Default Settings Of The Sm 331; Ai 8 X 12 Bits Using Measuring Range Modules - Siemens SIMATIC S7-300 Reference Manual

Analog Modules
Default settings for measuring range module
The measuring range modules are preset to "B" (voltage; " 10 V) when the
module is supplied.
To use the following preset measuring methods and measuring ranges, you only
have to change the measuring range module to the corresponding setting.
Parameter assignment in STEP 7 is not necessary.
