Sensor function principle and Teach-In of the
switchpoints through IO-Link
The sensor supports two sensor function principles. The
IO-Link parameter 0x00BB can be used to toggle between
background suppression and background evaluation.
A static Teach-In procedure in Single Value Teach is used
for teaching the switchpoints. In parameter 0x003B
Teach-In status the current status of the Teach-In
procedure is indicated.
Teach flags Teach state
SP2 SP1
TP1 TP1
Example for:
0 = TP1 for SP2 not
taught or not successful
1 = TP1 for SP2
successfully taught
0 = IDLE
1 = SP1 SUCCESS
2 = SP2 SUCCESS
3 = SP12 SUCCESS
4 = WAIT FOR COMMAND
5 = BUSY
6 = reserved
7 = ERROR
Tab. 2: Teach-In Status
Sensor principle: background suppression
The object is taught.

Teach-In background suppression Single Point Mode
The switchpoint can also be taught in SIO mode
using the button (see page 4).
If the Teach-In procedure is not completed, it
will be automatically canceled after 10 min. and
all the original settings are retained.
Teaching switchpoint in IO-Link mode:
1. Position the object in the beam path.
2. Select Teach-In channel:
Access Index Value Meaning
W 0x003A 0x00 Standard SSC1
W 0x003A 0x01 SSC1
W 0x003A 0x02 SSC2
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 object 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
