Converged Plantwide Ethernet (CPwE) is a collection of architected, tested, and validated designs. The testing and validation follow the Cisco Validated Design (CVD) and Cisco Reference Design (CRD) methodologies. The content of CPwE, which is relevant to both operational technology (OT) and informational technology (IT) disciplines, consists of documented architectures, best practices, guidance, and configuration settings to help industrial operations and OEMs achieve the design and deployment of a scalable, reliable, secure, and future-ready plant-wide or site-wide industrial network infrastructure. CPwE can also help industrial operations and OEMs achieve cost reduction benefits using proven designs that can facilitate quicker deployment while helping to minimize risk in deploying new technology. CPwE is brought to market through a CPwE ecosystem consisting of Cisco, Panduit, and Rockwell Automation emergent from the strategic alliance between Cisco Systems and Rockwell Automation.
Resilient plant-wide or site-wide network architectures play a pivotal role in helping to confirm overall plant/site uptime and productivity. Industrial Automation and Control System (IACS) application requirements such as availability and performance drive the choice of resiliency technology. A scalable, holistic, and reliable plant-wide or site-wide network architecture is composed of multiple technologies (logical and physical) deployed at different levels within plant-wide or site-wide architectures. When selecting resiliency technology, various IACS application factors should be evaluated, including physical layout of IACS devices (geographic dispersion), recovery time performance, uplink media type, tolerance to data latency and jitter and future-ready requirements.
Physical Infrastructure for the Converged Plantwide Ethernet Architecture, which is documented in this Application Guide, outlines several physical layer use cases for designing and deploying reliable OEM, plant-wide or site-wide architectures for Industrial Automation and Control System (IACS) applications.
