The operation is
unstable.
(chattering)
The hysteresis is
small and is
affected by the
fluctuations in the
original pressure,
etc.
Check the set value (hysteresis).
Check the settings
Incorrect wiring/
broken lead wire
(1) Check the power supply wiring.
(2) Check if there is bending stress
applied to any part of the lead wire.
(bending radius, tensile force to the
lead wire)
(1) Check and correct the wiring.
(2) Correct the wiring.
(Reduce the tensile force or
increase the bending radius.)
Product failure
Replace the product

-
incorrect wiring
Check the connection of
the connector.
Correct the cable wiring.
Power supply
error from the
IO-Link master
Check the power supply
voltage from the IO-Link
master.
Supply 18 to 30 VDC to
the IO-Link master.

Communication is
not established.
IO-Link wiring
failure
Check the connection and
cable condition of the
IO-Link cable.
Additionally tighten the
IO-Link cable. (Replace
the cable if it is broken.)

IO-Link master
and product
version are not
matched.
Check the IO-Link version
of the master and device.
Align the master IO-Link
version to the device.

Communication
mode is not
transferred to the
Operation mode.
Check the setting of the
data storage access lock
and data storage backup
level of the master.
Release the data storage
access lock.
Or deactivate the setting of
the data storage backup
level of the master port.
Data is swapped
by byte.
-
Program data
assignment is
incorrect.
Check that the Endian
type on the master upper
level communication
transmission format is Big
Endian type or Little
Endian type.
Assign the program data
based on the Endian type
of the transmission format
of the master upper level
communication.
Or set to the master byte
swap setting.
(Refer to page
Endian type of the upper
level communication)
1: When the product is connected to the IO-Link master with version other than "V1.1", an error will be generated.
