PI to PI Interface Overview

The PI to PI Interface transfers data from one PI Server (the source server) to another PI Server (the receiving server) via TCP/IP. For each copy of the interface used, several source servers (one for each scan class) may be configured to send data to a single receiving server.

Data is transferred for a list of points defined in the receiving PI server point database, each of which has a source PI server tag name with which it is associated.

Starting with version, the interface supports a failover mechanism that enables the retrieval of data from either of two redundant source servers.
