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

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-condition (receptivity) is every logical function associated to each

Step

Transition

Action

Structure

A pit transition can have one or more steps 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

Transitions, Steps and Transition-Conditions

How many rules define the GRAFCET evolution?

3 rules

4 rules

2 rules

5 rules

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.

Grafcet evolution rule number 5 states that, when a step is simultaneously activated and deactivated it remains active!

True

False

In Gracet when an action D is defined as D:=1, it means that that action stops being executed when the associated step is deactivated.

True

False

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
