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.

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

Two steps can be directly connected.

True

False

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

A macro-step is a representation of

a set of steps

the Grafcet state

all the logical conditions associated with the transitions

a succeeding steps and transitions

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

Step

Transition

Action

Structure

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 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.

The timed variables can be associated to…

steps or transitions

actions or transitions

transitions

steps

When a transition is enabled and the associated condition is true, the transition is not cleared.

True

False

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.
