The guidance provided in this document, validated in collaboration with ABB and Forescout, provides best practices for preparation and deployment of the ABB ZEE600 platform and the Forescout Platform's eyeInspect within an electrical substation. By leveraging a proven implementation, documented by industry leaders, the path to value is accelerated and the risks are reduced. A jointly produced reference architecture exemplifies critical implementation principles that yield a scalable and repeatable foundation for Industry 4.0 initiatives across an energy provider's grid infrastructure. As modern applications drive utility providers to move more compute resources to the enterprise edge or substation, the solution from Dell Technologies leverages the value of an enterprise-grade, industry-certified infrastructure to run applications closer to where the data is being created and where results are most valuable. This joint energy edge reference architecture, developed in collaboration between Dell Technologies, ABB, and Forescout, delivers unprecedented stability, security, scalability, and repeatability for every substation initiative.
