Troubleshooting High CPU Load and Task Overruns in Modicon M580 Controllers

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.
