For Part 2, see  The-7-steps-in-US-DoE-eGuide-for-ISO-50001-to-implement-an-energy-management-system-how-can-pi-system-products-meet-some-of-these-requirements



The PI System meets several of the EnMS requirements via a suite of integrated modules that are categorized under: Collect, Historize, Find, Analyze, Deliver, and Visualize.

  • Collect includes PI Interfaces that collect data from a multitude of data sources.
  • Historize includes PI Server that works with the PI Interfaces to provide the real-time data collection, archiving, and distribution services. The PI Server brings all the relevant data from disparate sources, such as enterprise systems, databases, and operational data sources into a single system, secures it so appropriate access is given to individuals based on their roles, and delivers it to users and applications at all levels of the enterprise.
  • Find includes PI Asset Framework (PI AF) and PI Event Frames (PI EF). PI AF provides for a configurable meta-data layer that can host multiple data models - a process flow, i.e. connectivity model, an equipment component model, a transaction object model, and others.  PI EF provides the infrastructure and a configurable model for storing data by manufacturing events.
  • PI AF and PI EF work together to quickly find the appropriate data in the correct context and inter-relate data and events to profile your energy situation.
  • Analyze PI Analytics provide real-time analytics and enables you to analyze and aggregate real-time and historical data and events into user-defined actionable information or key performance indicators (KPIs).
  • Deliver PI Data Access and PI Notifications provide the functionality to deliver data when, where and how it is needed. PI Data Access supports a number of industry standards such as Web Services (SOAP), OLEDB, ODBC, JDBC, OPC, and others. XML based i/o is supported and with appropriate XSL transform files, it can be used for XML messaging based data exchange
  • Visualize includes PI Coresight, PI WebParts, PI DataLink, PI ProcessBook and others to meet the functional requirements with regard to energy analysis, and energy tracking/reporting.

As a follow up to the previous post, the items in red below indicate the steps from the US DoE eGuide where the PI System capabilities can be used.  For several items, one or more PI System products can completely meet a Step’s requirements. However, in other Steps, the requirements are outside the scope of the PI System and you have to use other tools.

Step 1 Getting Started

Step 2 Profile Your Energy Situation

Step 3 Develop Objectives, Targets and Action Plans

Step 4 Reality Check: Stop! Look! Can I Go?

Step 5 Manage Current State and Improvements

Step 6 Check the System

Step 7 Sustain And Improve The System

Do you have an active ISO 50001 or Energy Management project where you are using the PI System stack?  Please share your findings.
