Measurement types and ranges

Introduction
The module is set to voltage measurement type with measuring range ±10 V by default. You
need to reassign the module parameters with STEP 7 if you want to use a different
measurement type or range.
Deactivate the input if it is not going to be used. The module cycle time is shortened and the
interference factors that lead to failure of the module (for example, triggering a hardware
interrupt) are avoided.
Measurement types and ranges
The following table shows the measurement types and the respective measuring range.
