8.2.2 Definition ToC Previous Next index

The AnalogSignalVariableType can be used to model any analog signal type. It extends the AnalogUnitRangeType defined in OPC 10000-8 to add additional information such as values for simulation and damping as well as dictionary references.

The ActualValue contains the unsimulated value during a simulation and SimulationValue contains the value to be used during simulation, as illustrated in Figure 10. The Value attribute always represents what is being reported by the Variable.
