In industrial automation, the programmable logic controller (PLC) relies on its central processing unit (CPU), the system’s brain, to ensure precise and reliable control. The CPU executes user-defined logic, interprets instructions, reads inputs, processes data, and generates outputs for actuators and other devices. It manages memory for programs, data, and settings, preventing corruption while supporting efficient operation. Modern CPUs enable seamless communication with networks, devices, and HMIs, handle protocols, and perform self-diagnostics. Their processing power, memory, and advanced features are essential for performance, reliability, and productivity.
