These whitepapers and articles are things that I have written that I think pertain to data acquisition and process control. I believe that it is information that might prove valuable to others and I will try to explain what each of the following demonstrates as part of it's bullet listing.
When you start the process, you generally know what it is that you want to do and how you want to do it. You will usually have some goals that look reasonable but are unrealizable because of time or cost constraints. During the implementation, you will undoubtedly realize that the system will be better if you do something differently. Once the system is running, you will recognize that the system itself has a natural rhythm or "sweet spot" that will cause it to run better.
Adapting to these changes in understanding and requirements will allow you to build the best system possible within your budget and time constraints.
Any system that has the potential to harm others should have a safety interlock system. Some systems are bound by law and by contract to include interlocks. Many home brew systems don't incorporate interlocks although they should. There are "due diligence" liabilities that you should consider, no matter how tempting it is to cut corners.
This is a particularly important topic and this paper is just a starting point that I hope to expand on more in the future.
"TCP/IP communication with embedded processors, using text commands, is fast and reliable. Best of all, it doesn't strain a host PC's resources. Cass describes how to implement a TCP/IP socket server on a Rabbit Semiconductor RCM2200 microprocessor."
This article documented the predecessor of the Client/Server code. The article was published with the blessings of ATK, who I worked for at the time, and it moved this information safely into public domain. This type of Client/Server communication provided a foundation for almost all of the subsequent systems that I worked on, so it has important historical value to me. I appreciate ATK's willingness to share this paradigm with everyone else. Thanks ATK.
