Troubleshooting the Collector

The OPC UA DA collector generates log files during initialization, configuration, and general operation. By default, you can find them at C:\Proficy Historian Data\LogFiles.

Troubleshooting Tips

If the collector does not connect to the OPC server, or if tags are not displayed:

• Ensure that the certificate is added to Trusted list.
• Ensure that you have provided a valid username and password.
• Restart the collector whenever there is any change made to the configuration using Historian Administrator or in the ClientConfig.ini file.
• Check that secured Connectivity is true and Enable User security is checked to have connection with User Authentication.
• Ensure that the OPC server supports the security policy and the security mode if you see the following error message in the log file: Matching of secure endpoint not available between server and collector.
• Ensure that the RetryInitialConnect and AutomaticReconnect parameters are set to true in the ClientConfig.ini file.
