Issue
High CPU load and task overruns are typically caused by inefficient application logic, misconfigured task priorities, excessive communication polling, overuse of event tasks, or large data processing within a single scan cycle.
Resolution
This article provides a structured approach to diagnosing and resolving high CPU load and task overrun issues in Modicon M580 controllers. It focuses on identifying bottlenecks in cyclic and event tasks, using built-in diagnostic variables, understanding communication impact, and applying optimization techniques.
