3 | Description
The following statements can be derived from the graph:
No containment of the analog output (i.e. Sr = 50 mm - gray characteristic line) limits the
n
precision at the analog output to 16 µm.
However, if the analog measuring range is narrowed down to 3 mm or smaller (dark blue
n
characteristic curve), the best possible precision of the sensor can be achieved at any dis-
tance in the measuring range. This is 1 µm to 3 µm.
Interpretation in detail
1. Analog measuring field = 50 mm:
If the analog measuring field is not restricted, the resolution of the analog output limits the
repeatability of the sensor to 16 µm. The gray characteristic curve shows the limitation of the
performance.
2. Analog measuring field = 30 mm:
If the analog measuring field is limited to 30 mm, the resolution of the analog output limits
the repeatability of the sensor to 10 µm. The black characteristic curve shows the limitation
of the performance.
3. Analog measuring field = 10 mm:
If the analog measuring field is limited to 10 mm, the resolution of the analog output limits
the repeatability of the sensor to 3 µm. The light blue characteristic curve shows the limita-
tion of the performance.
4. Analog measuring field = < 3 mm:
If the analog measuring field is restricted to < 3 mm measuring range, the resolution of the
analog output over the entire measuring range does not limit the repeatability. The dark blue
characteristic curve shows the best possible repeatability from 1 µm to 3 µm of the sensor.

IO-Link

The IO-Link distinguishes between the following types of data:
Process data
n
Parameter
n
Diagnostic data
n
Process data
Process data are cyclical data that are transmitted in the IO-Link communication mode with
each query cycle. An explicit query of the data is not necessary. The following process data are
available for the sensor:
Output:
n
▪ Find me (localizing the sensor by activating the LEDs)
▪ Laser on/off
Input:
n
▪ Measured value
▪ Scale of the measured value
▪ Status of the alarm output
▪ Status of the signal quality
▪ Status of the switching output
