4.3.2 Effect of the value range on the 2AI U HF analog input
The way electronic modules respond to analog inputs depends on where the input values fall
within the value range. This is illustrated by the table below.
Table 4-6 Response of the analog modules, depending on where the analog input value falls within the range of values
