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.

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

AND-junction

structural parallelism

sequence selection

AND-convergence

A transition-condition…

is always true

can not be time-dependent

can be time-dependent

is always enabled

A predicate is a logical expression with one or more variables.

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.

True

False

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

True

False

Two steps can be directly connected.

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

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

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

GRAFCET abbreviation derives from
