NTC 10 kOhm Thermokon

With the setting "NTC 10 kOhm Thermokon" and activated Siemens format, the
I/O module converts the resistance measured values of NTC 10 kOhm
Thermokon resistance sensors and outputs them as temperature values.
The temperature values are displayed at a resolution of 1 digit per 0.5 °C.
The status information is depicted in bit 0 to bit 2 and the digitalized measured
value in bit 3 to bit 15.

1) Temperature values below 0 °C are represented in two's complement binary.
2) When short circuit and wire break monitoring is ON (see section "Behavior in the Event of an
Error")
3) When underrange / overrange limit is ON (see section "Behavior in the Event of an Error")
4) Status information: X: Not used, F: Short circuit, wire break, Ü: Overrange
