Sunderam %B Communicating Process Architectures 2002 %X We strive to allow a control system designer the power of designing control computer code concurrently and generating it efficiently, in spite of her or his lack of skills in software engineering. This is important for many reasons. Nowdays, it is impossible to separate control engineering from software engineering. There is no way of implementing control strategies other than to transform them into computer code for the chosen processing target. Usually, there are not so many general\-purpose programmers available in control engineering research teams in companies and universities. In these cases, software development techniques suffer from insufficient knowledge in disciplines of software modelling, concurrency, reusability and testing. This paper develops a case study whose solution is based upon the CSP principles supported by the Communicating Threads libraries developed at Twente and argues why the techniques are accessible to non\-computing\-specialist control engineers.
