About Installing Historian Data Collectors

When you install collectors, the required binaries are downloaded. In addition, if iFIX/CIMPLICITY are installed on the same machine as the collectors, instances of the following collectors are created:
  • The iFIX collector
  • The iFIX Alarms & Events collector
  • The OPC Classic Data Access collector for CIMPLICITY
  • The OPC Classic Alarms and Events collector for CIMPLICITY

If an iFIX collector instance created in version 9.0 exists, after you upgrade collectors, another instance of the iFIX collector is created. Because of this, the Remote Collector Manager (RCM) will not work correctly. Therefore, if you want to use RCM, you must delete one of the instances. If needed, you can manually create another instance of the iFIX collector using Configuration Hub or the RemoteCollectorConfigurator utility. This is applicable to the iFIX Alarms and Events collector as well.

Note: If you want to upgrade collectors earlier than version 7.1, additional registries that you create manually are deleted. Therefore, we recommend that you back them up, uninstall the collectors, and then install the latest version.
