What are the elements of SFC?
Main components of SFC are:
- Steps with associated actions;
- Transitions with associated logic conditions;
- Directed links between steps and transitions.
What is transition in SFC?
A transition must include the condition for the subsequent step to be active as soon as the value of the condition yields TRUE . Therefore, a transition condition must yield TRUE or FALSE .
What is grafcet used for?
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 object-oriented programming and it can be used for any sequential control application, both applications on a local level and on a supervisory level.
How does ladder logic work?
Ladder logic has contacts that make or break circuits to control coils. Each coil or contact corresponds to the status of a single bit in the programmable controller’s memory. Each rung of ladder language typically has one coil at the far right. Some manufacturers may allow more than one output coil on a rung.
