2.7.11. Maintenance event counter
The sensor logs how many times the event counter have asked for maintenance, the maximum number
of events to be recorded are 2 147 483 647 times. This parameter is updated once per hour and can
be read from an IO-Link master.
2.7.12. Download counter
The sensor logs how many times the parameters have been changed in the sensor, the maximum
number of changes to be recorded are 65 536 times. This parameter is updated once per hour and
can be read from an IO-Link master.
NOTE!
The temperature measured by the sensor will always be higher than the ambient temperature, due to
internal heating.
The difference between ambient temperature and internal temperature is influenced by how the sensor
is installed in the application. If the sensor is installed in a metal bracket the difference will be lower
than if the sensor is mounted in a plastic one.

4. Commissioning
50 ms after the power supply is switched on, the sensor is operational.
If it is connected to an IO-link master, no additional setting is needed and the IO-Link communication
starts automatically after the IO-Link master sends a wakeup request to the sensor.
