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.

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

True

False

A pit step has only a transition immediate preceding.

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

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 source transition does not have any immediate preceding step.

True

False

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

Step

Transition

Action

Structure

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

interpreted parallelism

structural parallelism

sequence selection

AND-convergence

Two steps can be directly connected.

True

False

How many transitions can a pit step have immediate preceding?

None

Two

One

Three or more

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
