GE IC695CRU320 Redundant processor module

The IC695CRU320 is a redundant processor module in GE PACSystems RX3i series, primarily designed to enhance system reliability and availability, ensuring continuous operation when the main processor fails. The detailed introduction is as follows:

• Processor: Equipped with high-performance processors such as Intel Celeron M or ARM Cortex A8, providing strong computing power to support complex control tasks and multitasking.

• Memory: 512MB RAM and 64MB flash memory, ensuring sufficient space for program operation and data storage.

• Power Requirements: Operates at 24V DC with a maximum power consumption of 6.5W, featuring low power consumption suitable for most industrial power supply environments.

• Communication Interfaces: Supports multiple communication protocols including RS-232, RS-485, and Ethernet, facilitating connection and data interaction with other devices or systems.

• Dimensions and Weight: Standard size is 175mm x 150mm x 71mm, weighing approximately 0.9kg, with moderate volume and weight for easy installation and layout.

• Protection Level: IP65, offering excellent dust and water resistance to ensure reliable operation in harsh industrial environments.

• Temperature Range: Operating temperature: -40°C to +85°C; storage temperature: -40°C to +85°C, demonstrating strong adaptability to temperature changes.

• Hot Standby Mechanism: Supports real-time synchronous operation of primary and standby CPU modules, with automatic switching to the standby module when the primary fails, ensuring continuous system operation with a switching time <100ms.

• State Synchronization Technology: Real-time synchronization of program data, register status, and I/O mapping via a dedicated redundant communication link (e.g., RX3i backplane) to ensure no data loss during primary-standby switching.

• Redundancy Health Monitoring: Built-in hardware monitoring circuit continuously monitors the operation status of primary and standby modules, alarming via indicator lights and communication interfaces in case of anomalies.

• Processor Configuration: Adopts a 1 GHz PowerPC processor with 64MB user memory (RAM) and 64MB flash memory, supporting floating-point operations and high-speed logic processing.

• Instruction Execution Efficiency: Boolean instruction execution speed reaches 0.06ms/k, superior to non-redundant CPUs, meeting high real-time control requirements.

• Storage Expansion: Supports SD card expansion (requires adapter) for storing large programs, historical data, or recipe files, with battery-backed RAM ensuring data retention during power outages.

• Ethernet Port Redundancy: Equipped with 2 x 10/100 Mbps Ethernet ports supporting protocols like Modbus TCP, Ethernet/IP, and EGD. Port 2 supports ring network redundancy (MRP protocol) with fault recovery time <50ms.

• Backplane and Remote I/O Redundancy: Connects to local I/O modules (up to 32) via RX3i PCI bus, supports remote I/O expansion (e.g., Genius bus, PROFINET), and allows redundant communication link configuration.

• Serial Interface Compatibility: 2 x RS-232/RS-485 serial ports (software-configurable) supporting Modbus RTU, SNP, etc., compatible with legacy devices.

• Power and System Redundancy: Supports redundant power module configuration, combined with redundant processors for hot standby, reducing single-point failure risks.

• Security Protection: Program encryption and password protection prevent unauthorized access; built-in watchdog timer monitors operation in real time, auto-resetting or triggering redundant switching in case of anomalies.

• Environmental Adaptability: Standard operating temperature 0°C~60°C (extended type -20°C~60°C), vibration resistance 5g, shock resistance 50g (complying with IEC 60068 standards), suitable for harsh industrial environments.

• Programming Environment Compatibility: Supports GE PAC Control programming software, adheres to IEC 61131-3 standards (five languages: LD, FBD, ST, IL, SFC), and enables structured programming and modular design.

• Online Diagnosis and Switching: Supports online programming and remote diagnosis; primary-standby module status can be monitored in real time via software, allowing faulty module replacement without shutdown during maintenance.

• Redundancy Configuration Flexibility: Can be paired with PNC001 redundancy module to quickly build redundant systems, suitable for small-to-medium and medium-to-large control scenarios (e.g., production lines, process control).

• Typical Applications:

• Process control scenarios requiring continuous operation in chemical, power industries (e.g., PID loop control, safety interlock systems).

• Automation production lines sensitive to downtime in automotive manufacturing, packaging machinery, etc.

• Distributed remote I/O master stations requiring highly reliable communication and control nodes.

• Comparison with Non-redundant Modules:

• Reliability Upgrade: Hardware redundancy and fast switching mechanism enhance system availability to over 99.99%, reducing downtime losses due to failures.

• Investment Protection: Compatible with RX3i series I/O modules and existing programming systems, enabling upgrade to redundant systems without redevelopment.

• Cost Optimization: Achieves high availability at a moderate cost compared to fully redundant large controllers, suitable for medium-scale redundancy requirements.

• Manufacturing: Used in automotive production line automation, mechanical equipment control, etc., to ensure stable production, improve efficiency, and product quality.

• Energy Management: Plays a role in monitoring and control of power plants, substations, and distribution networks to ensure reliable power supply.

• Chemical Industry: Applies to automation control of chemical processes, precisely monitoring and controlling various production links to ensure safety and product quality.

• Public Utilities: Such as heating, water supply, and wastewater treatment systems, enabling automated control and monitoring of infrastructure to improve management efficiency and service quality.
