TEACHING
If settings are configured simultaneously on the main unit side and on the IO-Link
communication side, the settings that are applied last will be enabled.
2-point teaching
● This is the basic teaching method.

1-point teaching (Window comparator mode)
● This is mode is used for setting the threshold range for the distance from the ref-
erence value of the sensing object, by performing 1-point teaching. This mode is
used for sensing within the threshold range.
● When performing 1-point teaching (window comparator mode), preset "Window
comparator mode 1" in the sensing output setting of the PRO mode. For the set-

2-point teaching (Window comparator mode)
● This is method to set the threshold range by conducting the 2-point teaching.
● When performing 2-point teaching (window comparator mode), preset "Window
comparator mode 2" in the sensing output setting of the PRO mode.
For the setting, refer to "
● When conducting teaching, use sensing objects (P-1 and P-2) whose distance are
different from each other.
Threshold 1_SL
3-point teaching (Window comparator mode)
● This is the method to perform 3-point teaching (P-1, P-2, P-3) and to set the threshold range
by setting threshold 1_SL in the mid-point between the 1st time and 2nd time, and threshold
2_SL in the mid-point between the 2nd time and 3rd time as shown in the following figure.
● When performing 3-point teaching (window comparator mode), preset "Window
comparator mode 3" in the sensing output setting of the PRO mode.
For the setting, refer to "
● When performing teaching, use sensing objects (P-1, P-2, P-3) with different distance.
● After teaching, P-1, P-2 and P-3 will be automatically rearranged from the smaller value.
Span adjustment in rising differential mode or trailing differential mode
● This mode is used to cancel the gradual changes in the measured value, and to
only detect sudden changes.
● W hen performing rising differential mode or trailing differential mode, preset "Ris-
ing differential mode" or "Trailing differential mode" in the sensing output setting of
the PRO mode. For the setting method, refer to "
● T he threshold can be set by using the threshold value fine adjustment function.
For the threshold value fine adjustment function, refer to "
