Freelance Controlbuider F 2013: Program SFC error - incorrect sequence Selection.
I'm Steel and i'm learning in course ABB training from Ha Noi University of sience and technology.
I'm stuck in a error when i program SFC in Freelance controlbuider F 2013. You can see error: Incorrect sequence selection in image attrack. Can you help me explain what exactly i wrong. Here is link my program:http://www.fshare.vn/file/THMEVWODKG9P.
I look forward to getting your answer.
Thank you for helping.

this is a "problem" we have lived with from the very beginning,
I have a workaround that works perfekt.
Rightclick in the first position under T0, choose Seq.selection convergence add.
This will give you a "t" and an OK configuration.
There is, I think, another way to do this also, but I don´t know how.
Hope it helps.
I´m sorry I was a bit to quick, my answer was not complete.
Your problem is also that it is not allowed to jump backwards in the column were you have the init-step, and its not a need for that.
See my example, the sequence automatically returns to init-step after trans S1-040As.
I hope this example will help you better.
While Tore is right with the priciple, his program has a slightly different logic than yours.
Your program would need to look like attached to work.
The DummyX steps and FINx transitions are necessary because the editor does not allow convergence of a sequence directly after another convergence.
Like Tore wrote, the jump to initial is not necessary (provided your SFC runs in repeat mode), so I skipped it.
Please note the yello marked closure of the selection with the jump.
You might want to check, whether yoy really need all those sequence selections to prevent execution of the next step by moving the flow to the right branches.
If not you can save 2 dummy constructions like here:
