Parameter data and data formats for the process data

All parameters must always be transferred from the control to the I/O module.
6.3.1

Input module 2AI2M12E

The analog inputs are assigned to the following addresses via input parameters:

See "6.3.2 Data formats and value ranges of input module 2AI2M12E"
The default setting for the "input channel configuration" parameter (bit 7–bit 0) is 0. If a parameter
contains the bit combination "reserved" (bit 7, bit 6, bit 2–bit 0), the default setting 0 is automatically
assigned internally for these bits.
