How-to

Each quiz has 10 multiple-choice questions.

Select the answer that considers correct.

Only after submit the quiz, the responses will be validated.

At the end of the quiz it is reported the result and the test summary.

The timed variables can be associated to…

steps or transitions

actions or transitions

transitions

steps

What enables to perform the steps skip is

the interpretation of the transition-conditions

the step control

the Grafcet situation

none of the previous options

A transition is enabled if one its preceding steps is active.

True

False

The steps skip is a particular case of …

AND-divergence

OR-divergence

AND-convergence

OR-convergence

A step can be connected to several transitions immediate succeeding by using a:

interpreted parallelism

structural parallelism

sequence selection

AND-convergence

When a transition is enabled and the associated condition is true, the transition is not cleared.

True

False

In Gracet when an action D is defined as D:=1, it means that that action stops being executed when the associated step is deactivated.

True

False

A pit transition can have one or more steps immediate preceding.

True

False

A pit step has only a transition immediate preceding.

True

False

Several steps can be directly linked to a immediate succeeding transition through:

AND-junction

structural parallelism

sequence selection

AND-convergence
