RCS has been applied to many large-scale intelligent control systems since 1970s. A development methodology, reusable software, and supporting architecting tools have been evolved along the way.
RCS Software Library provides code templates, or generic shell, for RCS controller software modules. The library also provides a communication system called Neutral Messaging Language (NML).
RCS based control systems are typically developed using a methodology that entails a scenario based requirement and system structural analysis process and a generic shell based code development process.
