TOP Server Architecture Gives you Flexibility and Choice We believe one of the prime advantages to our users is a software architecture that enables flexibility, responsiveness, and performance. The drawing below shows the TOP server architecture. There are several key areas that we often point out to our clients. Single engine offers multiple Software Interfaces. Notice carefully that the OPC, FastDDE, Suitelink and AdvanceDDE interfaces to other software are independent of each other. There is no "wrapping" of interfaces going on here. A common analogy we use is to imagine a large department store with many doors -- regardless of which you come in, once you are in the store, everything is available to you. Independence of Hardware Specific Drivers - since each specific PLC or automation device hardware driver is a separate piece that snaps into the TOP server engine, we can revision a driver and not effect others. Furthermore, features can be added to the engine that instantly become available to the over 50 unique drivers available to you. Performance - the drivers are in process DLLs that are multi-threaded and highly optimized for their specific tasks. You will find that when put to the test, the limiting factor will often be the PLC network, not the TOP server driver. Since each software interface in the TOP server operates independent of others without wrapping, they be active simultaneously and the highly responsive multi-threaded core engine Responsiveness - the modular architecture allows us to respond quickly to your needs and add new capabilities very quickly.  Don't be afraid to ask for a quote on engineering for specific features you might need - we get a lot of requests but you will find we are able to do things quickly and economically in many cases. Low Training Costs - because the interface to the user is through the core engine and the only driver specific dialogs get pulled through the driver specific DLL and follow consistent formats, once you know one of the TOP server drivers, you'll feel right at home with the others. We hope that from this picture and paper that you've learned more about why the TOP Server is your best choice for communications integration solutions. Please feel free to send us an email with any questions you may have or call us at 704-849-2773.
