Troubleshooting the Cygnet collector

The CygNet Data Collector generates logs during initialization, configuration, and general operation. These can be found in the general logging folder C:\Proficy Historian Data\LogFiles.

Troubleshooting Tips

Troubleshoot the collector using one or more of the following:

  • Examining the log files for information.
  • Examining the Windows Event Viewer for error/warnings.
  • Be sure to run the CygNet Server before the CygNet Data Collector starts up.
  • Be sure CygNet ODBC Client Tools are installed.

Additional log information can be gathered by using the Cygnet Debug Mode described above for debugging the CygNet to Collector interface.

To turn on debug mode for the Collector:

  • From the Start menu, select Run and enter Regedit.
  • Open the following key folder: HKEY_LOCAL_MACHINE\SOFTWARE\GE Digital\iHistorian\Services\CygnetCollector\<entry>
  • Double-click DebugMode DWORD .
  • Set Base as Decimal.
  • In the Value data field, type 255.
  • Select OK.
  • Restart the Cygnet collector service for the Historian debug mode to take effect.
  • Close the Registry Editor and open the Proficy OPC Classic HDA server trace log file.
    Note: Do not turn on both Cygnet Debug Mode and DebugMode at the same time!

The following error is reported by the collector if the Cygnet 64 Bit APIs are not installed:

Error Setting Cygnet GlobalFunctions object: 'Class not registered' Follow the step below to manually install the CxScript64.dll required by Cygnet collector: regsvr32 "C:\...\8.1.2 Install\CygNet 812\Support64\CxScript64.dll"
Note: Do not turn on CygNet Debug Mode or the DebugMode key for an extended period, 10 minutes should be more than sufficient. Leaving it on will create very large log files and that could use up a great deal of disk space.
