PI Server 2018 provides many enhancements and bug fixes to PI Data Archive and PI Asset Framework focused on improving performance and usability.

The major new features being introduced in this release include:


  • Introduction of a single combined PI Server setup kit that includes PI Data Archive, PI Asset Framework with Asset Analytics and Notifications, PI Web API, PI System Directory and all dependent components.  Users can choose the desired components to install in a new installation.

Data Archive

  • Upon initial connection, rather than all clients connecting to the primary member of a Data Archive collective client connections will now be automatically distributed to all available collective members.
    • After an HA failover, failback switches the client connection back to the original member.
    • This feature is only available for AF SDK based applications. To enable this feature on a client computer, please consult the relevant release note.

  • Support for new Element traits including Health Status and Health Score.
  • Bi-linear interpolation of AF tables.

  • Native integration with MATLAB Production Server.
