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

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

A macro-step is a representation of

a set of steps

the Grafcet state

all the logical conditions associated with the transitions

a succeeding steps and transitions

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

True

False

A transition-condition (receptivity) is every logical function associated to each

Step

Transition

Action

Structure

Two steps can be directly connected.

True

False

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.

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

Situation, is the Grafcet term used to designate a set of

transitions active in a given instant

steps non active in a given instant

steps active in a given instant

transition-conditions active in a given instant

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”
