Standard function blocks
268
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.
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)
