10 Troubleshooting for IO-Link Systems
Replacement Method for IO-Link Devices
l Procedure for Backing Up the Parameters from the IO-Link Devices to the
IO-Link Master Unit
First, use the backup functions of the IO-Link device parameter settings to back up the parameters
from the IO-Link devices to the IO-Link Master Unit. The procedure is given below.
1
Use the IO-Link Master Unit Configuration Tool to enable backup with the Backup Setting of
the ports in the IO-Link Master Unit that is connected to the IO-Link devices for which parame-
ters are to be backed up. Disable restoration with the Restoration Setting.
2
Set the parameters in the IO-Link devices. Use the CX-ConfiguratorFDT or hardware on the
IO-Link devices to make the settings.
3
Adjust the devices, and change the parameter settings of the IO-Link devices.
4
Use the start of IO-Link communications or communications instructions to the IO-Link devices
to backup the parameters of the IO-Link devices in the IO-Link Master Unit.
5
Use the IO-Link Master Unit Configuration Tool to enable backup and enable restoration of the
parameters in the IO-Link Master Unit.
6
Operate the devices.
l Procedure to Replace IO-Link Devices and Restore Parameter Settings
Next, after you use the following procedure to replace the IO-Link devices, restore the parameter
settings to the IO-Link devices that were backed up in the IO-Link Master Unit.
1
Turn OFF the I/O power supply to the IO-Link Master Unit.
2
Replace IO-Link devices when they fail.
3
Turn ON the I/O power supply to the IO-Link Master Unit.
4
IO-Link communications are started. The restoration operation is executed automatically.
For details on backup and restoration for IO-Link devices, refer to 7-6 Backup and Restoration of
Parameter Settings in IO-Link Devices on page 7-16.
Precautions for Correct Use
After replacing an IO-Link device, check the following.
• The IO-Link device must be the correct model.
• The device must be mounted at the correct position on the terminal block.
• The IO-Link device must be set correctly and operate correctly.
