Troubleshooting
If the device does not work as expected, proceed as follows:
Exclude environmental disturbances.
Check the connections of the device for errors.
Check device for parameterization errors.
If the malfunction persists, the device is faulty. In this case, decommission the device and re-
place it with a new device of the same type.

Wrong or missing
device
The connected device does
not match the configured
one (wrong vendor-ID,
device-ID etc.)
Adapt the parameterization of the
IO-Link port (Vendor ID, Device ID,
etc.) at the master.
The parameterization can be done
manually via DTM, the web server or
similar or by teaching the master us-
ing the IO-Link Call (port 0 function,
sub index 67: Teach mode).
Evaluating Process
Input Data
Certain IO-Link devices send a
process input data invalid
diagnosis if the process value
cannot be measured.
Deactivate the sending of the dia-
gnosis for the IO-Link port with the
