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);
