PI Data Archive configuration

PI DataLink can retrieve data from Data Archive 3.4.380 and later. However, PI DataLink must be able to connect to the proper Data Archive server and users must have proper access to points. This might require configuration changes for:

• Firewall database

  The firewall database on each Data Archive computer must be configured to allow access from client computers that run PI DataLink.

• Authentication and authorization

  Those using PI DataLink must be able to authenticate their identity with Data Archive and have access to Data Archive. Assign users the least-privileged access possible, such as read-only permissions. For authentication, AVEVA recommends that you use Open ID Connect Role PI Mappings (available in PI Data Archive version 2023 and later). If Open ID Connect Role PI Mappings are not available, AVEVA recommends using Windows PI Mappings (available in PI Data Archive version 3.4.380 and later). You can also use PI trusts or PI password authentication. AVEVA does not recommend PI password authentication as that method is less secure.

• Point definitions

  Points must be defined to give authorized users read access, and write access, if necessary.
