Signal quality
The signal quality indicates the stability of the measurement. A meaningful value is
output only if the distance between the device and the measuring object is constant.
This value can be provided as part of the process data (process data format 4) via the
IO-Link interface.
3.8.4
Alarm output
The digital outputs can be configured as a switching function for alarm signaling:
Output of a switching signal if the device cannot generate a measured value (e.g., no
object in the measuring range or remission of the measuring object too low)\.
This error output is particularly useful if the setting is activated whereby the device
retains the last valid measured value as soon as no measurement is possible (
"Alarm function - hold", page 21
). The output behavior can be inverted.
Likewise, the status of the alarm function can be provided via the status bits (bit 0 or
bit 1) as part of the process data via the IO-Link interface.

Multifunctional input MF
The laser can be switched off and on via the MF input. This can be used for diagnostic
purposes to detect device faults with the help of an evaluating controller and thereby
achieve a DC of up to 60% in the system network.
3.8.6
Find me!
The “Find me!” function makes it fast and easy to find a device that is installed in a
machine or system.
When the “Find me!” function is activated, the two yellow LEDs on the device flash (Q1
and Q2) and the sender laser flashes with a frequency of 5 Hz. When the function is
being used, it is not possible to perform a correct distance measurement. If the device
is switched off and back on when the “Find me!” function is activated, the “Find me!”
function will then no longer be active.
