Advances in PI System Streaming Analytics and Other External Calculation Engines Stephen Kwan, OSIsoft Product Manager Tim Choo, MATLAB Production Server Product Manager 1
Goals and Objectives Use PI System as the data infrastructure Enable users to execute advanced streaming calculations Execution based on new events into the PI System or by clock Encourage reuse of existing domain expertise Support different personas Engineers, designers, users, etc. Retain ease of use, feature set and existing workflow 2
Advanced Streaming Calculations Asset Analytics released in 2014 PE replacement Leverages AF and PI System Configuration experience Robust engine with scheduler Widely used, but users want more Advanced calculations More flexibility Retain ease of use 3
Integration with 3 rd Party Calc Engines Calc engines for computational mathematics exist Take advantage of existing applications MATLAB is the first 3 rd party integration with Asset Analytics MATLAB is used by millions of engineers and scientists Many PI users have existing MATLAB code Collaboration between MathWorks and OSIsoft Mutual feedback for improvements Faster time to market 4
Personas: Streaming vs. Adhoc Adhoc investigation and analytics development Online, scheduled, streaming analytics 5
Integration with MATLAB Production Server Analytics Development HTTP/HTTPS MATLAB Production Server MATLAB Compiler SDK MATLAB Package Code / test Requirements PI Asset Framework 2018 MATLAB Production Server R2018a MATLAB, MATLAB Compiler and MATLAB Compiler SDK R2018a 6

Predictive Maintenance Toolbox New Design and test condition monitoring and predictive maintenance algorithms Feature extraction for designing condition indicators Machine learning and time-series models for remaining useful life (RUL) estimation 12
Analyzing HVAC data with MATLAB follows four basic steps 13
1 Access and Explore Data 2 Preprocess Data Its easy to explore, clean, and preprocess data with MATLAB 14
3 Develop Predictive Models Its easy to build a predictive model in MATLAB Use apps to help understand methods and workflows 15
3 Develop Predictive Models Its easy to try different models on the same data Neural Networks Time series models (ARIMA, GARCH,..) 16
3 Develop Predictive Models MATLAB s Regression Learner App lets you train with multiple algorithms in parallel 17
4 Integrate with Production Systems Deploy your predictive model as a reliable and scalable service with MATLAB Production Server MATLAB Compiler SDK Analytics Development MATLAB Deploy Package Code / test Access Integrate Data sources MATLAB Production Server Worker processes Request Broker Enterprise Application < > Mobile / Web Application Scale and secure 3 rd party dashboard 18
4 Integrate with Production Systems The Deployment Tool with Compiler SDK makes it easy to package and deploy your predictive model 19
4 Integrate with Production Systems MATLAB Production Server operationalizes your predictive model as a scalable and reliable service Predictive Model MATLAB Production Server AF with Asset Analytics Worker processes Request Broker Call analytic functions using REST API 20
Enhanced Data handling Complex Data Types Support MATLAB data needs Asset Analytics mostly handled single values only Introduce support for multiple values as arrays in analyses Configuration UI improvements Enhance existing functions for single values and arrays PI data infrastructure = first class citizen 21
User Experience Retain existing user experience External codes are treated as Expression functions Authoring, testing, preview, scheduling, backfill, recalculation, etc. remain the same 22
Data Retrieval and Array Operation Functions 23
Example Use Cases I Of need these the data last values, last 50 for archive 50 the I want archived last values, day to apply values in I 30 only a second transform want increments ones to > them 185
