Switching point
If the Distance to object (“DtO (1point)”) switching mode is selected, the required
settings can be taught in or set manually. These are described in the following.
NOTE
If the sensor is unable to measure (e.g. the object is in a blind spot of the sensor, there
is too little remission or light reflection), a switching signal is output in the “Distance
to object” (“DtO (1point)”) switching mode, which corresponds to the expected behavior
with the maximum distance.
NOTE
The switching mode and the settings can be changed by executing a teach function by
means of a multifunctional input (
see "Multifunctional input (“MF Input”)", page 57 ) or
IO-Link ( see "Operation via IO-Link", page 21 ).
NOTE
When changing between the “Distance to object” (“DtO (1point)”) and “Switching win‐
dow” (“Window”) switching modes, it is possible that the setting for the previously
selected logic and/or the switching point setting will change.
6.4.1.1.2 Teachable settings (“Teach”)
Two teach functions are available for the “Distance to object” (“DtO (1point)”) switching
mode.
Teach function Description
Q
1
You can use the teach function “Q
1
” to teach in a single switching point
for the “Distance to object” (“DtO (1point)”) switching mode. In this case, a
signal is output if the switching point that has been taught in is undershot.
Thus the output acts as High Active (
see figure 9, page 23 ).
Q
1
not You can use the teach function “Q
1
not” to teach in an inverted logic for the
“Distance to object” (“DtO (1point)”) switching mode. In this case, a signal is
output if the switching point that has been taught in is exceeded. Thus the
output acts as Low Active (
see figure 10, page 23 ).
