Multi-function sensor with additional functions
BOS 21M-UUI-RP30-S4
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.

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
SP2 SP1
TP2 TP1 TP2 TP1
Example: 0 = IDLE
0 = TP1 for SP1 not 1 = SP1 SUCCESS
taught or not successful 2 = SP2 SUCCESS
3 = SP12 SUCCESS
1 = TP1 for SP1 4 = WAIT FOR COMMAND
successfully taught 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.
