ActualValue: ABN646#001 parameter indicating the discrete value of the not simulated discrete process variable of a device.
SimulationValue: ABN637#001 defines parameter indicating the simulated discrete value of a variable, which can have multiple states.
SimulationState is defined by IRDI as ABN611#001 which states “defines parameter indicating the state of simulation” and used also to enable/disable simulation.
