Easy Replacement of IO-Link Devices
For OMRON's IO-Link Master Units, you can back up parameter settings of the IO-Link devices in the
IO-Link Master Unit.
When you replace IO-Link devices, you can automatically restore the backup parameters in the new
IO-Link devices.
This eliminates the need for software tools when replacing IO-Link devices.
Easy Isolation of Error Locations from the Controller
Before, it was not possible to determine based on ON/OFF signals alone whether signals from sen-
sors or actuators that remained OFF indicated an OFF status or an error.
With IO-Link devices, sensors and other devices can report errors to the master.
This lets you easily detect sensor errors from the controller.
Checking the Quality of IO-Link Communications
OMRON's IO-Link Master Units record the total number of lost frames in cyclic communications. You
can use this value to check the status of IO-Link communications.
