Should Something Go Wrong

When deployed to the HCC2, any tags that are being written to will appear in the Live Data page in the HCC2's Unity interface. If expected tags are not present, then look in the System Logs for errors. Use the filter in the columns to locate the application's log entries.

Typical errors include :

  • The wrong HOST or PORT, resulting in connection failures
  • Data format errors, resulting in casting or convert type errors
