In Codesys make a traffic light SFC sequencer that gives $30$seconds of Green followed by $10$ seconds of Amber then $20$seconds of red.

Use Boolean variables Green, Amber, Red for the steps.

Hints:

$$ The Structured text code $$S$1.$T $>$ T#$40$s$$ will go true when the Step$1$ time exceeds $40$seconds;

$$ The T# tells Codesys it$$s a time.

$$ Don$$t forget the Jump back to the beginning!

The problm is that the Function Block Test page on Codesys have no space to put the code except Variations. Please help
