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

How many transitions can a pit step have immediate preceding?

None

Two

One

Three or more

A transition-condition…

is always true

can not be time-dependent

can be time-dependent

is always enabled

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

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

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

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

True

False

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

Macro-steps

Non active steps

Enclosing steps

Active steps

How many rules define the GRAFCET evolution?

3 rules

4 rules

2 rules

5 rules
