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 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

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

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

A macro-step is a representation of

a set of steps

the Grafcet state

all the logical conditions associated with the transitions

a succeeding steps and transitions

Two steps can be directly connected.

True

False

A source transition does not have any immediate preceding step.

True

False

How many rules define the GRAFCET evolution?

3 rules

4 rules

2 rules

5 rules

The timed variables can be associated to…

steps or transitions

actions or transitions

transitions

steps

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

True

False
