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 group0.

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.
