7.3 PARAMETER DEFINITIONS
The following parameters are associated with the components listed in table 7.2.2 , above. The list is divided
into basic and advanced.
7.3.1 Basic parameters
Notes:
1 Not all components have all the following parameters associated with them. The component de
fi ni-
tions in section 7.4 de fi ne each component’s parameters.
2 The generic term ‘solid objects’ as used in this description includes rectangles, lines, arcs, rounded
rectangles, ovals, polygons and polylines. Lines and arcs do not have a background colour as they
cannot be fi lled.
3. Default parameter units are in ‘percentage of screen width/height’. The picklist next to each dimen-
sion fi eld allows pixels to be used instead.
Table 7.3.1 Basic level parameters (sheet 1 of 2)
Arc Angle For Arcs only, the number of degrees of arc drawn anti-clockwise (counter-clockwise) from the
Start Angle. Negative angles draw clockwise. See fi gure 7.4.20a for de fi nitions.
Arc Height For Rounded Rectangles only, this is double the vertical distance from the corner of the (un-
rounded) rectangle at which the curve is to start. To draw ‘circular’ corners, this value must be
3/2 times the Arc Width. The Arc height value must be less than half the Rectangle height. Per-
cent units are relative to the rectangle height, not the screen height.
Arc Width For Rounded Rectangles only, this is double the horizontal distance from the corner of the (un-
rounded) rectangle at which the curve is to start. To draw ‘circular’ corners, this value must be
2/3 the Arc Height. The Arc width value must be less than half the Rectangle width. Percent units
are relative to the rectangle width, not the screen width.
Background colour The fi ll colour of solid objects; the background colour for the main page, trend charts, text mes-
sages etc. For Bargraphs, the colour ‘behind’ the bar.
Button Text For operator buttons, Dialogue Action and Navigation Action. Allows button text to be entered.
Event button text is de fi ned in Event Button Con fi guration, described in s ection 4.3.7 .
Channel Allows a channel to be selected for bargraph, numeric, value etc. display.
Draw edge If set to ‘Yes’, this causes the outline shape of a solid object to be drawn in the foreground colour.
If set to ‘No’, the object’s outline is not drawn.
Draw Order Allows a layer scheme to be introduced. Items with higher draw order values are overlaid on
components with lower draw order values. The Draw Order feature is included speci fi cally to al-
low a dynamic element (such as a bargraph) to be placed ‘on top of’ a background, static image.
A dynamic element is always drawn on top all other elements at update time. When one or more
dynamic elements are placed on top of one another, the results are unpredictable.
Edit Parameter For operator buttons, allows the user to select the parameter type (e.g Channel N Alarm 1) to be
edited when the button is operated. The parameter number (N) is entered in the ‘N value’ fi eld.
Event Button For Event buttons, this allows the user to assign an Event button to the User Screen Button to be
displayed.
Feature For ‘Channel data’ only, allows the type of data to be displayed (e.g. Current value), to be selected
from a pick-list.
Fill Area If set to ‘Yes’, this causes a solid object to be fi lled with the background colour. If set to ‘No’, the
inside of the object is transparent. If ‘draw edge’ is also set to ‘No’, the object is invisible.
Foreground Colour The line colour of solid objects. The bar colour of bargraphs (default = normal point colour). The
colour of Text and of numeric values. Where applicable, this overrides channel colour.
