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.

A Grafcet initial situation is characterized by steps

Active at the final time

Deactivate at the initial time

Active at the initial time

Deactivate at the final time

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

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

interpreted parallelism

structural parallelism

sequence selection

AND-convergence

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

By Grafcet evolution rule number 4 several transitions which can be simultaneously cleared…

are cleared sequentially

are cleared simultaneously

just one is cleared

are not cleared

Two steps can be directly connected.

True

False

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

True

False

The timed variables can be associated to…

steps or transitions

actions or transitions

transitions

steps
