Proceedings of the 13th Realtime Linux Workshop
Most real-time applications in context to automatic control and data acquisition do require user interfaces to change parameters or to extract data at runtime. Especially in prototyping control processes, it is common to use CACSD programs such as Matlab or Scicos for code generation. While still being in the prototyping stage the customer demands to start evaluation using a software tool. Very often those customers do not possess the ability to work with CACSD tools or other tools as xRTAILab because of missing licenses or lack of knowledge in linux. To close the gap between the real-time target and data evaluation a remote control framework is introduced. Our approach is to use RTAIXML as a XML-RPC server. It is running on the rt-system and has the ability to connect to the CACSD generated code. This server instance can be contacted through a platform independent Java framework which allows quick prototyping of simple to use user interfaces without interfering the control system development. It is possible to transfer scopes and to change parameters on running targets. A successful application is shown on the example of a low cost rheometer.
