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.

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 step can be connected to several transitions immediate succeeding by using a:

interpreted parallelism

structural parallelism

sequence selection

AND-convergence

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

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.

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

AND-junction

structural parallelism

sequence selection

AND-convergence

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

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

True

False

The timed variables can be associated to…

steps or transitions

actions or transitions

transitions

steps

How many rules define the GRAFCET evolution?

3 rules

4 rules

2 rules

5 rules

A pit step has only a transition immediate preceding.

True

False
