Output ranges
You program the output ranges for voltage and current outputs in STEP 7.

Selected Type of Output
Voltage
Current
Default Settings
The default settings of the module are "Voltage" for the output type and "" 10 V"
for the output range. You can use this combination of output type and output range
without parameterizing the SM 332; AO 2 x 12 bits in STEP 7.
Wire-Break Check
The analog output module SM 332; AO 2 x 12 bits carries out a wire-break check
only for current outputs.
Short-circuit test
The analog output module SM 332; AO 2 x 12 bits carries out a short-circuit check
only for voltage outputs.
Substitute values
You can configure the SM 332; AO 2 x 12 bits for the CPU operating mode STOP
as follows: Outputs De-energized, Hold Last Value or Inject Substitute Values. If
you inject substitute values, they must be within the output range.
Special characteristic of substitute values for output ranges 1 to 5 V and
4 to 20 mA
The following special characteristic applies to output ranges 1 to 5 V and 4 to 20
mA:
You have to set the substitute value E500
(refer to Tables 4-35 and 4-37 on pages 4-26 and 4-27).
