Save and apply switchpoint SP1 and SP2: Send
system command 0x40 to the sensor.

9. Check whether SP1 and SP2 were successfully taught:
Read out and check the parameter Teach-In Status
using Index 0x003B.

Sensor principle: background evaluation
The background is taught. Objects in front of the
background are detected. This allows for example
reflective objects to be reliably detected against a
background.

Procedure in IO-Link mode:
1.
Align sensor with the background
2.
Select Teach-In channel:

3.
Teach point (TP1 for SP1). Send system command
0x41 to sensor.
Access Index Value Meaning
W 0x0002 0x41 SP1 Single Value
Teach
If the red LED comes on, TP1 could not be taught
(alignment is unsuitable or the background is outside
the detection range).
4.
Verify whether TP1 has been taught successfully:
Read out and check the parameter Teach-In Status
using Index 0x003B.
Access Index Value Meaning Result
R 0x003B 0x14 TP1 was
successfully
taught
