After working through this module, the students have additional knowledge regarding the
design of the user interface of an operator station. They are able to make additional
information available on the detail level. To this end, they use adapted message lists and
trend curves. The students are able to combine created composites into a user defined
object and redesign existing objects as user defined objects. These objects can then be
made available for reuse.

In this chapter, some aspects of OS engineering are considered in greater depth. While in
chapter P02-01 automatic generation of process images was primarily discussed, now
supplementary techniques for designing process control are described.

The flow diagrams (refer to P02-01) are usually arranged in the following hierarchical
levels:
levels:
– Plant display
– Area display
– Plant section/group display
– Detail display
This classification can result from the plant hierarchy. While the upper levels aim for a good
overview of the entire plant or corresponding areas, the plant section display and the detail
display are to provide considerably more information about the area under consideration to
make situation-conforming settings of parameters or fault diagnosis possible.

In addition to detailed information about the current state of the areas under consideration,
the representation of process values in curves is particularly helpful to analyzing
deviations. In curves, the time characteristics of a process value are represented. With one
glance, the operator can immediately read off the following information:
the representation of process values in curves is particularly helpful to analyzing
deviations. In curves, the time characteristics of a process value are represented. With one
glance, the operator can immediately read off the following information:
– The time when striking changes occurred in the course
– Process values at the time mentioned above
– Gradients for certain points in time
– Dependencies between process values at simultaneous display
– Extreme values (when and how large)
– Fluctuation range
– Set point deviations
– Frequencies
Curve displays provide the operator with an expanded basis for decisions regarding control
action. If a process value is outside the permissible range, based on the curve the user is
informed of process value development in the most recent past and can detect whether the
value continues to change for the worse or is improving.
