Operator Workplace Interaction
It has to be decided for each object type if it should have operator graphics in the
Workplace (Process Portal). Examples of object types that should have Operator
Workplace graphics are high level objects such as Motors, Valves, PID-controllers
etc. and objects that are alarm owners.
For objects that will have interaction possibilities in a Workplace, with the user or
other objects, the attribute Aspect Object shall be set on the object type. Aspect
Object is an attribute that decides whether the object will be visible in the Plant
Explorer, or not.
Design
Reuse of graphic elements should be practiced in order to reduce maintenance.
Since the system do not fully support reuse of graphic elements in combination with
Library version handling, a specific method has been developed. The main idea is to
put the reuse elements in a special support library from which they are dragged and
dropped to be instantiated.
The Operator Workplace graphics can be divided in two categories, Faceplates and
Display Elements. These two categories are described below.
Faceplates
Each object with Workplace graphics should have a faceplate named
“MainFaceplate”. The faceplate is used for supervision and control of the object.
The faceplate can have three different views; Reduced, Normal (
Figure 18 ) and
Extended ( Figure 19 ).
The Normal view is mandatory and has a predetermined size to fit into group
displays.
The Reduced view is default view and should contain the minimum of information
that is needed for normal operation. The reduced faceplate can be omitted if the
information will be the same or nearly the same as in Normal view and it is
impossible to reduce the size.
