PI OPC HDA Server
Current Version: 2016 (1.2.7.5)

PI OPC HDA Server Overview

OSIsoft has server implementations of two OPC Standards: theĀ OPC Data Access (DA) standard and the OPC Historical Data Access (HDA) standard. This Overview page is about the PI OPC HDA Server which implements the Historical Data Access standard. (For information on the PI OPC DA Server, read the PI OPC DA Server Overview.)

PI OPC HDA Server will allow any industry-standard HDA client application to read data from PI, insert new data into PI, or delete data from PI. The server allows access both to PI Data Archive tags and to the PI Module Database (PI MDB) modules, aliases, and properties. Note that not all interfaces and methods are implemented for PI MDB objects since not all of the OPC interfaces and methods make sense in this context.
 
PI OPC HDA Server can be installed on the same system as PI Data Archive, or it can be installed on a separate system. It can communicate with any number of PI Data Archives.
