Output ranges of SM 334; AI 4/ AO 2 x 12 bit
The "voltage" output type and "0 V to 10 V" output range are set by default at the module.
You can always use this combination of the output type and range without having to program
the SM 334; AO 4 x 2 Bit in

Unused channels
Set the "disabled" argument at the "measuring method" parameter for unused input
channels. This reduces the module's cycle time.
Always short-circuit unused input channels, and connect these to M
interference immunity of the analog input module.
To take the unused output channels of SM 334; AI 4/AO 2 x 12 Bit off power, always set
"disabled" argument at the "output type" parameter, and leave the connection open.
