How-to

Each quiz has 10 multiple-choice questions.

Select the answer that considers correct.

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

True

False

Grafcet evolution rule number 5 states that, when a step is simultaneously activated and deactivated it remains active!

True

False

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

True

False

A transition-condition is

all the logical functions associated to each step

always true

all the logical functions associated to each transition

all the logical functions associated to each step and each transition

How many transitions can a pit step have immediate preceding?

None

Two

One

Three or more

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”

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

AND-junction

structural parallelism

sequence selection

AND-convergence

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

True

False

The OR divergence is represented by an horizontal line with one immediate preceding connection and

three connections immediate succeeding

one connection immediate succeeding

two connections immediate succeeding

two or more connections immediate succeeding

A pit step has only a transition immediate preceding.
