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.

How many rules define the GRAFCET evolution?

3 rules

4 rules

2 rules

5 rules

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

AND-junction

structural parallelism

sequence selection

AND-convergence

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

How many transitions can a pit step have immediate preceding?

None

Two

One

Three or more

The timed variables can be associated to…

steps or transitions

actions or transitions

transitions

steps

The selection of sequence(s) is used when it is desired that the Grafcet evolves:

through one sequence

through one (or more) sequence(s)

through several sequences

through none sequence

The execution time of a continuous action

is equal to the activation time of the associated step.

is equal to the deactivation time of the associated step.

is larger than the activation time of the associated step.

is less than the time of activation of the associated step.

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

True

False

A pit step has only a transition immediate preceding.

True

False

GRAFCET abbreviation derives from

“GRAphe de Fonctionement Commande Étape-Transition”

“GRAphe Functionnel de Commande Étape-Transition”

“Graphe de AFCET”

“GRAphe de AF Commande Étape-Transition”
