Breaking Conventional PLC Timing Experiments: Cycle Time Counting vs Cycle Interrupts, Guess Which Method Has Higher Accuracy?

Breaking Conventional PLC Timing Experiments: Cycle Time Counting vs Cycle Interrupts, Guess Which Method Has Higher Accuracy?

Introduction INTRODUCTION In industrial automation programming, timers are one of the most commonly used components in control logic. While standard timers like TON and TOF can meet most scenarios, are there more flexible implementations for situations that require special timing accuracy or want to break free from “relying on the system’s default timer”? A user … Read more

Disadvantages of Polling Method for Timer Control in Microcontrollers

Disadvantages of Polling Method for Timer Control in Microcontrollers

Regardless of the type of microcontroller, timer functionality is essential and relies on timers/counters, which are the most basic configurations of a microcontroller. Timing is primarily accomplished by hardware, while timing control is mainly handled by software. There are two methods for timing control: polling and interrupt methods. Each has its advantages and disadvantages, but … Read more
