Model Driven Development (MDD) has been proved as a quite successful paradigm in general-purpose computing and is currently exploited in the embedded systems domain. On the other hand, the majority of industrial automation systems is developed based on the IEC 61131 standard. This standard defines a model and a set of programming languages for the development of industrial automation software and it is supported by the majority of the commercial tools in this domain. This work proposes an MDD process to increase the productivity and reliability of the development process of industrial automation systems. Piping and instrumentation diagrams are considered as source of requirements for processcontrol engineering and SysML is used to reduce the gap between these diagrams and the 61131 based design specs of the control system. The foundation for a SysML profile to facilitate the exploitation of SysML in this domain is described. This profile will allow the developer to work in higher layers of abstraction than the one supported by IEC 61131 and effectively move from requirement specifications into the implementation model of the system.

This paper presents a UML-based engineering environment for the design and implementation of hybrid systems in forming technology. The discrete superordinate steps of forming technology are programmed as an activity diagram (UML). Some process steps include control loops which are modeled in Simulink. The control loops are automatically generated into Continuous Function Chart (CFC) in Programmable Logic controller (PLC). The paper describes how the controllers can be distributed with different task cycle times and how the performance of these controllers can be ensured during runtime. In the process, the activity diagram is compared with the standard IEC 61499 considering the aspects usability and execution/implementation.
