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

Two steps can be directly connected.

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”

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

AND-junction

structural parallelism

sequence selection

AND-convergence

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

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

By Grafcet evolution rule number 4 several transitions which can be simultaneously cleared…

are cleared sequentially

are cleared simultaneously

just one is cleared

are not cleared

How many transitions can a pit step have immediate preceding?

None

Two

One

Three or more

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

True

False
