Industrial Networks Summary

Open networks are in demand Broad availability of products, applications and vendor support for Industrial Automation

Network standards for coexistence and interoperability of industrial automation devices

Convergence of network technologies Reduce the number of disparate networks in an operation and create seamless

information sharing throughout the plant-wide / site-wide architecture

Use of common network design, deployment and troubleshooting tools across the plant-

wide / site-wide architecture; avoid special tools for each application

Better asset utilization to support lean initiatives Common network infrastructure assets, while accounting for environmental requirements

Reduce training, support, and inventory for different networking technologies

Future-ready – maximizing investments and minimizing risks Support new technologies and features without a network forklift upgrade

Reduce Risk Simplify Design Speed Deployment


A new ‘go-to’ resource for educational, technical and

thought leadership information about industrial

communications
