Teach with background suppression Window mode
A window range is specified by teaching the minimum and
maximum object distance to detect within the setting
range.

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).

Verify whether TP1 has been taught successfully:
Read out and check the parameter Teach-In Status
using Index 0x003B.

Teach
The red LED replies that TP1 was not successfully
taught.
7.
Verify whether TP1 has been taught successfully:
