4 Functions
4.1 Output function hysteresis
The hysteresis keeps the switching state of the output stable if the measured value varies about the
sensing range. Both outputs [OUT1] and [OUT2] can be set as hysteresis function. Hysteresis function
(
4.2 Output function window
The window function enables the monitoring of a defined acceptable range. Both outputs [OUT1] and
[OUT2] can be set as window function. Window function (
4.3 Analogue function mode
An analogue signal that is proportional to the distance can be output at [OUT2]. Scaling of the
measuring range (analogue output) (
4.4 Switch off the laser
For safety and maintenance purposes the laser of the unit can be temporarily switched off via the input
on pin 5.

4.5 IO-Link
IO-Link is an internationally standardised IO technology (IEC 61131-9) for communicating with
sensors and actuators.
General information about IO-Link can be found at
IO Device Description (IODD) with all parameters and process data of the unit can be found at
In the factory setting the unit is in SIO mode (standard input-output). When connected to an IO-Link
master, the unit automatically switches to IO-Link mode.
IO-Link offers the following advantages:
•
Noise-immune transmission of all process values.
•
Parameter setting during operation or point-to-point at the desk.
•
Detection of connected units.
•
Freely definable parameters to identify the units in the plant.
•
Additional parameter and diagnostic functions (events) compared to the SIO mode.
•
Data storage: Automatic transfer of parameters when a unit is replaced.
•
Logging of parameter sets, process values and events.
