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);
