VBScript interfaces

The following table provides a summary of the VBScript interfaces:

The following illustration shows the scope of each VBScript interface and the order in which they are scanned:

The illustration shows that the Global Procedures are shared by the Graphic Module and the Background Task. However, the other VBScript interfaces are either from the Graphic Module or from the Background Task, and they do not share variables or procedures between them. They are independent of each other.

Note: Although the Graphics Script is scanned before the Screen Scripts, the procedures and variables declared in the Graphics Script interface are NOT available for any script interface configured on the screens. You must use the Global Procedures interface to implement procedures that must be available for all screens.

When writing your code in a VBScript interface, you can access any tag from the tags database or any function from the Built-in Scripting Language by applying the "$" prefix to the tag/function name, as in the examples below:

$Time 'Returns the value of the tag Time from the tags database

$MyTag 'Returns the value of the tag MyTag from the tags database

$Open("main") 'Executes the Open() built-in function to open the "main" screen

Therefore, you can create scripts using built-in functions, tags from the tags database, VBScript functions, VBScript variables, ActiveX properties, methods or events, and any other interface available. The tags are shared by all modules, including the Graphic Module and the Background Task.
