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.

In Grafcet which set of steps define the state of the automated system command part?

Macro-steps

Non active steps

Enclosing steps

Active steps

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

True

False

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

The fundamental elements which constitute Grafcet are:

Steps, Transitions and Actions

Transitions, Steps and Direct Links

Transitions, Steps and Transition-Conditions

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 pit step has only a transition immediate preceding.

True

False

A pit transition can have one or more steps immediate preceding.

True

False

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

interpreted parallelism

structural parallelism

sequence selection
