Troubleshooting the Collector

The OPC Classic HDA collector generates log files during initialization, configuration, and general operation. You can find them in the following folder by default: C:\Proficy Historian Data\LogFiles.

• Be sure to run the OPC Classic HDA server before the OPC Classic HDA collector starts up.
• If the OPC Classic HDA collector does not start automatically, refer to the Historian log file to view log entries to determine the problem.
• Enable the CreateOfflineArchives flag in the Destination Historian as the OPC Classic HDA collector pushes the old data.
