Steps
Steps are either active or inactive and can be linked by actions. The actions of active steps are executed. The sequence of a GRAFCET is described by the transitions from a previous to a subsequent step. Steps and transitions have to alternate in the plan.
The creation and simulation of GRAFCETs in FluidSIM is illustrated in the following using simple examples.
Drag a step into
a newly created circuit diagram.
Each step has to be assigned a name. If a step is to be active at the start of the sequence control, it is marked as the initial step.
Open the step's
dialogue box by double-clicking on it or via the menu
(Edit- Properties...),
enter “1” as the name and select the type “initial
step”.
Start simulation
with 
or via the menu
(Execute- Start).
Active steps are marked with a point. Additionally, active steps are framed in green.
