2. Analogue input module CPX−2AE−U−I
Channel parameters: Signal range channel x
4828 + m * 64 + 8
Function no.
Description For the individual channels of the analogue input modules, the signal ranges of
the analogue inputs can be set independently of each other.

Remark Bits 0/1 as well as 4/5 represent the status of the DIL switches for setting the
signal range.
With bits 2/3 and 6/7 other signal ranges can be parametrized irrespective of
the DIL switch setting.
Modified parameter settings have precedence over the DIL switch settings.
The setting of the DIL switches is carried out with the presetting (bit 2/3 = 0;
bit 6/7 = 0).
