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 timed variables can be associated to…

steps or transitions

actions or transitions

transitions

steps

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

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

True

False

How many rules define the GRAFCET evolution?

3 rules

4 rules

2 rules

5 rules

Two steps can be directly connected.

True

False

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

A transition-condition…

is always true

can not be time-dependent

can be time-dependent

is always enabled

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

AND-junction

structural parallelism

sequence selection

AND-convergence

A transition is enabled if one its preceding steps is active.

True

False

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

True

False
