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-condition is

all the logical functions associated to each step

always true

all the logical functions associated to each transition

all the logical functions associated to each step and each transition

Two steps can be directly connected.

True

False

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

A transition is enabled if one its preceding steps is active.

True

False

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.

A transition-condition (receptivity) is every logical function associated to each

Step

Transition

Action

Structure

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

are cleared sequentially

are cleared simultaneously

just one is cleared

are not cleared

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

True

False
