Connection types for a PI trust

When you configure a PI trust, you need to know the type of connection the trust will be used for.

There are two different Data Archive connection types. Each PI interface is configured to use one of these mechanisms (there are also a few interfaces that use both.) The two mechanisms are:

• PI API connection: Most PI interfaces use the PI API to connect to Data Archive.

• PI SDK connection: Most client applications use PI SDK to connect to Data Archive.

The PI API and PI SDK connections both support Windows authentication, which is the most secure authentication method available for the Data Archive server. We recommend that you always use Windows authentication when possible.

If you are not sure which connection type an interface uses, then consult the documentation for that interface.
