IO-Link Device Configuration Change Notification
If any configuration parameters are changed in an IO-Link device while the connection is
active, the
ConfigChanged
tag is set to 1 in the input data of the device. You
can set the ResetConfigChanged
tag from 0 to 1 in the output data to acknowledge
the configuration change.This feature is only supported when the device supports Data Storage. The notification is
triggered when the Data Storage checksum in the device is changed due to any external
configuration change.
Examples of external change are explicit messaging or local change through the physical
panel/switch on the device. Configuration changes through the Studio 5000 Logix Designer
application or reconfiguration instructions are not considered external changes.
To acknowledge the configuration change, do the following:
- Trigger a rising edge of theResetConfigChangedtag in the output data to clear theConfigChangedtag.
- In the IO-Link device Module Properties → Configuration view, perform Device Correlation Check and select “Use Device Values”.
- Review the new values of all parameters.
- If the new values are appropriate, select Apply to save the values to the project.Otherwise, select Cancel to revert to the original configuration. Then perform Device Correlation Check again and select “Use Project Values” to restore the original configuration to the device.
- Check that theConfigChangedbit has changed to 0 to verify that the configuration change is acknowledged.If the bit is 1, it means that the external configuration change is still in progress. Repeat the steps to acknowledge the configuration change and synchronize the project values and device values of the device configuration.
