Core Functional Features

1. High-Speed Real-Time Cyclic Control Operation: The processor executes control logic programs in a fixed 10ms minimum control cycle, supporting up to 1000 independent PID closed-loop regulation loops for industrial process temperature, pressure, flow and liquid level parameters
2. Dual Redundant Hot Standby Master-Slave Architecture: Two RH100CP modules can form a fully redundant control processor pair; the slave processor synchronizes all real-time process data and logic operation results with the master processor in real time, and completes seamless hot backup switching within 15ms when the master module fails, with zero interruption of process control output
3. Massive Field Bus I/O Expansion Capacity: Dual FBM expansion bus interfaces support simultaneous docking of up to 64 groups of RH series FBM remote I/O modules, realizing centralized collection and control of thousands of field analog and digital signals
4. Complete Multi-Protocol Industrial Communication Compatibility: Built-in standard communication protocol libraries including Modbus TCP/RTU, HART, OPC UA, PROFIBUS-DP; seamless data exchange with third-party industrial transmitters, frequency converters, PLC controllers and monitoring host equipment
5. Independent Hardware Watchdog Safety Circuit: Each RH100CP module is equipped with a hardware watchdog timer powered by an independent backup battery; when the program crashes, communication is lost or the processor runs abnormally, the watchdog circuit automatically triggers a full module reset and switches all output channels connected to the FBM bus to pre-set fail-safe safety state
6. Built-in Full BIST Hardware Self-Test & Precise Fault Diagnosis: The module automatically completes comprehensive self-inspection of the processor core, all memory banks, dual Ethernet channels, dual FBM expansion buses and serial communication ports after power-on; during normal operation, it continuously monitors the operating state of all hardware circuits, and uploads accurate fault location codes to the central operation monitoring station through the Ethernet network once any hardware fault is detected
7. Large-Capacity Historical Process Data Local Storage: The built-in 128MB Flash storage chip supports local storage of up to 30 days of real-time process historical data, equipment operating parameter records and fault alarm event logs; stored data will not be lost after the module power supply is cut off
8. Online Remote Firmware & Control Logic Configuration Upgrade: Support remote online update of the module’s underlying firmware program and industrial process control logic configuration files through the Ethernet control network; the upgrade process does not require cutting off the module power supply or stopping the industrial field control operation, and automatically rolls back to the original stable program version if the upgrade fails
9. Configurable Multi-Group Independent Fail-Safe Output Logic: Users can independently set the safety open-circuit or closed-circuit state of all digital output channels and analog output channels connected to the FBM bus when the RH100CP module fails or the network communication is interrupted, adapting to different safety protection requirements of various industrial production processes
10. Multi-Channel Real-Time Alarm Classification & Transmission Function: The module supports multi-level alarm classification configuration including process over-limit alarm, equipment fault alarm, communication interruption alarm and module hardware fault alarm; all alarm information carries precise time stamps and equipment location tags, and is synchronously uploaded to the central monitoring host, local on-site operation panel and remote alarm notification terminal through dual redundant Ethernet networks
