PI Interfaces are the first layer of a PI System infrastructure and provide a standard mechanism for collecting data for storage in a PI System. With over 30 years’ experience in collecting data from disparate data sources, and hundreds of interfaces to choose from, OSIsoft PI Interfaces are the foundation of a real-time data infrastructure.

The first challenge in establishing a real-time data infrastructure is to collect the data. The data sources may be disparate and originate from multiple vendors’ devices creating islands of data. These islands of data may include a blend of the latest standard protocols along with older or even retired devices. This data, while related, is not easily analyzed. These data sources may only provide a current value, or minimal historical information making it difficult to understand how your processes change over time.

PI Interfaces connect data sources to a PI System to enable real-time access to historical and current data. Over 400 different PI interfaces are supported connecting PI systems to disparate data sources. Some interfaces enable history recovery, some simply access the history stored in third-party historians. These data sources are seamlessly interwoven into the PI System, independent of source, protocol or vendor. Standard features of PI interfaces include buffering to multiple PI servers, intelligent data reduction (Exception Testing), single tag definition (tags configured on a PI server are synchronized to interface) as well as point by point security. Redundancy and auto point creation are also available on many interfaces.

  Product Function  
  PI Manual Logger Helps your users fully leverage your valuable manually input data. PI Manual Logger enables users to easily and securely collect manual data such as operator rounds, plant surveillance, field inspections, and lab results with a variety of devices including handheld devices, table computers, and PCs. Once collected, this data can be reviewed, approved, and uploaded (wired or wirelessly) to the PI Sever where it can be leveraged by decision makers to make timely and informed decisions. With PI Manual Logger and the PI System, users have a complete operational picture as all data including manually input data, automatically collected data, calculations, etc., is seamlessly presented. Datasheet  
  PI to PI Interface Allows the transferral of PI data between two PI Servers  
  PI COM Connectors Establish connectivity between the PI server and other enterprise systems such as relational databases or other data historians.  
  PI OPC Clients Allows the PI System to access plant floor process data under the OPC standard.
