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 steps skip is a particular case of …

AND-divergence

OR-divergence

AND-convergence

OR-convergence

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

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”

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

Two steps can be directly connected.

True

False

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

AND-junction

structural parallelism

sequence selection

AND-convergence

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 transition-condition…

is always true

can not be time-dependent

can be time-dependent

is always enabled

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

True

False

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

True

False
