Troubleshooting the OPC Classic HDA Collector

The OPC Classic HDA collector generates log files during initialization, configuration, and general operation. By default, they are available in the following folder: C:\Proficy Historian Data\LogFiles.

If you encounter issues with the collector:

• Verify that the OPC Classic HDA server is running before the OPC Classic HDA collector starts up.
• If the OPC Classic HDA collector does not start automatically, refer to the log file to identify the issue.
• Enable the CreateOfflineArchives option in the destination Historian as the OPC Classic HDA collector sends the old data.
