Bit Meaning
PPE Port parameterization
The port parameters are inconsistent. The device parameterization via GSD is
active, but not working.
Possible causes:
n The IO-Link master did not receive GSDML-parameters for a connected
device. The connected device was not parameterized by a PROFINET PLC via
GSDML.
n The port is in operation mode "IO-Link without validation" or "DI". These
modes do not allow parameterization via GSDL file.
n Data storage mode is active. The parameter is not set to "deactivated, clear".
A device parameterization via GSDML is not possible with activated data stor-
age.
n Vendor or Device ID are "0". The connected device can not be identified and is
thus not parameterizable.
IO-Link master/device diagnostics
PDINV Evaluating Process Input Data
The IO-Link master or the IO-Link device report invalid process input data. The
connected device is not in status "operate", which means, it is not ready for op-
eration.
Possible sources:
n The connected device does not match the configured one, additional dia-
gnostic message Wrong or missing device.
n Diagnostic message Process input data invalid because the process value
can not be measured (depends on the IO-Link device).
IO-Link device diagnostics
The IO-Link device diagnostics depend on the IO-Link device used. For more de-
tailed information on the diagnoses, please refer to the documentation for the
IO-Link device.
EVT1 Maintenance events
A Maintenance event in accordance with the IO-Link specification occurred,
maintenance necessary.
EVT2 Out-of-specification events
An Out-of-specification event in accordance with the IO-Link specification oc-
curred.
GENERR Common error
The device sends an error (device status 4, in accordance with IO-Link specifica-
tion), which is not clearly specified. Read out the device Event Codes in order to
be able to specify the error more precisely.
HWER Hardware error
General hardware error or device malfunction.
LLVU Lower limit value underrun
The process value lies under the parameterized measurement range or the
chosen measurement range has been chosen too high.
OLV Overload
The connected device detected an overload.
OTMP Overtemperature
A temperature diagnosis is available on the connected device.
PRMERR Parameterization error
The connected device reports a parameterization error (loss of parameters, no
parameter initialization, etc.).
