InformationModel.MakeVariable(browseName, dataTypeId, arrayDimensions)

Creates a project variable derived from the BaseDataVariableType (base variable), which contains the data type indicated by the second argument and returns a corresponding IUAVariable C# object. Using the third argument (optional), it is possible to create an array, specifying its type and size.

static IUAVariable MakeVariable(QualifiedName browseName, NodeId dataTypeId, uint[] arrayDimensions);

Arguments

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

The following example shows an API that creates an analog variable (MyVar) that contains floating data:

var myVar = InformationModel.MakeVariable("MyVar", OpcUa.DataTypes.Float);
Owner.Add(myVar);

The following example shows an API that creates a MyArray array with three cells:

var arrayDimensions = new uint[1];
arrayDimensions[0] = 3
var myVar = InformationModel.MakeVariable("MyArray", OpcUa.DataTypes.Int32, arrayDimensions);
Owner.Add(myVar);
