I/O type Input / Output type. An attribute of a point that
defines the origin and destination of the data for
that point. The data for a point can originate (be
input from) and is destined (is output to) to the
internal computer memory, PLC, DDE target
application.
Icon Pictorial representations of computer resources
and functions. The CX-Supervisor development
environment and run-time environment are run
from icons. Icons are also used in CX-Supervisor
to indicate an OLE object.
Microsoft Excel A spread sheet application.
Microsoft Windows A windowing environment for personal computers,
that is noted for its GUI, and for features such as
multiple typefaces, desk accessories (such as a
clock, calculator, calendar and notepad), and the
capability of moving text and graphics from one
application to another via a clipboard.
CX-Supervisor will run only under Microsoft
Windows.
Microsoft Word A word processing application.
See also SVGA mode and VGA mode.
Object In CX-Supervisor, an object can be text, graphics,
a control, a bitmap, or OLE object as created in the
development environment. A complex object can
exist as a combination of two or more objects of
any of the above types. Specifically, graphical
objects can be categorised as a line, an arc, a
polygon (including a square and rectangle), a
round rectangle, an ellipse (including a circle), or a
Polyline. A control is essentially a complex
graphic object and is specifically either a button, a
toggle button, a slider, a trend graph, a rotational
gauge or a linear gauge.
OLE Object Linking and Embedding. Used to transfer
and share information between Microsoft Windows
based applications and accessories. When OLE
is used in CX-Supervisor, it is possible to view or
even edit a file from a target application.
OLE-DB OLE-DB is the underlying database technology, on
which ADO relies. OLE-BD is designed to be the
successor to ODBC.
Operator A symbol used as a function, with infix syntax if it
has two arguments (e.g. "+") or prefix syntax if it
has only one argument (e.g. NOT). The CX-
Supervisor script language uses operators for
built-in functions such as arithmetic and logic.
