Page 2 - INDUSTRIAL NETWORKS AND BUSES; lines, but for our purposes they will be grouped into

Industrial Network Track: Multi-Bus Author Jim W. Hammond – Technical Consultant, GarrettCom, Inc. Keywords: Network integration, Ethernet, TCP/IP, field buses, topology Last time I checked it was reasonably easy to get a bus transfer in NYC, but don’t expect that level of ease when doing transfers ...

7-Application 6-Presentation 5-Session 4-Transport 3-Network 2-Data Link 1-Physical OSI MODEL If you’ve never seen the OSI model, avert your eyes from the following diagram. Too late. It’s not possible to read any book on data communications and networking and avoid seeing this conceptual view of a ...

Profibus is supported by Siemens and has a large presence in Europe with three protocol variations. It supports various media and topologies at speeds up to 12Mbit/s. The PROFINET spin-off is discussed later. Foundation Fieldbus is a special case that straddles proprietary and open standards. It use...

SUMMARY The open standard networks support multiple topologies over Ethernet at speeds of 100Mbit/s or better and provide TCP and UDP interfaces. This should make clear the evolution to high speed Ethernet over a variety of topologies. INDUSTRIAL ETHERNET Industrial Ethernet supports the integration...

Page 6 - Integrated Substation Network; NETWORK INTEGRATION

Integrated Substation Network NETWORK INTEGRATION The hard choices of integration include decisions of how to connect to proprietary systems. This will vary from industry to industry. Most legacy systems that continue to perform well are candidates for some form of gateway interface unless local man...

• Integration: The ability to manage a large network from central or distributed locations, economies of scale, network visibility, and other factors without time-consuming testing of incompatible interfaces can provide huge benefits. • VLAN support: The ability to define virtual networks for managi...

Page 8 - USING ETHERNET TO NETWORK; TOPOLOGY AND REDUNDANCY

USING ETHERNET TO NETWORK There are many ways Ethernet components and standards can be employed to provide redundancy, robustness, security, and flexibility of design for many industrial networks. As has already been mentioned, Ethernet is also the best integration strategy available to network plan...

Distributed with permission of author by ISA 2006 Presented at ISA EXPO 2006 SUMMARY ON BUS STRATEGIES There are two reasons to maintain proprietary buses: legacy systems that are still providing satisfactory service, and highly tuned and specific applications. However, in a world where costs, high ...
