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

Creates a project variable of the type indicated by the third argument, and 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 fourth argument (optional), it is possible to create an array, specifying its type and size.

static T MakeVariable<T>(QualifiedName browseName, NodeId variableTypeId, NodeId dataTypeId, uint[] arrayDimensions);

Arguments

T: IUAVariable C# class, corresponding to the class of the C# object to return.
browseName (QualifiedName): The BrowseName of the new variable.
variableTypeId (NodeId): The Variable type from which the new variable type is derived.

Tip: A node inside the VariableTypes class represents the Data type. For example,FTOptix.CoDeSys.VariableTypes.Tag.
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.

Example

var myTag = InformationModel.MakeVariable<FTOptix.CoDeSys.Tag>("CodesysTag", OpcUa.DataTypes.UInt16);
