Channel groups
The channels of SM 331; AI 8 x 14 Bit High Speed are arranged in four groups of two
channels. You can assign parameters only to one channel group.
SM 331; AI 8 x 14 bits High Speed is equipped with one measuring range module per
channel group.
The table below shows the relevant configuration of channel groups. The channel group
number is required to program SFC parameters in the user program.
