SM130 HollySys Main Control Chassis, Real-time performance: The controller CPU adopts industrial-grade RISC chips, based on a real-time operating system, ensuring precise, real-time, and efficient control.
Reliability: Utilizes multiple redundancy structures (network redundancy, controller redundancy, power module redundancy, I/O module redundancy), ensuring system safety, stability, and reliability. The system is designed for harsh industrial environments, with interference resistance meeting industrial standards.
Flexibility: Flexible structure ensures both data consistency and load balancing; feature-rich HMI human-machine interface, flexible and powerful control software, supports offline simulation.
Ease of use: Intelligent device management (fault diagnosis, accuracy calibration, hot swapping), comprehensive system diagnostic information, online electronic maintenance manual, making maintenance simple and convenient.
Decentralization: Process I/O units adopt an intelligent design approach, distributing some control or acquisition operations to each I/O unit, improving reliability.
Openness: Open network system: Supports Profibus-DP fieldbus, provides standard RS-485, RS-232, ModBUS communication protocol interfaces, supports FF, CAN, HART, etc. Open operating system: Uses Windows XP operating system, provides ODBC and OPC interfaces, supports Internet access.
Continuity: Operator stations use a universal system platform, allowing synchronous upgrades as computer technology advances.
Cost-effectiveness: Fieldbus system design effectively saves overall project investment and reduces operation and maintenance costs.
Isolation principle: All I/O units employ reliable optoelectronic isolation and electrical isolation technologies, ensuring no electrical connection between units or between units and the controller, thereby enhancing system interference resistance, reliability, and safety. Isolation measures are also provided between different channels within the same unit and between the logic function side and field signal side.
Self-diagnosis: All units in the field control station are equipped with CPUs, each capable of periodic self-diagnosis. Diagnostics mainly include self-tests of CPU and memory, read-back comparison of digital outputs, correctness comparison and judgment of analog input channels, correctness comparison of analog output channels, etc. Diagnostic results are uploaded to the system status diagram of the host computer every second for display, supporting web-based remote diagnosis functionality.
