Detailed explanation of the core functional modules of the system

（1） Operation module: Focus on efficient and intuitive operation

Integrated Management: Integrating the three major goals of production excellence, safety excellence, and asset excellence, optimizing data management through cognitive vision integration, HIS (Human Machine Interface Station) can uniformly display alarm information from DCS, ProSafe RS, and PRM systems, achieving seamless cross system operation

Human Machine Interface (HMI):

Design philosophy: Putting people first, based on ergonomics, adapting color matching to environmental lighting, optimizing contrast, and ensuring high visibility of data

Flexible configuration: supports multi screen display and custom windows, can group commonly used functions through "My Favorites", and quickly call past interfaces through "Window History"

Advanced Services: AOG (Advanced Operating Graphics) solution, designed by certified consultants based on human factors and knowledge engineering to enhance anomaly detection efficiency and decision-making speed in PCS graphics

Specialized operation keyboard: provides two types of simultaneous operation for single circuit and eight circuit, optimized function key layout, supports one click calling of graphics or control circuits, and helps operators quickly respond to process changes

Virtualization technology: decoupling system software from physical hardware, supporting software reuse and smooth hardware migration, shortening migration and testing time, and reducing maintenance difficulty

（2） Control module: ensuring high availability and stable control

High availability design:

Dual redundancy architecture: The FCS processor module, power supply, I/O module, and I/O network are all designed with dual redundancy. The primary and backup processors run synchronously, seamlessly switching in case of failure to ensure uninterrupted control

Online maintenance: supports FCS application logic and parameter online modification, fault modules can be replaced online without downtime, and does not affect the production process

Core Control Unit (FCS): independently developed and manufactured by Yokogawa, with powerful processing capabilities and large capacity application storage, fully adapted to advanced on-site digital technology, ensuring control efficiency and stability

Control network (Vnet/IP):

Technical specifications: Compliant with IEEE802.3 Ethernet standard, with a transmission rate of 1Gbps, supporting both star and ring topologies

Core advantage: It combines openness and security, does not affect the transmission of process control data, ensures HIS updates data every second, and adapts to projects of different sizes and complexities

I/O module selection:

N-IO (Network I/O): The next generation of software can configure intelligent I/O, with a single module supporting AI/AO/DI/DO signals. Signal type software configuration is achieved through adapters, reducing installation delays and eliminating the need for traditional wiring grouping, saving space and cost. It can be deployed as a remote I/O module
