Transitions, Steps and Transition-Conditions

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

Macro-steps

Non active steps

Enclosing steps

Active steps

Variable Xi represents a Boolean variable such that

if step Xi is active, then Xi=False

if step Xi is active, then Xi=True

if step Xi is deactivated, then Xi=True

if step Xi is deactivated, then Xi=False

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

GRAFCET abbreviation derives from

“GRAphe de Fonctionement Commande Étape-Transition”

“GRAphe Functionnel de Commande Étape-Transition”

“Graphe de AFCET”

“GRAphe de AF Commande Étape-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
