Trend Plot 126
---------------------------------------------------------------
The changes to an active trend plot described below are
displayed immediately. However, trend set definitions in
the DCS cannot be overwritten in this way.
In order to be able to a use changed or newly defined
trend set in "UNIGYR-VISONIK Insight" at a later date, you
must file this locally.
For network systems, all displayed points of a Trend Set
must belong to the same DCS.
Address: Entry of a valid technical address or user address.
Parameter: Entry of the parameters to be displayed. In the absence of
an entry, "Insight" automatically displays the main value.
Graphic depiction: Point: Depiction of each value by a point.
Step: Interpolation by means of a stepped curve.
Line: Interpolation by means of connecting lines.
For points with discrete values (e.g. ST, SC) the stepped
form must always be chosen.
The acquisition and depiction of values:
The DCS automatically supplies the Event values of the
points to be depicted.
In the meantime, the trend plot function continues to plot
the curves about every 10 seconds horizontally. As soon
as actual values are available, it makes the appropriate
corrections.
Buffer size The time taken to save and display the acquired values.
For Trend Sets which were loaded from the DCS, the
default for this value is always one hour.
