32 Configuring and Using PMCS Wizards PMCS Interface Toolkit
specific MVT small faceplate is selected at runtime, its identity information is passed
to the shared Tabular wizard, wh i ch recognizes which device is bein g s el ected and
displays the data for that individual device. This many-to-one sharing of Tabular
wizards provid e s a tremendous savin gs of system resou rces and dramat ically
increases performance. However, as has been discussed, the Universal Relay and 369
devices are highly flexible and may represent different models of physical devices,
so the Tabular Wizard must be dynamically redrawn based on the nature of the
selected device. This may result in momentary delays in the display of data as the
dynamic redraw occurs.
You can still create individual device wizards independent of the many-to-one
architecture. Creating in dividual device wizards by droppin g a single wizard into a
project without the use of PMCS Power Builder allows you to avoid the dynamic
redraw case for UR and 369 device types, but requires additional system resources.
This tradeoff must be evaluated on a case-by-case basis depending on the nature of
the project bein g developed.
