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 transition to be enabled has to have all the immediate preceding steps active

True

False

Several steps can be directly linked to a immediate succeeding transition through:

AND-junction

structural parallelism

sequence selection

AND-convergence

How many rules define the GRAFCET evolution?

3 rules

4 rules

2 rules

5 rules

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
