7-Application 6-Presentation 5-Session 4-Transport 3-Network 2-Data Link 1-Physical OSI MODEL If you’ve never seen the OSI mode l, avert your eyes from the follo wing diagram . Too late. It’s not possible to read any book on data co mmunications and networking and avoid seeing this conceptual view of a generi c network architecture.
Profibus is supported by Siemens and has a large presence in Europe with thre e protocol variations. It supports various media and topologies at speed s up to 12Mbit/s. The PROFINET spin-off is discussed later. Foundation Fieldbus is a special case that st raddles proprietary and open standards.
SUMMARY The open standard networks support multiple topologi es 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.
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.
• Integration: The ability to manage a large ne twork from central or distributed location s, economies of scale, network visibility, and ot her factors without tim e- consuming testing of incompatible interfaces can provide huge benefits. • VLAN support: The ability to define virtual networks for m anaging traffic and security.
USING ETHERNET TO NETWORK There are many ways Ethernet components and st andards can be employed to provide redundancy, robustness, security, and flexibil ity of design for m any industrial networks. As has already been mentioned, Ethernet is also the be st integration strategy available to network planners and architects.

An important point after buying a device GarrettCom OSI (or even before the purchase) is to read its user manual. We should do this for several simple reasons:
If you have not bought GarrettCom OSI yet, this is a good time to familiarize yourself with the basic data on the product. First of all view first pages of the manual, you can find above. You should find there the most important technical data GarrettCom OSI - thus you can check whether the hardware meets your expectations. When delving into next pages of the user manual, GarrettCom OSI you will learn all the available features of the product, as well as information on its operation. The information that you get GarrettCom OSI will certainly help you make a decision on the purchase.
If you already are a holder of GarrettCom OSI, but have not read the manual yet, you should do it for the reasons described above. You will learn then if you properly used the available features, and whether you have not made any mistakes, which can shorten the lifetime GarrettCom OSI.
However, one of the most important roles played by the user manual is to help in solving problems with GarrettCom OSI. Almost always you will find there Troubleshooting, which are the most frequently occurring failures and malfunctions of the device GarrettCom OSI along with tips on how to solve them. Even if you fail to solve the problem, the manual will show you a further procedure – contact to the customer service center or the nearest service center
