Measuring ranges for thermoresistor

Introduction
The following tables contain the digitized analog values for the measuring ranges of the
analog input modules.
Since the binary representation of the analog values is always the same, these tables
contain only a comparison of the measuring ranges with the units.
Measured values in the event of wire break dependent on enabled diagnostics for resistance
measurement
The following extensions exist for the measuring ranges Temperature sensor Pt xxx
Standard and Climatic, Ni xx Standard and Climatic, Cu 10 Standard and Climatic:
