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.

How many transitions can a pit step have immediate preceding?

None

Two

One

Three or more

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…

is always true

can not be time-dependent

can be time-dependent

is always enabled

A source transition does not have any immediate preceding step.

True

False

By Grafcet evolution rule number 4 several transitions which can be simultaneously cleared…

are cleared sequentially

are cleared simultaneously

just one is cleared

are not cleared

Two steps can be directly connected.

True

False

How many rules define the GRAFCET evolution?

3 rules

4 rules

2 rules

5 rules

Situation, is the Grafcet term used to designate a set of

transitions active in a given instant

steps non active in a given instant

steps active in a given instant

transition-conditions active in a given instant

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

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
