4.3.15 Resistance Measurement 2, 0 Ohm ... 1.2 kOhm, ID 15
No short-circuit detection for resistance measurements!
For sensor types "Resistance measurement 1" and "Resistance measurement 2",
short-circuit detection is not technically possible.
4.3.15.1

Default Format

With the setting "Resistance measurement 2" (0 Ohm to 1.2 kOhm), the I/O
module outputs the measured resistance values of the sensors directly.
The resistance values are displayed at a resolution of 1 digit per 0.05 Ω in one
word (16-bit). The maximum number range viewable in one word in two's
complement representation ranges from −32768 to +32767. The number range
used depends on the sensor type set and the resolution of the process value. For
the setting "Resistance measurement 2", the possible numerical range
corresponds to the defined measuring range of 0 Ohm to 1.2 kOhm and ranges
from 0 to +24000 accordingly.
