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.

True

False

What enables to perform the steps skip is

the interpretation of the transition-conditions

the step control

the Grafcet situation

none of the previous options

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

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

interpreted parallelism

structural parallelism

sequence selection

AND-convergence

Variable Xi represents a Boolean variable such that

if step Xi is active, then Xi=False

if step Xi is active, then Xi=True

if step Xi is deactivated, then Xi=True

if step Xi is deactivated, then Xi=False
