Figure 16 - Major and Minor Fault Information and Data Storage Match Status
Table 24 - Fault and Status Information
Parameter Description Recommended Action
Major Fault Indicates whether a major fault is present on the device. Complete the following:
• Check the device-level IO-Link event log.
• Check the device status in the Parameters view.
• Follow the instructions in the documentation for your device to troubleshoot
the fault.
Minor Fault Indicates whether a minor fault is present on the device.
Data Storage Match
Indicates whether the Data Storage copy in the IO-Link master
module is synchronized with the IO-Link device.
If the device is attached to an IO-Link (non-Fallback) channel and the device
connection is running but the Data Storage Match parameter shows that it is
not matched, contact your device manufacturer.
If the device is on a Fallback channel, complete the following steps:
• Uninhibit the device and verify that the connection is running.
• Inhibit the device and apply the change.
• Go to the Device Info view and refresh the view until the Data Storage Match
parameter shows that it is matched.
• If the Data Storage Match parameter does not show that it is matched after
some time, contact your device manufacturer.
NOTE: After you uninhibit the device, you cannot see the actual status of the
Data Storage Match parameter in the Device Info view.
