6.7.2 Measurement types and ranges
Introduction
Module SM 331; AI 8 x 12 Bit has measuring range modules
The measurement type and range is configured at the "measuring range" parameter in
STEP 7 .
The default setting of the module is "voltage" measurement with "± 10V" range. You can use
these default settings without having to program the SM 331; AI 8 x 12 Bit in
STEP 7 .
Measuring range modules
You may have to change the position of the measuring range modules to suit the
measurement type and range (see the chapter
Setting the measuring types and ranges of
analog input channels
). The necessary settings are also available on the module's imprint.
Mark the position of the measuring range module on the front door (see figure).
