30.3.3 Measurements using sensors
In order to measure a sensor's output voltage via an analog input, a
differential voltage measurement is carried out without connecting either
input cable to ground (GND). The signal being measured must fall within the
input's permissible common mode range.

30.4 Diagnostics
Cable break diagnostics will only be run for the analog inputs. The R voltage
reference outputs will be individually monitored for overcurrent,
short-circuits, and an excessively high total current. Object 0x30B5 delivers
the diagnostics – please refer to manual:
