Parameter A Parameter Association enables values, either constant
Association or stored in a point, to be passed to a Server Query.
Pixel A single displayable point on the screen from which a
displayed image is constructed. The screen resolution of

Point variable A point within the CX-Supervisor script language that
stores a value or string assigned to that point.
Point A point is used to hold a value of a predefined type -
Boolean, Integer, Text, etc. The contents of a point may
be controlled by an object or I/O mechanism such as
PLC communication. The contents of a point may
control the action or appearance of an object, or be used
for output via an I/O mechanism.
See also Boolean type, Integer type, point variable, Real
type and Text type.
Project A CX-Supervisor application will consist of one or a
number of pages linked together. The pages may
contain passive or active graphics, text or animations,
and may be grouped together logically to form a project.
A project may consist of many pages, or simply a single
page. Projects may be built and tested within the CX-
Supervisor development environment, and run stand-
alone under the CX-Supervisor run-time environment.
Only one project at a time may be open for editing within
the CX-Supervisor development environment.
Real type A type of point where the value of the point can be any
number, including those containing a decimal point.
Recipe A recipe is a set of pre-defined steps used to perform a
particular task. A CX-Supervisor project may contain
zero or more number of recipes. Recipes are defined in
the development environment and executed, or
downloaded, in the run-time environment.
Run-Time SCADA applications are run using the run-time
Environment environment of CX-Supervisor, following creation of the
application in the CX-Supervisor development
environment.
SCADA Supervisory Control and Data Acquisition.
Server A Server is the central processing point of a Network that
is accessible to all computers. Networks affect CX-
Supervisor in that further associated options are
available if the computer Network is connected.
Server Application An application that can be used to view or interact with,
whilst currently within CX-Supervisor.
