2.5.7. Event configuration
Temperature events transmitted over the IO-Link interface are turned off by default in the sensor. If the user wants
to get information about critical temperatures detected in the sensor application, this parameter allows the
following 4 events to be enabled or disabled:
• Temperature fault event: the sensor detects temperature outside the specified operating range.
• Temperature over-run: the sensor detects temperatures higher than those set in the Temperature
Alarm threshold.
• Temperature under-run: the sensor detects temperatures lower than those set in the Temperature
Alarm threshold.
• Short-circuit: the sensor detects if the sensor output is short-circuited.
2.5.8. Quality of run QoR
The Quality of run informs the user about the actual sensor performance, evaluating the following parameters:
Maximum signal, Minimum signal, Hysteresis, SP and Safe Limits.
The value for QoR can vary from 0 ... 255 %.
The QoR value is updated for every detection cycle.
Examples of QoR is listed in the table below.

Explanation
Excellent sensing conditions, the sensor is not expected to require mainte-
nance in the near future.
Good sensing conditions, the sensor performs as well as when the setpoints
were taught or set-up manually with a safety margin of twice the
standard hysteresis.
• Long term reliability is expected under all environmental conditions.
• Maintenance is not expected to be required.
Average sensing conditions
• Due to environmental conditions, the reliability of the measurement values
is reduced and maintenance is required in order to improve the detection
behavior.
• If the environmental conditions remain stable, reliable detection can be
expected for the near future.
Unreliable sensing conditions, sensor does not work correctly, immediate
maintenance required.
