Dynamic Teach (Smart Sensor Profile Spec.)
With this process, no static teach points are recorded,
unlike with the previous methods; rather, multiple
measurement values are recorded over a defined period of
time. Measurement value acquisition is started with the
Dynamic Teach SP1 Start
system command and ended
with
Dynamic Teach SP1 Stop
. If all recorded
measurement values were in the valid detection range, the
switching point calculation is started. For this purpose, the
minimum and maximum values are determined. The
average value of these two extrema is used to form the
new switching point (setpoint). The maximum acquisition
time is 5 minutes. After 5 minutes without a Stop
command, the event 0x8DC0 Teach Timeout is set.

Dynamic Teach in Two-Point Mode
Dynamic Teach (Balluff spec.)
This teach process is only available in Two-Point and
Window Mode. As with the previous process, the
measurement values are dynamically recorded over a
defined period of time. Measurement value acquisition is
started via the
Dynamic Teach SP1 Start
system
command, but ended here with
Dynamic Teach SP2 Stop
.
If all recorded measurement values were in the valid
detection range, the switching point calculation is started.
The minimum and maximum values are determined for this
purpose. Unlike the previous process, the maximum value
is used as switching point 1 (SP 1) and the minimum value
as switching point 2 (SP2). The maximum acquisition time
is again 5 minutes. After 5 minutes without a Stop
command, the event 0x8DC0 Teach Timeout is set.
