Output value range error “Out of Range” (OoR)
A
:
– The set output value overstepps or undercuts the limit of the
nominal range (limit values according to parameterization).

3
Overflow / Underflow (OUFL)
A
:
– The set output value exceeds the output range (limit values
according to parameterization). The module cannot transmit
this value. The output value is the maximum or minimum
value which can be outputted.

Hardware error (HW Error):
– Exampels: CRC error, calibration errors…
– The output value of the analog value is “0”.
