OPC Server Configuration Unchanged. No New Sources detected with Default support Error When Adding New Devices in PME

Published date: 04 December 2019

 
Issue
After adding a device into PME and selecting update OPC Server the user is met with "OPC Server Configuration unchanged. No New Sources detected with default support."

 



 

Product Line
Power Monitoring Expert 8.X, 7.2.X

Environment
OPC Servers

Cause
The issue is caused because the device that is being added is using a custom driver. The OPC update server option is only for default native drivers. 

Resolution
To resolve the issue, you must open the custom driver in the MDI (Modbus Device Importer) and follow the steps below
  1. Expand the Manager tree
  2. Right click on the module folder you wish to expose to OPC and then click on "OPC..."
  3. Select the measurements and then Click on file
  4. Under file select export.
  5. After the export go back to Management Console and click on the "Update OPC Server" again under tools




 

This time the "Update OPC Server" option will discover the device's measurements that were previously not exposed.
