A demonstration automation system based on the Siemens PCS7 platform has been provided to achieve batch automation control for the tank system used in oligonucleotide production, facilitating processes such as cleavage, deprotection, quenching, and annealing reactions. The system integrates real-time data from third-party equipment like synthesizers, chromatography, and ultrafiltration onto this platform.

The system's hardware is based on the S7-410 Smart CPU, paired with ET200SP and corresponding AI, AO, DI, DO cards. It adopts a server/client architecture, integrating OS server, Batch server, OS client, and Batch client on two IPCs, one of which is an explosion-proof IPC.

Complete quality management documentation has been provided, configuring the PCS7 system with electronic signatures, audit trails, user management, data security, and other GAMP-related functions, and completing the relevant CSV validation.
