Learn about mappings and trusts

Use the PI SMT Mappings & Trusts tool to create and edit PI mappings and trusts on the Data Archive server.

Before Data Archive 2016 R2, trusts were typically used to authenticate PI interfaces, while on the Data Archive server, mappings were used to authenticate Windows users via single sign-on. With PI API 2016 for Windows Integrated Security, Windows authentication extends to PI interfaces.

Note: PI API 2016 for Windows Integrated Security extends Windows authentication to API-based client applications. If you choose to install PI API 2016 for Windows Integrated Security, you can use only Windows Integrated Security for authentication. Both trusts and explicit logins will fail.
