True

False

How many transitions can a pit step have immediate preceding?

None

Two

One

Three or more

The selection of sequence(s) is used when it is desired that the Grafcet evolves:

through one sequence

through one (or more) sequence(s)

through several sequences

through none sequence

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

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

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

True

False

The fundamental elements which constitute Grafcet are:

Transitions, Actions and Transition-Conditions

Steps, Transitions and Actions

Transitions, Steps and Direct Links

is always true

can not be time-dependent

can be time-dependent

is always enabled

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