SpecView supports Active-X objects on it’s screens.
There are two main types of Active-X controls: Graphical and non-graphical
Graphical Active-X Controls have some kind of graphical representation and function, for example, FactorySoft’s SymbolFactory can be used to create screens with many more symbols and shapes than SpecView natively supports
Non-Graphical Active-X Controls have no visual representation - instead they act like ‘function blocks’, processing input data in some way to produce some kind of output.
Both sorts of Active-X Control can be positioned on the screen and have their properties linked either to constants or to live runtime variables. Similarly, the results of any calculations performed by the Active-X Control can end up in other live data points (e.g. Setpoints or User Variables)
Some Controls supplied by SpecView and some third parties are licensed using a SpecView scheme. There are currently 3 classes of licensed controls: Class1, Class2 and Class3. An option needs to be purchased to allow any given class or classes of licensed controls to work, see the ordering codes and the list of Active-X controls (below) for more details.
Currently available Active-X controls from SpecView and selected third parties:
Non-licensed (requires only Active-X option in dongle:
Class 1 Controls: (requires both Active-X option and Class 1 option - A1)
Class 2 Controls: (requires both Active-X option and Class 2 option - A2)
Class 3 Controls: (requires both Active-X option and Class 3 option - A3)
