Technical details and manufacturing context for Control System (HMI/PLC)

Definition
The Control System (HMI/PLC) serves as the central nervous system of the Automated Pharmaceutical Lyophilization System, integrating HMI for operator interaction and visualization with PLC for real-time process control, data acquisition, and automated sequencing of freeze-drying operations including temperature regulation, vacuum control, and cycle management.
Working Principle
The PLC executes programmed logic to control physical devices (valves, pumps, heaters) based on sensor inputs, while the HMI provides graphical interface for monitoring process variables, setting parameters, displaying alarms, and generating reports through communication protocols like Ethernet/IP, Profibus, or Modbus.
