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.

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 pit transition can have one or more steps immediate preceding.

True

False

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 Grafcet initial situation is characterized by steps

Active at the final time

Deactivate at the initial time

Active at the initial time

Deactivate at the final time

Several steps can be directly linked to a immediate succeeding transition through:

AND-junction

structural parallelism

sequence selection

AND-convergence

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…

is always true

can not be time-dependent

can be time-dependent

is always enabled

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

Macro-steps

Non active steps

Enclosing steps

Active steps

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
