6.3 Process data
The BIP outputs 2-byte process data via the IO-Link
interface. The process data structure is described in the
Smart Sensor Profil Ed.2.

Measurement value
The measurement value represents the position of the
magnet in μm and consists of a signed 16-bit value.

Measurement value and areas
If the magnet lies outside the measurement range, the
process data variable is assigned the following values:
– No Measurement data 32764
– Out of Range positive 32760
– Out of Range negative –32760
The detection range is 17000 µm at delivery (detection
range = measuring range).
