4.3.10 Resistance Measurement 10 Ohm ... 5.0 kOhm
With the setting "Resistance measurement 10 Ohm ... 5.0 kOhm", the I/O module
outputs the resistance measured values of the sensors directly.
The resistances values are displayed at a resolution of 1 digit per 0.5 Ω in one
word (16-bit). The possible numeric range corresponds to the defined
measurement range of 10 Ω ... 5.0 kΩ.

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")
