5.8.2 Parameters of analog input modules
Overview
Analog input modules use a subset of the parameters and value range listed in the table below,
based on their functionality. For information on subsets "supported" by specific analog
modules, refer to the section dealing with the relevant module.
The defaults apply if you have not set any parameters in
STEP 7 .
