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

interpreted parallelism

structural parallelism

sequence selection

AND-convergence

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 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 source transition does not have any immediate preceding step.

True

False

A transition-condition…

is always true

can not be time-dependent

can be time-dependent

is always enabled

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

Two steps can be directly connected.

True

False

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

True

False

A pit step has only a transition immediate preceding.

True

False

The fundamental elements which constitute Grafcet are:

Transitions, Actions and Transition-Conditions

Steps, Transitions and Actions

Transitions, Steps and Direct Links
