Compulsory commands
Compulsory commands can be used to control partial GRAFCETs regardless of their normal sequence. There is an entry mask to help you enter these commands in FluidSIM. There are four types of compulsory command. They are shown here using four examples (see example: Grafcet/Grafcet16.ct).
- G12 {8, 9, 11}Setting a specific situation. This example activates steps 8, 9 and 11 of partial GRAFCET 12.
- G12
{*}
Freezing a partial GRAFCET. In this example, the current situation for partial GRAFCET 12 is maintained as it is. No further transitions are triggered. - G12
{}
Setting a blank situation. All steps in partial GRAFCET 12 are deactivated in this example. - G12
{INIT}
Setting the initial situation. In this example, the steps in partial GRAFCET 12 that are marked as initial steps are activated.
