Intelligent control of solenoid valve group box: the nerve center of industrial automation

A recent success story shows how intelligent solenoid valve groups and control cabinet systems can improve production efficiency. A biopharmaceutical company in Shanghai uses a valve island control system provided by Wuxi Aiksen. The system is seamlessly integrated with Emerson's DeltaV card components through the Charm bus protocol.

In biopharmaceutical production, fluid control systems play a key role in processes such as drug synthesis, purification, and aseptic filling. However, traditional control systems are often complex in architecture, resulting in a higher risk of operational errors, longer commissioning cycles, and increased maintenance burdens. To meet these challenges, the Shanghai-based company embarked on a journey of technological upgrades. ​

By leveraging the high-speed, reliable communication standard Charm bus protocol, the system can be directly connected to Emerson's DeltaV distributed control system (DCS) without the need for additional converters or complex middleware. This direct connection establishes a seamless data flow that enables operators to accurately monitor and manage the solenoid valve island. Integrated diagnostic functions can detect faults immediately, thereby facilitating proactive maintenance and minimizing downtime. ​

During the implementation process, our team conducted rigorous testing to ensure perfect interoperability between components. Ultimately, the system is responsive and meets the stringent Good Manufacturing Practice (GMP) requirements for biopharmaceutical production while improving overall operational efficiency. The simplified control architecture streamlines workflow, reduces human errors and speeds up troubleshooting. ​

This integration enables precise control and real-time diagnostics of the solenoid valve island, effectively reducing system complexity and significantly saving time and labor costs.
