Sensor function principle
The sensor supports four sensor function principles. The
IO-Link parameter SensorPrinciple 0x00BB can be used
to select between diffuse energetic sensor, diffuse sensor
with background suppression, retro-reflective and through-
beam (emitter or receiver).
The sensor is factory set to energetic diffuse. To implement
the through-beam function two units are required, with one
used as the emitter and the other as receiver.
Changing the sensor function principle takes
maximum 1500 ms.
Switch mode
In IO-Link mode the switching function can be configured
using the parameter 0x003D SwitchpointConfiguration .
The sensor can be operated using switching mode Single
Point , Window or Two Point . In Single Point Mode only the
first switchpoint SP1 is active. In Window Mode both
switchpoints SP1 and SP2 are active and form a window.
In Two Point Mode both switchpoints SP1 and SP2 are
active, where SP1 and SP2 form the hysteresis.

Fig. 6: Switch mode
Switch mode (continued)
Two static teach-in procedures ( Two Value Teach and
Single Value Teach ) or a dynamic teach-in procedure
(Dynamic Teach) can be used to teach the switchpoints
SP1 and SP2 in IO-Link mode.
Teach-In procedure
The current status of the teach-in procedure is indicated in
the parameter Teach-In Status .
Teach Flags Teach State
SP2 SP1
TP2 TP1 TP2 TP1
Example:
0 = TP1 for SP1 not
taught or not successful
1 = TP1 for SP1
successfully taught
0 = IDLE
1 = SP1 SUCCESS
2 = SP2 SUCCESS
3 = SP12 SUCCESS
4 = WAIT FOR COMMAND
5 = BUSY
6 = reserved
7 = ERROR
Tab. 2: Teach-In Status
Teach-in is automatically canceled 10 min. after
start.
The teach-in sequences are explained using
SP1. The same sequence applies for SP2 using
the corresponding commands.
Prerequisite:
The sensor is mounted, aligned, and in IO-Link
operation.
