The functions of the analog output module SM 332; AO 4 x 0/4...20 mA are
set
with STEP 7 (refer to /231/) or
in the user program with SFCs (refer to /235/).
The analog output module features default settings for type of output,
diagnostics, interrupts etc. (see Table 3-23).
These default settings are valid if re-parameterization has not been carried
out via STEP 7.
Table 3-37 shows the allocation of the 4 channels to the 4 channel groups of
SM 332; AO 4 x 0/4...20 mA.

Non-connected output channels of the analog output module SM 332;
AO 4 x 0/4...20 mA must be deactivated to ensure no power is applied to
them. You can deactivate an output channel with STEP 7 via the ”output”
parameter block (see Section 3.6.3).
