Operation The block controls the analogue output (AO1) of a FIO-11 Analog I/O Extension
mounted on slot 2 of the drive control unit.
The block converts the input signal (AO scaled) to a 0...20 mA signal (AO) that drives
the analogue output; the input range AO Min Scale ... AO Max Scale corresponds to
the current signal range of AO Min ... AO Max.
AO Min Scale must be smaller than AO Max Scale; AO Max can be greater or smaller
than AO Min.
AO Min < AO Max
AO Min > AO Max
Inputs Minimum current signal (AO Min): REAL (0...20 mA)
Maximum current signal (AO Max): REAL (0...20 mA)
Minimum input signal (AO Min Scale): REAL
Maximum input signal (AO Max Scale): REAL
Input signal (AO scaled): REAL
Outputs Analogue output current value (AO): REAL
Error output (Error): DINT (0 = No error; 1 = Application program memory full)
