Technical details and manufacturing context for Central Processing Unit (CPU)/Controller

Definition
Within an Integrated Process Control System (PCS), the Central Processing Unit (CPU)/Controller serves as the primary computational and decision-making component. It executes the control program, processes input data from sensors and field devices, performs calculations, and sends output commands to actuators and other system components to regulate the industrial process according to the defined setpoints and logic.
Working Principle
The CPU/Controller operates by continuously cycling through a scan cycle: reading input statuses from connected I/O modules, executing the stored control program (ladder logic, function blocks, etc.), performing any necessary computations or PID control algorithms, and then writing output values to the output modules to control the physical process. It manages system timing, communication with other devices (HMIs, networks), and handles fault diagnostics.
