In Part 1 of this technical keynote, we cover PI System's role as the backbone of an open data infrastructure in your digital transformation journey. In asset intensive industries (oil & gas, power generation, renewables, metals & mining, pharma, cement etc.), OT - operations technology - data includes SCADA, IoT, machine condition, MES and any other meta data that adds context and enriches instrument/sensor measurements. With a layered approach to fit-for-purpose analytics, the PI System enables your digital transformation to evolve through descriptive/diagnostic/predictive/prescriptive operation or reactive/preventive/predictive maintenance, and others. We will use illustrative customer examples and demos to walk you through the scenarios. The talk will also include new OSIsoft technologies in the roadmap - edge data store (EDS) and OSIsoft Cloud Services (OCS).
