Multitask fast performance device in PLC system

摘要

The present invention relates to a multi-task fast performing apparatus in a PLC system. In the prior art, one interrupt task program has a single task structure in which another task cannot enter while the task is being executed. Since a task has been performed, there are many problems in that a number of task programs can be executed.;Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and provides an apparatus for determining the priority of a plurality of tasks at high speed, so that the priority of each task is determined at a high speed at a predetermined time. Therefore, the task is performed with the highest priority among the required tasks, and when the interrupt task is input from the high speed input device in the workplace, a corresponding task can be performed, thereby performing a plurality of tasks at high speed.
