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.
Instructions
Precondition:
Sensor is installed, aligned to the moving target, and
operated in IO-Link mode.
Procedure:
1. Start Dynamic Teach:
Send System command 0x47 to sensor.

2. Wait for a minimum of one process cycle is completed.
( Dynamic Teach is aborted in case no object has been
detected within 1 min or Teach has not been confirmed
within 10 min. Sensor keeps operating with last valid
Setpoint settings).
3. Stop Dynamic Teach:
Send System command 0x4A to sensor.
