The implementation of automated control for fermentation processes based on the Siemens S7-1500 series PLC involves a range of critical features. These include filter sterilization, air consumption, liquid consumption, cultivation, and inoculation. The system allows precise control over parameters such as temperature, pressure, flow rate, rotational speed, pH, and dissolved oxygen. Additionally, the process is monitored, controlled, and data is collected and automatically saved using PC-based HMI software WinCC.
