Setting the measuring range with the measuring range
module
Measuring range module
A measuring range module is located on the left of the input/output module. The
measuring range module is used to set the method of measuring on the analog
inputs, that is, to choose between voltage and current measuring.
Settings
The measuring range module can be set for “A”, “C” or “D”.
The default setting is “D”.
Table 1-1 shows the allocation of measuring range module settings to possible
connections of the analog inputs.
The measuring range is set using HW Config. You can select from different current
or voltage ranges (see Section 3.2).
The required measuring range module setting is also displayed in HW Config.
