Assigning parameters to channels
You can configure each output channel of the SM 332; AO 2 x 12 bits individually.
You can thus assign separate parameters for each output channel.
When you set the parameters with SFCs in the user program, the parameters are
assigned to channel groups. Every output channel of the SM 332; AO 2 x 12 bits is
assigned to a channel group in this instance – in other words, for example output
channel 0 = channel group0.
Note
If you modify output ranges when the analog output module SM 332; AO
2 12 bits is in operation, incorrect intermediate values can arise across the
output.
Diagnostics
You will find the diagnostic messages that are grouped under the “group diagnosis”
parameter in Table 4-47, on page 4-73.
4.29.2 Output Ranges of the Analog Output Module SM 332;
AO 2 x 12 bits
Connecting the analog outputs
You can connect the outputs as voltage or current outputs, or disable them. You
perform connection of the outputs with the “output type” parameter in STEP 7.
Unused Channels
So that unused output channels of the SM 332; AO 2 x 12 bits remain
de-energized, you must set the “output type” parameter to “disabled” and leave the
terminal open.
