TBPN-L1-FDIO1-2IOL - Standard IO-Link
Master/device diagnostics
PDINV Process input data invalid
The IO-Link master or the IO-Link device
report invalid process input data.
The connected device is not in status "oper-
ate", which means, it is not ready for operation.
Possible sources:
The connected device does not match the
configured one, additional diagnostic mes
-
sage “Wrong or missing device”.
Certain IO-Link devices send a "process input
data invalid"-diagnosis if the process value
cannot be measured.
Deactivate the sending of the "process input
data invalid"-diagnosis for the respective port.
To do so, change the parameter "Process
input data invalid" to "no diagnostics gen-
erated", s. page 16.
Device diagnostics
For the exact specification of the device diagnostics, please read the device documentation of the device
manufacturer.
HWER Hardware error
General hardware error or device malfunction.
EVT2 Out-of-specification events
An Out-of-Specification Event in accordance with the IO-Link specification occurred.
EVT1 Maintenance events
A Maintenance Event in accordance with the IO-Link specification occurred, maintenance
necessary.
PRMERR Parameterization error
The connected device reports a parameterization error (loss of parameters, no parameter ini-
tialization, etc.).
OTMP Over-temperature
Temperature diagnostic message at the connected device.
LLVU Lower limit value under-run
The process value lies under the parameterized measurement range or the chosen measure-
ment range has been chosen too high.
ULVE Upper limit value exceeded
The process value exceeds the parameterized measurement range or the chosen measure-
ment range has been chosen too low.
VLOW under voltage
One of the voltages at the connected device is below the defined range.
VHIGH Over-voltage
One of the voltages at the connected device is below the defined range.
OLV Overload
The connected device detected an overload.
GENER Common error
The device sends an error (device status 4, in accordance with IO-Link specification), which is
not clearly specified.
Read out the device event codes in order to be able to specify the error more precisely.
