Instructions for use – Ultrasonic sensors series “High-End“
8.1
Sensor synchronization
Multiple ultrasonic sensors of the same type can be synchronized in an application via IO-Link in Synchronization
mode.
Further information is provided in the document “IO-Link parameters for “High End” ultrasonic sensors” (D102012)

Setting
The ultrasonic sensor has 2 outputs with individually adjustable limits. Output 2 is factory set as an analog output
and can be used either as a current output, a voltage output or as a switching output. The user can set an indi-
vidual switch point as well as a double switch point for the switching outputs. The double switch point is used for
window or hysteresis functions. The output behavior of the switching outputs and analog outputs is shown in
Fig. 5. The sensor works automatically once the teach operation has been successfully completed.
Other operating modes (e.g. multiplex, synchronization, enabling and opposed mode) and parameters can be set
via IO-Link.
The following flow chart illustrates the operating steps and the LED indication during the teach-in process.
