Appendix G Glossary of Terms
327
Nesting
To incorporate one or more IF THEN ELSE/ELSEIF
ENDIF statements inside a structure of the same kind.
Network
1 - Part of the PLC configuration, based on the device
type. The number of Networks available is dependant on
the device type.
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.
