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.

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

AND-junction

structural parallelism

sequence selection

AND-convergence

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

True

False

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

How many transitions can a pit step have immediate preceding?

None

Two

One

Three or more

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

Step

Transition

Action

Structure

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

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

interpreted parallelism

structural parallelism

sequence selection

AND-convergence

The selection of sequence(s) is used when it is desired that the Grafcet evolves:

through one sequence

through one (or more) sequence(s)

through several sequences

through none sequence

A source transition does not have any immediate preceding step.

True

False

A transition-condition…

is always true

can not be time-dependent

can be time-dependent

is always enabled
