Abstract: | This paper presents a new conception for a distributed task-oriented real-time operating system comprising a compiler, an operating system kernel and communication packages. The system TOROS supplies the tools for a uniform programming of complex process control applications on heterogenous hardware including workstation, PC, programmable controller and microcontroller. The whole control task is split into a set of small modules. These modules are uniquely programmed by defining a state machine and using guarded commands. They are connected logically through calls to tasks provided by other modules. The specification of the modules is done in an hardware independent language. At compile time the modules are distributed to specified target computers. The system automatically translates each module into the particular code and realizes the communication between the modules either on the same computer or through the links. |
