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.

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 transition-condition…

is always true

can not be time-dependent

can be time-dependent

is always enabled

The execution time of a continuous action

is equal to the activation time of the associated step.

is equal to the deactivation time of the associated step.

is larger than the activation time of the associated step.

is less than the time of activation of the associated step.

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

The fundamental elements which constitute Grafcet are:

Transitions, Actions and Transition-Conditions

Steps, Transitions and Actions

Transitions, Steps and Direct Links

Transitions, Steps and Transition-Conditions

A pit step has only a transition immediate preceding.

True

False

A source transition does not have any immediate preceding step.

True

False

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

True

False

The steps skip is a particular case of …

AND-divergence

OR-divergence

AND-convergence

OR-convergence
