6.3.1 Measuring methods and ranges
Introduction
Use the "measuring range" parameter in
STEP 7
to set the measuring method and
measuring ranges.
The "voltage" measuring method and "± 10V" measuring range are set by default at the
module. You can use those default settings without having to program the SM 331; AI 8 x 16
Bit in
STEP 7
.
