PI ACE

PI ACE allows users to write, with minimal effort, simple or complex equations, which are reusable for similar data sets.

Features

  • PI ACE provides a managed interface to PI data within the Microsoft Visual Studio environment for application development;
  • Schedule and manage the execution plan for every ACE application;
  • Write a single generic equation and apply it to hundreds, or thousands of contexts;
  • Solve complex data integration problems with an extensible programming environment;
  • Determine and define optimal scheduling for every equation and context.

Benefits

  • Unlimited potential. The PI ACE environment works with any of the Visual Basic programming environments, allowing total flexibility in application creation.
  • Flexible scheduling. Schedule applications via several different options choseable for each individual context. Apply conditions by time, events (simple or complex) or nature.
  • Management made simple. The PI ACE Manager provides a one stop environment for starting or stopping calculations. New contexts or scheduling settings are also available.
  • Fault Tolerant by design.
  • Extensible. Work in the Visual Basic environment to easily expose data to external applications or Web Services.

      Example of Product Implementation

Business Challenge

A large, integrated refinery has approximately 2,500 flow sensors in a single facility. These sensors include a variety of manufacturers and instrumentation vintages. The company needed a way to calibrate every sensor to compensate for changes across this facility.

Implementation

The company installed a PI ACE server to handle the complex calculation associated with this meter compensation issue. A simple asset model was created to reflect the instrument type, maintenance cycles and associated characteristics of each meter. Several engineers coordinated the efforts of creating a single, multi-function compensation algorithm to satisfy their requirements.

Customer Result/Benefit

The company saw immediate results. Roll-up calculations involving redundant meters began to match, and mass-balance calculations began to make sense for the first time in the refineries’ history. They were finally able to believe the results of their work with confidence.
