Cause
IO-Link communication
1. IO-Link communication
2. Change of the configuration
3. Short-circuit
a)
Insufficient alignment
b)
Contamination of the
optical surfaces
c)
Particles in the light
beam
d)
Distance between
sender (WS) and
receiver (WE) is too large
Test input (Test) is not con‐
nected properly

Measures
None
1. None
2. Adjustment of the configura‐
tion
3. Check electrical connections
a)
Check alignment
b)
Cleaning of the optical
surfaces.
c)
Avoid contamination in
the air as far as possible
d)
Check sensing range
Check connection of the test
input. When using female cable
connectors with LED indicators,
make sure the test input is
assigned correspondingly.
