Structures

The Aspect Object
different structures, depending on which context is to be viewed.
Structures are the graphical representations of the relations that exist between
different aspect objects. Since there are usually a number of different types of
relations between objects, an aspect object can be part of more than one structure.
The difference between the structures of Plant Explorer and Windows Explorer, is
that in Plant Explorer there are a number of structures representing the same plant.
Structures can be built and improved at any time. Examples of the most common
structures are Object Type Structure, Control Structure and Functional Structure.

The Operator Workplace and Plant Explorer Workplace

The Operator Workplace
The Operator Workplace is the environment from which the operator views and
controls the process in the plant. By logging in as an Operator, the Operator
Workplace will be started.
After logging in, the start screen is displayed.
It is usually configured by the Application Engineer and intended as a starting point
for an Operator controlling the plant.
In Compact HMI 800 a number of different types of displays are available.
The most important are process displays for supervision, faceplates to control real
process objects, trend displays and alarm displays to monitor process anomalies.
These displays are presented in the Display Area (see
appear as base displays or overlap displays. Base displays cover the entire display
area while one or more overlap displays normally cover a smaller portion of the
display area (and the base display).
