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

26.4 Diagnostics
Cable break diagnostics will only be run for the analog inputs. The R voltage
reference outputs will be individually monitored for overcurrent, short-cir-
cuits, and an excessively high total current. Object 0x30B5 delivers the diag-
nostics – please refer to manual „CANopen Gateway XN312-GW-CAN“,
MN050003.
