2.6. Sensor Specific adjustable parameters
Besides the parameters directly related to output configuration, the sensor also have various internal
parameters useful for setup and diagnostics.
2.6.1. Selection of local or remote adjustment
It is possible to select how to set the sensing distance by either selecting the Teach-button or Teach-
by-wire using the external input of the sensor, or to disable the Teach-button to make the sensor
tamperproof.
2.6.2. Process data and variables
When the sensor is operated in IO-Link mode, the user has access to the cyclic Process Data Variable.
By default the process data shows the following parameters as active: 16 bit Analogue value, Switching
Output1 (SO1) and Switching Output 2 (SO2).
The following parameters are set as Inactive: SSC1, SSC2, DA1, DA2, TA, SC.
However by changing the Process Data Configuration parameter, the user can decide to also enable
the status of the inactive parameters. This way several states can be observed in the sensor at the
same time.

2.6.3. Sensor application setting
The sensor has 4 pre-settings depending on the application:
• Full scale range: the setpoints of the sensor can be adjusted at full scale and the sensing speed
is set to maximum
• Liquid level: this is to be used for slow moving objects with a high dielectric value such as in the
detection of water-based liquids. When this function is selected the teach and Teach-button settings
are optimized to high range scaling.
In this mode the "Filter Scaler" is set to 100
• Plastic Pellets: this is to be used for slow moving objects with a low dielectric value such as in
the detection of plastic pellets. When this function is selected the teach and Teach-button settings
are optimized to low range scaling.
In this mode the "Filter Scaler" is set to 100.
• High-speed mode: For application requiring fast detection the "High-Speed Mode" can be
selected. "High-Speed Mode" has significantly higher detection speed compared to "Normal
Mode", however EMC robustness is lower than "Normal Mode". Therefore "High-Speed Mode" is
not recommended in environments with high amounts of electromagnetic interference.
