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.

A transition to be enabled has to have all the immediate preceding steps active

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

How many rules define the GRAFCET evolution?

3 rules

4 rules

2 rules

5 rules

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

True

False

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

Two steps can be directly connected.

True

False

A source transition does not have any immediate preceding step.

True

False

The fundamental elements which constitute Grafcet are:

Transitions, Actions and Transition-Conditions

Steps, Transitions and Actions

Transitions, Steps and Direct Links

Transitions, Steps and Transition-Conditions

Variable Xi represents a Boolean variable such that

if step Xi is active, then Xi=False

if step Xi is active, then Xi=True

if step Xi is deactivated, then Xi=True

if step Xi is deactivated, then Xi=False

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
