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

The steps skip is a particular case of …

AND-divergence

OR-divergence

AND-convergence

OR-convergence

A source transition does not have any immediate preceding step.

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

A predicate is a logical expression with one or more variables.

True

False

The OR divergence is represented by an horizontal line with one immediate preceding connection and

three connections immediate succeeding

one connection immediate succeeding

two connections immediate succeeding

two or more connections immediate succeeding

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

True

False

Variable Xi represents a Boolean variable such that

if step Xi is active, then Xi=False
