Sequence rules
- A transition is considered released once all the immediately preceding steps are active. A transition is triggered once it has been released and its condition has the value “1”. A transition with the value “1” is shown in green in FluidSIM, regardless of whether the step linked to it is active or inactive.
- The relevant transition is triggered at the same time and does not take any time.
- Since triggering a transition does not take any time, a step can be activated and deactivated at the same time (even across various intermediate steps). An active step remains active in this situation. A loop of steps is only run through once at one point in time (see example: Grafcet/Grafcet06.ct).
