An Internal Error Has Occurred: The Device Identity Data Is Not Valid for This I/O Plugin

Issue Details

When working with a CompactRIO (cRIO-9057) and a 9145 EtherCAT chassis or any other 3rd party EtherCAT slave device, after renaming a module or adding a new one the following error occurs during deployment.

Error Code: 0xFFFEFE26   An internal error has occurred: The device identity data is not valid for this I/O plugin. 

How can I resolve this error?

Solution

When you deploy the new EtherCAT configuration from LabVIEW project, the new configuration conflicting with the EtherCAT configuration already deployed in the NI Real-Time controller. In order to resolve this error, you need to undeploy the existing EtherCAT configuration first before deploying a new EtherCAT configuration.

1. Open the related LabVIEW project.
2. Right click the EtherCAT Master and select Undeploy. 
   
    
3. After completed the undeploy process, you can deploy the new configuration by clicking Deploy.
   
    

If the above did not resolve the error, you can try the following troubleshooting steps.

• Ensure that the C Series modules and EtherCAT chassis are compatible with your LabVIEW version. Refer to C Series Module and CompactDAQ or CompactRIO Hardware Compatibility with LabVIEW.
• Reset NI MAX Database
  1. Open NI Measurement & Automation Explorer (NI MAX) and reset the database to clear any corrupted device configurations. Reset and Fix the Measurement & Automation Explorer Database File
  2. Restart the cRIO system.
  3. Re-detect and configure your hardware.
  4. Redeploy the project and modules from LabVIEW.
