SECTION 3
Points
This chapter describes CX-Supervisor points and the procedures associated
with the creation, amendment and removal of points using the Points Editing
facility. The application of external sources to points is also described.
3-1 What is a Point?
A point is a variable used internally by CX-Supervisor. All points within CX-
Supervisor have a name, group and type associated with them.
CX-Supervisor provides a set of pre-defined System ($) Points, which are
detailed in chapter 3 Points.
3-2 About the Point Editor
The Point Editor allows the viewing, creating, modifying and removing of
points from the points database.
To open the Point Editor dialog box, click the button.
An example of the Point Editor dialog box is as follows:
The typeface of the editor can be amended by selecting Preferences from the
File menu. This is especially useful when printing.
3-3 Viewing Points in the Point Editor
The Point Editor view of the points database can be tailored by filtering or
sorting the available points.
Note: System Points cannot be modified.
Note: To select a range of points, click on a point to mark the start of the range and
click again with the <Shift> key down to mark the end.
Note: To individually select more than one point, click while holding the <Ctrl> key
down.
Note: The short-cut keyboard combinations for Cut, Copy and Paste operations are
valid within the Point Editor. Highlight one or more points and type <Ctrl>+X to
cut or <Ctrl>+C to copy; use <Ctrl>+V to paste. Since the cut and copy
operations store the information in the Windows Clipboard, points may be
pasted to another CX-Supervisor application. See also Chapter 3 Quick
creation of many points.
Note: If the I/O type ends with ' ' and a number, it is an array point with the shown
number of elements.
