    • In the process for controlling industrial operations and processes, a complex control program is processed by a microprocessor of a controller (10) under real-time conditions. The complex control program is divided into tasks. Each task is assigned a priority and an activation event. The activated task with the highest priority for processing is selected. Processing of a task can be interrupted on the basis of a subsequent request for processing a higher-priority task Processing of the lower-priority task is continued at the point of the interruption, after the processing of the higher-priority task is concluded. This process is characterized in that tasks can be divided into a number of subtasks to be processed sequentially, and within configurable, coherent and non-overlapping priority ranges, tasks can interrupt other lower-priority tasks only between two successive subtasks or at interruption points explicitly inserted by the user. Processing of the higher-priority task requested later is not begun until processing of the subtask during which the request for processing the higher-priority task was issued has been completed.
    • 在控制工业操作和过程的过程中,复杂的控制程序由控制器(10)的微处理器在实时条件下处理。 复杂的控制程序分为任务。 每个任务被分配优先级和激活事件。 选择处理优先级最高的激活任务。 任务的处理可以基于后续的处理较高优先级任务的请求而中断。在优先级高的任务的处理结束之后,中断点继续处理较低优先级的任务。 该过程的特征在于,任务可以被划分为要顺序处理的多个子任务,并且在可配置的,相干的和非重叠的优先级范围内,任务可以仅在两个连续的子任务之间或在中断点处明确地中断其他较低优先级的任务 由用户插入 在处理发出优先级较高的任务的请求的子任务的处理已经完成之前,才开始处理稍后请求的较高优先级任务。
