InformationModel.MakeVariable<T>(browseName, dataTypeId, arrayDimensions)

Create a project variable, derived from the specified
<T>
 type, which contains the data type indicated by the second argument. It returns a C# object of the specified
<T>
 type corresponding to the project variable created. Using the third argument (optional), it is possible to create an array, specifying its type and size.
TIP: At design time, the API functions only if the specified type is a predefined type (contained in the FTOptix modules).
static T MakeVariable<T>(QualifiedName 
browseName
, NodeId 
dataTypeId
, uint[] 
arrayDimensions
);

Arguments

T
IUAVariable
 C# class, corresponding to the C# object class to return and to the variable type from which the new variable is derived.
browseName
 (QualifiedName)
The
BrowseName
 of the new variable.
dataTypeId
 (NodeId)
The Data type contained in the new variable.
TIP: A node inside the
DataTypes
 class represents the Data type. For example,
OpcUa.DataTypes.Boolean
.
arrayDimensions
 (uint[ ])
Optional. The size of the Array.

Returns

IUAVariable
A C# object that corresponds to the project variable created.

Examples

Below is an example in which a
Speed2
 variable of the
Speed
 type is created and returns a
Speed
 C# object:
var myVar = InformationModel.MakeVariable<Speed>("Speed2", OpcUa.DataTypes.Int32);
Owner.Add(myVar);
