However, their role and efficiency depend on the complexity of the application
In this article, we explore how a plc operates.
For minor automation tasks, a plc can work without scada However, scada is useful for central monitoring, trending, and analyzing historical data in bigger systems. In summary, scada, hmi, and plc are three vital components of industrial automation, but they each operate at different levels of the control hierarchy The plc is the workhorse at the ground.
