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

A transition-condition…

is always true

can not be time-dependent

can be time-dependent

is always enabled

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 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

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 execution time of a continuous action

is equal to the activation time of the associated step.

is equal to the deactivation time of the associated step.

is larger than the activation time of the associated step.

is less than the time of activation of the associated step.

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

The timed variables can be associated to…

steps or transitions

actions or transitions

transitions

steps
