validation models is presented:
Petri nets, FCCS (functional charts for control systems) and synchronous languages (Lustre …
