Preface

Preface

Converged Plantwide Ethernet (CPwE) is a collection of tested and validated architectures. 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 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 an ecosystem consisting of Cisco, Panduit, and Rockwell Automation emergent from the strategic alliance between Cisco Systems and Rockwell Automation.

Deploying Scalable Time Distribution within a Converged Plantwide Ethernet Architecture CRD (CPwE Time), which is documented in this Design Guide (DG), outlines several use cases for designing and deploying Scalable Time Distribution technology throughout a plant-wide Industrial Automation and Control System (IACS) network infrastructure. CPwE Time highlights the key IACS application requirements, technology, and supporting design considerations to help with the successful design and deployment of these specific use cases within the CPwE framework. CPwE Time was architected, tested, and verified by Cisco Systems and Rockwell Automation with assistance by Panduit.
