About a month ago I wrote a blog on LabVIEW application architectures, but I wanted to supplement that with links to more advanced resources that are specific to certain applications and offer a more holistic insight into the task of architecting your LabVIEW application.
A Primer for Machine Control - If you're building a large system for machine control using CompactRIO and aren't sure where to start, this should help. It includes example applications and insights into networking and how to manage multiple tasks.
TestStand Architecture Series - as automated test systems are becoming larger and more complex, it's becoming increasingly important to architect your code to ensure scalability, quality and re-usability. This series of content was written largely by NI Alliance Partners who have extensive experience with applications of this nature.
Architecting applicatioins in any language is one of the biggest challenges any software programmer faces. Compared to the task of designing code, the task of actually developing it is often the easiest par. Without carteful consideration, many programmers get the 're-factor' twinge about half-way into the development process. If any of this sounds familiar, spend some time looking through these resources to get some insight into paradigms that might help you and your application succeed.
