5.25.1 Commissioning the SM 432; AO 8 13 Bit
Parameter
You will find a description of the general procedure for assigning parameters to
analog modules in Section 5.7.
You will find an overview of the programmable parameters and their default values
in Table 5-43, on page 5-42.
Assigning Parameters to Channels
You can configure each output channel of the SM 432; AO 8 13 Bit individually.
You can thus assign different parameters to each output channel.

13 Bit
Wiring the Analog Outputs
You can wire the outputs as voltage or current outputs, or disable them. You wire
the outputs by means of the “Type of Output” parameter in STEP 7.
Unused Channels
To ensure that output channels of the SM 432; AO 8 13 Bit remain de-energized,
you must disable the “Type of Output” parameter and leave the terminal open.
Output Ranges
You program the output ranges for voltage and current outputs in STEP 7.

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 432; AO 8
13 Bit in STEP 7.
