A demonstration automation system based on the Siemens PCS7 platform has been implemented to achieve batch automation control for production in synthesis workshops, recovery workshops, tank farms, sterile API workshops, and formulation workshops. It fully automates processes such as tank feeding, initialization checks, inertization, liquid solvent addition, solid material charging, TCU temperature control, pH-controlled dropping, and extractant addition. Real-time data from third-party equipment—including chromatographs, rotary evaporators, drying ovens, medium/low-pressure preparation systems, TCU units, integrated high/low-temperature machines, dry screw vacuum pumps, washing-filtering-drying tri-function units, centrifuges, purified water systems, chillers, cooling towers, nitrogen generators, oil-free vacuum machines, and air conditioning systems—are integrated into the DCS system via PN communication, Modbus RTU, Modbus TCP, and hardwiring. This enables real-time monitoring, alarm management, and remote control.

The system hardware is based on AS410-5H redundant controllers, paired with ET200 Smart+ modules and corresponding AI, AO, DI, DO cards. It adopts a server/client architecture, integrating domain control servers, OS redundant servers, Batch redundant servers, and PH redundant servers within a VMware virtualization framework. Engineering stations and operator stations are standalone PCs located in the central control room and workshop areas respectively.

Comprehensive quality management documentation has been provided. The PCS7 system has been configured with GAMP-related functions, including electronic signatures, audit trails, user management, and data security, along with completion of the corresponding CSV validation.
