Table 108: Setting: Resistance Measurement (Potentiometer) - WAGO 750-489 Manual

WAGO-I/O-SYSTEM 750
750-489 4AI RTD/TC/Strain Gauge Ex i
4.7.7.2 S5-FB250 Format
With the "Potentiometer" setting and S5-FB250 format enabled, the I/O module
outputs the resistance normalized to 2000. The defined measuring range of
0 % ... 100 % corresponds to a possible process value of 0 ...+2000.
Note:
Be aware that the status information is represented in bit 0 ... bit 2 and the
digitized measured value in bit 3 ... bit 15. Therefore, the normalized measured
value is shifted by three bits in the process image!
Thus a normalized measured value of +2000 corresponds to a process value of
+16000
