4.3.13.2
S5-FB250 Format
With the setting "Resistance measurement 1" (0 Ohm to 5.0 kOhm) and activated
S5-FB250 format, 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 4 Ohm. The status
information is depicted in bit 0 to bit 2 and the digitalized measured value in bit 3
to bit 15.

the Event of an Error")
2) When underrange / overrange limit is ON (see section "Diagnostics" > „Behavior in the Event
of an Error")
3) Status information:

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.
4.3.14.1
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
