Diagnostic bit Meaning
NO_DS The parameterized port mode (see Parameters (page 17)) does not support data
storage.
Remedy:
– Change the parameterization of the port.
DS_F Error in the data storage, synchronization not possible
Possible causes:
– Connected device does not support data storage
– Overflow of the data storage buffer
Remedy:
– Connect a device that supports data storage.
– Clear the data storage buffer.
– Deactivate the data storage.
TCYC The device does not support the cycle time parameterized in the master.
Remedy:
– Increase the cycle time set in the master
NO_SIO The device does not support the standard DI mode (see parameter Mode (page
17)).
Remedy:
– Select the IO-Link mode for this port.
NO_PD No process data available The connected device is not ready for operation.
Remedy:
– Checking the configuration
PDI_E The connected device reports invalid process data in accordance with IO-Link
specificati
on V1.0.
PDI_H The connected device reports invalid process data in accordance with IO-Link
specificati
on V1.1.
MD Missing device: No IO-Link device detected
Remedy:
– Check the IO-Link cable.
– Change the device.
WD Wrong device detected: one or more parameters of the connected device (Ven-
dor ID, Device ID, serial number) does not
/do not match the data which are stored
in the master for this device.
Remedy:
– Change the device.
– Adapt the master parameterization (see parameter Mode (page 17))
