The plant is represented by five electronic Libra cylinders, one Stylos and one light.
The
Libra
cylinders represent the doors inside the building and they are identified by the depart-
ment name to which they give access. The main building entrance (NORTH MAIN DOOR), is repre-
sented by an online
Stylos
credential reader and the light, installed into the main entrance door.
The light goes ON when access is granted, to indicate the door opening, that in a real context
can be done by means of an electric lock or electric strike.
