vidéo : Cours Grafcet | Définition et principe

Grafcet is a graphical programming language used in industrial automation. It is a sequential function chart that describes the steps of a process in a graphical way. Grafcet is used to program PLCs (programmable logic controllers). Grafcet is defined by a set of rules that govern its construction. The basic elements of Grafcet are: * States: These represent the different states of the process. * Transitions: These represent the events that cause the process to move from one state to another. * Actions: These represent the tasks that are performed in each state. The principle of operation of Grafcet is that the process starts in the initial state and then transitions to other states based on the occurrence of events. The actions that are performed in each state are executed when the process is in that state. Grafcet has a number of advantages over other programming languages. It is easy to understand and use, and it is well suited for describing complex processes. Grafcet is also very efficient, and it can be used to program PLCs quickly and easily.
