Bit
Meaning
VErrV1 Cx
chy/chz
Overcurrent VAUX1 (pin1) at connector/channel group
VErrV1 Cxchy Overcurrent VAUX1 (pin 1) at connector/channel
VErrV2 Cxchy Overcurrent VAUX2 (pin 2) at connector/channel
DXP diagnostics
ERR_DXPx
Overcurrent at the output (if the DXP channel is used as output)
IO-Link master diagnostics
CFGER
Wrong or missing device
The connected device does not match the channel configuration or there is no
device connected to the channel. This diagnostic message depends on the para-
meterization of the channel.
DSER
Data storage error
Possible causes:
n
Data storage mismatch:
IO-Link device in accordance with IO-Link V1.0 connected.
The data storage buffer contains data of another device.
n
Overflow of the data storage buffer
n
The connected device may be locked for parameter changes or for data stor-
age.
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.
