A virtualization SCADA solution based on Stratus ftServer has been provided, utilizing the Siemens WinCC system to achieve real-time 3D visual display of the automation systems of various process units in the upstream and downstream workshops. This solution enables key information collection, alarm handling, historical data archiving, database backup, time synchronization, and large screen display functionalities, as well as completing the migration and validation of historical data from the PCS7 system. The WinCC system employs the OPC DA communication protocol for real-time data acquisition and alarm processing of process equipment on the Siemens platform (such as bioreactors, virus removal filtration, ultrafiltration, BMS, water systems, etc.), and uses the OPC UA communication protocol for real-time data acquisition and alarm processing of process equipment on the DeltaV platform (such as chromatography and online liquid preparation).
