Handling an IO-Link I/O Hub to Replace
If the IO-Link I/O Hub failed, the Hub cannot exchange data with connected external devices, so it af-
fects control of devices.
Restore your system immediately.
To restore your system as soon as possible, it is recommended to prepare a spare.
Considerations for Replacing an IO-Link I/O Hub
When you find a fault during inspection and replace the device, keep in mind the following:
• After replacement, check that there are no problems with the new device.
• When you return a faulty device for repair, send the device to your OMRON representative with a
note describing your problem in as much detail as possible.
• For poor contact, take a clean cotton cloth, soak the cloth in industrial alcohol, and carefully wipe the
contacts.

Replacing an IO-Link I/O Hub
This section describes replacement procedure on the assumption that the following conditions are
met:
• The pre-replacement setting parameters for the IO-Link I/O Hub are already backed up to the IO-
Link Master Unit.
• The conditions for the IO-Link Master Unit to automatically perform restoration when IO-Link com-
munications start are already met.
Refer to the
NXR-series IO-Link Master Unit for EtherNet/IP User’s Manual (Cat. No. W619)
for details
on how to back up or restore the IO-Link device settings to the IO-Link Master Unit. The replacement
procedure is as follows:
1
Turn OFF the Unit/input power supply and output power supply to the connected IO-Link Mas-
ter Unit.
The Unit/input power supply and output power supply to the IO-Link I/O Hub are turned OFF.
2
Replace the IO-Link I/O Hub.
3
Turn ON the Unit/input power supply and output power supply to the connected IO-Link Master
Unit.
The Unit/input power supply and output power supply to the IO-Link I/O Hub are turned ON.
IO-Link communications with the connected IO-Link Master Unit is started.
At this time, parameter settings of the IO-Link I/O Hub that are backed up to the connected IO-
Link Master Unit will be automatically restored to the IO-Link I/O Hub.
