The resolution in the case of the PT 100 is approximately 1/3 °C 10 units correspond to approxi-
mately 1 .
You can use the assignment in Figure 10-25 for the PT 100 resistance sensor.
Linearization of the digital input values is not carried out via the modules. You can linearize the
input values only via the relevant software solution.
