Channel groups
The channels of the SM 331; AI 8 x 12 bits are arranged in four groups of two. You
can only ever assign parameters to one channel group.
The analog input module SM 331; AI 8 x 12 bits has a measuring range module for
each channel group.
The table below shows which channels are parameterized as a channel group in
each case. You will need the channel group number to set the parameters in the
user program with an SFC.
