2.2           Project Structure

Within the project, all devices and terminals represented in the circuit diagram need to have a specific structure in the tree.

·            In the equipment structure the top level has to be an object of the type Common Unit. A consistent routing is only feasible within a unit’s structure.

·            Objects of the type Mounting Plate have to be subordinated to the unit. In the model (tree) all devices, terminals and cable ducts that are physically located on the mounting plate, need to be subordinated to the mounting plate. An immediate routing is executed only within a mounting plate. Special transitions have to be defined to enable routing between several mounting plates (see chapter 2.6, Transition between Mounting Plates).

·            In the tree devices and terminals clamped to a mounting rail have to be subordinated to an object of the type Mounting Rail.
