In this era of intense liking to automation in almost all time-critical fields, real-time systems have got widespread utilization in industrial, commercial, medical, space and military applications. Modeldriven development of real-time systems has been a task requiring great effort because of the system complexities arising from dealing with quite a huge number of input and output streams within an acute time frame. Complexity exists both in the modeling task as well as in transforming the models into programming language code. Most real-time systems are embedded systems and because of the memory and execution time constraints, they use procedural programming language like C for their platform environment. On the other hand the MDA, an OMG standard Model Driven Development approach, uses an MOF compliant language like UML for the modeling task and the transformation between UML and C is not straight-forward. In this paper we present how the MDA approach can be applied to the development of real-time systems. UML 2.0 is used for modeling and C is used as the target programming language.

Nowadays Unified Modeling Language (UML) has found widespread use in software development of commercial IT systems. But the application in industrial automation is still rare. The domain of process automation involves special requirements on software development. Important requirements on the notation used for software specification arise from the real-time characteristics of industrial automation systems. In order to consider these requirements in software design to avoid a hard clash in development between design and implementation the UML notation has to be used in a specific manner. UML for Process Automation (UML-PA) simplifies system and software development for distributed real-time systems. This paper presents adoptions of UML regarding real-time specific modeling elements.
