The ConfigureOpcUa...Item activities register a single variable within an [[Activity:CreateOPCUAConnection (Activity)|OPC UA Connection]]. Only registered variables can be accessed later on with [[Activity:AccessOPCUAVariable (Activity)|AccessOPCUAVariable]] activities.
This page is a generic description covering all activities available for registering Opc Ua variables, namely
* [[Activity:ConfigureOpcUaAnalogItem_(Activity)|ConfigureOpcUaAnalogItem]]: for analog values
* [[Activity:ConfigureOpcUaDiscreteItem_(Activity)|ConfigureOpcUaDiscreteItem]]: for analog values (e.g. boolean)
* [[Activity:ConfigureOpcUaMultiStateDiscreteItem_(Activity)|ConfigureOpcUaMultiStateDiscreteItem]]
* [[Activity:ConfigureOpcUaTwoStateDiscreteItem_(Activity)|ConfigureOpcUaTwoStateDiscreteItem]]
Each of the above activities can be used for a certain Opc Ua variable type, respectively.
