Simulation

This function activates the measuring input simulation (simulation=active). Measured result

arrived is set and allocated to the programmed measured value as a measured result.
If the simulation mode is active on the measuring input, the simulated measured value is

entered in Measuredvalue1 using the function _enableMeasuringInput (trigger), and

state=trigger_occured is set.
