They turn to 1 when a wagon is present at the given point. It is not always possible to know the home state and the bound. Remember me Forgot password? A stable situation has been reached 1.

I too believe it is rather easy to duplicate SFC using Ladder logic.

Look at the first figure in chapter 3. Decotignie, Reduction R3: I hope this info helps you in your search. Decotignie, Reduction Geafcet It is assumed that each computer may be in one of the following states: Is it a state graph?

Page 26 to 28 give you the translation of a simple grafcet or SFC. Is it without loop?

You can manually translate an SFC to ladder logic, which isn’t all that difficult. Is it without conflict? The transition defined on the top part of the ladder logic program will then establish the switching from on step to the next. Unfortunately, the translating is done a little hasty.

Set to 1 all the actions that belong to A1 4. It is frafcet always possible to find the home state and the bound. If, after clearing, the state is unchanged goto 6 4.

Decotignie, Reduction R1: I didn’t find this info on the AB website either. In the ladder diagram you have to change E1 and E2 to X1 and X2 respectively, and then it’s correct. As long as you have the possibility to grafect a memory, beit monostable or bistable, and have boolean logic available, then it’s possible to use SFC as a design method.
