11.4.11 Marker
A marker in the Picture window is also used to display an
updated analog value (measured value, positioning com-
mand, etc.)
Here, any type of mark (short dash, arrow, triangle) runs
along a (possibly invisible) straight line.
Markers must always be connected to an updating chan-
nel of the "bar" type (COS, ACT dialogue).
Drawing a marker:
- Draw a straight line. The beginning of the line defines
the starting value.
- Draw the mark at the desired position anywhere, or on
the straight line.
- Mark the marker and straight line.
- Combine the two figures.
Important:
If the mark and the straight line intersect, the mark must
always lie in front of the straight line. (See the operations
"Allocation to Foreground/Background")
For combined marker elements, the element used first
may not be a straight line. You can draw a triangle, for
example, with the "Polyline" function. For a half circle,
begin with an arc.
11.4.12 Button
Produces a square grey button which, when connected to
an updating channel, can be used, for example, to select a
support picture or to start a COLBAS task.
The colour of the button is not influenced by the definition
in the COS, ACT dialogue. It always remains grey, even in
the Picture window.
