The more complex automation applications are evolving, the more difficult it is for developers to coordinate and to order the different tasks for safety monitoring and control by their needed precedence. This is the point the new MultiTasking Module of Kithara lounches into.
The Berlin company Kithara Software recently extended the current product range RealTime Suite 2008 with multi-tasking capabilities, which copes with well-established real-time operating systems. It involves a priority based and preemptive which means superseding multi-tasking, which makes automatically sure, that the task the user classifies as the most important one is executed as appropriate.
The system provides up to 255 tasks, which can be designated to a different priority level. Common to all tasks is, that they are executed prior to every other Windows activity. This way, by the extension of the product range »RealTime Suite 2008« the user gains the possibility to realize complex real-time systems with an accuracy around only a few microseconds. Multiple timers can be programmed both cyclically and one-shot with frequencies of more than 10 kilohertz.
Using a suspend/resume mechanism the software provides functions to block distinct tasks temporarily. This way users even gain the option to transfer “endless loops” from bygone days into forward-looking solutions. This was often an important obstacle, when former DOS-based control and automation systems had to be converted to modern Windows operating systems.
The multi-tasking application can be created by the developer as he used to do comfortably within the application development environment, which can be programmed in C/C++ or Delphi or embedded into a C#.NET application using a DLL.
