Potentiometer

With the setting "Potentiometer", the I/O module outputs the resistance ratio
between the connections +R1/−R1 and −R1/−R3 or +R2/−R2 und −R2/−R4.
Potentiometers of 1 kOhm ... 5 kOhm can be used.
The set values are displayed at a resolution of 1 digit per 0.1 % in one word (16-
bit). The possible numeric range corresponds to the defined measurement range
of 0 % ... 100 %.

No error detection for the "Potentiometer" setting!
Detection of a wire break or short circuit is not possible depending on the model.
An overrange or underrange is also not possible depending on the sensor.
Accordingly, the status byte is always 0x00.
