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 always true

can not be time-dependent

can be time-dependent

is always enabled

A step can be connected to several transitions immediate succeeding by using a:

interpreted parallelism

structural parallelism

sequence selection

AND-convergence

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

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

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

Macro-steps

Non active steps

Enclosing steps

Active steps

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.

True

False

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

AND-junction

structural parallelism

sequence selection

AND-convergence

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

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

Two steps can be directly connected.

True

False
