Appendix A Glossary 40 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.
