II. Functional Features

1. Multi-Core Parallel Computing for Enhanced Control Real-Time Performance: Adopting a multi-core architecture, the main core is responsible for core control logic computing, while the auxiliary cores handle communication interaction and fault diagnosis, avoiding overload of a single core.

5. Multi-Protocol Compatibility for Cross-System Interconnection: Natively supports mainstream protocols of industrial Ethernet and fieldbuses, enabling seamless connection with equipment of brands such as GE, Siemens, and Rockwell, easily breaking the "protocol island". It realizes data intercommunication between the control layer and the information layer through Gigabit Ethernet, supporting intelligent manufacturing data collection in Industry 4.0 scenarios.
6. 
   
7. Intelligent Diagnosis and Maintenance to Reduce Management Costs: Built-in full-link diagnosis function covering "module-channel-communication". Fault information is indicated by both LED indicators and diagnostic software, with a positioning accuracy reaching the channel level. It supports remote program download, online debugging, and firmware upgrade, reducing on-site operation and maintenance workload.

III. Working Principle

1. Data Collection: On-site sensor signals (such as temperature, pressure, and position) are collected through I/O modules and transmitted to the CPU via the internal bus. The signal transmission process undergoes filtering and isolation treatment to suppress electromagnetic interference.
2. 
   
3. Computing Processing: The multi-core processor calls preset control programs (such as logic interlocking and PID regulation). The main core executes core computing, while the auxiliary cores synchronously process communication data and diagnostic information, realizing real-time data interaction through shared memory.
4. 
   
5. Control Output: The computing results are converted into execution signals by the output module to drive the action of executive mechanisms such as valves and motors. In redundancy mode, the standby CPU verifies the main core data in real time to ensure output consistency.
6. Status Feedback: It monitors the operating status of each module in real time, and uploads fault information and operating data to the HMI or SCADA system to realize visual monitoring and fault early warning.

IV. Typical Application Scenarios

1. Intelligent Manufacturing Production Lines: Used for collaborative control of production lines such as automobile welding and electronic component assembly. It realizes multi-equipment linkage and precise adjustment of process parameters, improving production efficiency by more than 15%.
