Structure of data record 1
The figure below shows the structure of data record 1 of the parameters for an analog input
module with 8 channels in 4 groups (e.g. AI 8 x 12 bits). The structure of a module whose
channels are not grouped together is documented in the relevant module description.
You enable a parameter by setting a logic "1" at the corresponding bit of byte 0.
