Photoelectric Sensors
Red light diffuse reflective energetic BOS 50K-...-PI11-S4 with IO-Link
With Teach Channel: Dynamic Teach. Dynamic Teach-In of 1 setpoint
Principle
Dynamic teach-in allows you to set the switching point
without interrupting the process.
Typical application: Sensitivity setup to a process running
perpendicular to the light beam of the sensor
During the teach procedure, which begins with the Start
command and ends with the Stop command, the sensor
carries out measurements and determines the minimum
and maximum of the obtained values. The Teach Apply
command determines the switching point SPy.

Instructions
Dynamic Teach is explained for SP1 as an example.
The same sequence can be applied for SP2 with the
corresponding instruction set.
Precondition:
Sensor is installed, aligned to the running process and
operated in IO-Link mode.
Procedure:
1. Set Teach-In Channel.

2. Start Dynamic Teach:
Send System command 0x47 to sensor.
Access Index Value
W 0x0002 0x47
3. Wait for a minimum of one process cycle is completed.
(>10 min: Dynamic Teach is aborted automatically.
Sensor keeps operating with last valid Setpoint set-
tings).
4. Stop Dynamic Teach:
Send System command 0x48 to sensor.
Access Index Value
W 0x0002 0x48
5. Verify successful sensitivity setup:
Read and verify parameter Teach-In Status with Index
0x003B.
Access Index Value

0x07 Teach-In State = ERROR
6. Store and accept Setpoint SP1:
Send System command 0x40 to sensor.
Access Index Value
W 0x0002 0x40
7. Verify correct acceptance of SP1:
Read and verify parameter Teach-In Status with Index
0x003B.
Access Index Value
R 0x003B 0x01 SP1 accepted successfully.
Teach-In State = SP1 SUCCESS
