2. A number of computers linked together with a central processing point
known as a Server which is accessible to all computers. Networks
affect CX-Supervisor in that further Network associated options are
available if the computer is Network connected.
Non-Volatile A point that is designated as ‘non-volatile’ is a point whose value is saved
on disk and automatically reloaded when CX-Supervisor resumes
execution.
NOT A logic operator used to interrogate Boolean type points which produces
the Boolean inverse of the supplied argument. An example of NOT is that
if a is a statement and is ‘FALSE’, then NOT returns ‘TRUE’. If a is a
statement and is ‘TRUE’, then NOT returns ‘FALSE’.
Object In CX-Supervisor, an object can be text, graphics, a control, a bitmap, or
ActiveX 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 pushbutton, a toggle
button, a slider, a trend graph, a rotational gauge or a linear gauge.
OLE-DB OLE-DB is the underlying database technology, on which ADO relies.
OLE-BD is designed to be the successor to ODBC.
Operand The term used for constants or point variables.
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.
OR A logic operator used to interrogate Boolean type points. OR returns
‘TRUE’ if any of the supplied arguments are ‘TRUE’. An example of OR
is that if a is a statement and b is a statement, OR will return ‘TRUE’ if
either a and b are ‘TRUE’. If both statements return ‘FALSE’ then OR
will return ‘FALSE’.
Pages The combination and manipulation of pages containing objects within
projects forms the basis of CX-Supervisor. More than one page can exist
for each project. The pages in a project provide the visual aspect of CX-
Supervisor corresponding to a display with the objects contained in each
page providing a graphical representation of the system being monitored.
Parameter Association A Parameter Association enables values, either constant 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 the computer’s Visual Display Unit
(VDU) is defined by the number of pixels across and the number of pixels
down (e.g. 1024 x 768).
