This object monitors the output value when a source is connected.
Output value is from -32768 to 32767 for 0 V to 5 V on physical analog output.
Output value can be "directly" written (e.g. over Fieldbus) but you have to make sure that there is no source
connected ("Index/sub-index of Analog Output source" = 0). The output value is defined by:
Physical_Analog_Output = (Analog Analog_Output_Offset) * Analog_Output_Gain / 256
