60 Process Image
4.4.10 Resistance Measurement 10 Ohm ... 1.2 kOhm
With the setting "Resistance measurement 10 Ohm ... 1.2 kOhm" and activated
Siemens format, 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.
The status information is depicted in bit 0 ... bit 2 and the digitalized measured
value in bit 3 ... 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
