Continuing from Part 1 where we introduced the fit-for-purpose layered approach to analytics, in this session we will review the built-in data engineering capabilities in the PI System.

Raw time-series sensor data is often transformed to another metric – say, convert flow rates to standard volumes and tank levels, derive statistical aggregates such as hourly/daily averages, hourly/daily totals, convert using first principles physics/math equations, and others. Also, datasets can be filtered for process/equipment events - turbine trip, compressor failure, pharmaceutical batch, catalyst poisoning, heat-exchanger fouling etc. And, you can incorporate material flow related latencies in the dataset, for example, the 14-hour lag as wood chips are cooked and flows through various process units to be converted to paper or in the metals industry where iron ore is mined and goes through a number of steps to be converted to ingots, thus allowing you to capture SME (subject-matter-expertise) knowledge.

With illustrative use cases, we will review how such preprocessing for industrial time-series data is critical for data visualization and for advanced analytics, including machine learning with R/Python libraries or cloud platforms such as Microsoft Azure, Amazon AWS and Google GCP.
