User Function Library Document
Users can create functions in customized libraries which can be exported and imported to any project created in SmartView.
In these libraries the user will be able to create functions to be used in the application. An example is to create a customized math library to help in the execution of the application.
The libraries are made using the C# programming language and it CANNOT have any tag in it. If you need tag values to be calculated, you will need to pass it as parameters of the function or return a value.
There is also a System Function Library which allows you to select a tag value or to change its value. Please check SVTags function library.
To use the libraries made, the user will have to set an event as following:
LibraryName.FunctionName(pameter1, parameter2, ...);
When the user configures the call of the event, it is possible to use tag or static values.
Topics:
Example:
In this example, the tag "TagFunction" will store the result from the function "Sum", that will sum two values passed in the parameter, created in the "CustomizedMathLibrary".
|
@TagFunction = CustomizedMathLibrary.Sum(10,5);
|
In this example, "TagFunction" will store the result from the function "Sum", that will sum two values passed in the parameter (in this case one tag and one static value), created in the "CustomizedMathLibrary".
|
@TagFunction = CustomizedMathLibrary.Sum(@TagParameter,5);

Navigation:
The combobox in the top right of the user function library can be used to navigate between the functions created in that document.
When you select a function in the combobox the focus will go to the selected function.
