WAGO-I/O-SYSTEM 750
750-451 8 AI RTD
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.

S5-FB250 Format
With the setting "Resistance measurement 2" (0 Ohm to 1.2 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 0.5 Ohm. The
status information is depicted in bit 0 to bit 2 and the digitalized measured value
in bit 3 to bit 15.
