Photoelectric Sensors
Red light diffuse reflective energetic BOS 50K-...-PI11-S4 with IO-Link
With Teach Channel: Dynamic Teach. Dynamic Teach-In of both setpoints
Principle
Dynamic teach-in allows you to set the switching point
without interrupting the process.
Typical application:
Sensitivity setup to a moving object to be detected within a
certain distance range. (Window Mode).
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 points SP1 and SP2.

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.
( > 10min: Dynamic Teach is aborted automatically.
Sensor keeps operating with last valid Setpoint set-
tings).
4. Stop Dynamic Teach:
Send System command 0x4A to sensor.
Access Index Value
W 0x0002 0x4A
5. Verify successful sensitivity setup:
Read and verify parameter Teach-In Status with Index
0x003B.
Access Index Value
R 0x003B 0xF4 Dynamic sensitivity setup of SP1
and SP2 successful.
Teach-In State = WAIT FOR
0x07 Teach-In State = ERROR
6. Store and accept Setpoints SP1 and SP2:
Send System command 0x40 to sensor.
Access Index Value
W 0x0002 0x40
7. Verify correct acceptance of SP1 and SP2:
Read and verify parameter Teach-In Status with Index
0x003B.#
Access Index Value
