Function Features

• Ultra-Fast Redundant Failover: ≤ 50 ms automatic switchover between active and standby units ensures no process interruption—critical for applications like nuclear power, chemical reactors, and oil refining where downtime causes massive losses.
• High-Speed Processing: Dual-core 1.0 GHz PowerPC CPU and 1 GB ECC RAM enable simultaneous execution of complex control logic and real-time processing of thousands of I/O points, supporting high-speed manufacturing lines and dynamic process control.
• Multi-Protocol Compatibility: Supports PROFINET IRT (for synchronized motion control), IEC 61850 (for smart grids), and Modbus TCP/RTU—enabling seamless integration with third-party PLCs, IoT sensors, and upper-level SCADA systems.
• ECC Memory & Long-Term Data Backup: ECC RAM corrects single-bit errors and detects multi-bit errors to prevent data corruption. Lithium-backed NVRAM retains critical configuration and process data for 10 years, ensuring system recovery after prolonged power loss.
• Advanced Diagnostics & Monitoring: Real-time monitoring of hardware health (CPU temperature, power supply voltage, communication link status) and software performance (control cycle time, I/O error rates). Generates detailed fault logs with time stamps for remote troubleshooting via 800xA HMI.
• Scalable I/O Integration: Connects to up to 64 S800 I/O modules (digital, analog, specialty) via dual CEX-Bus, supporting up to 8192 I/O points. Enables flexible expansion for large-scale systems like water treatment plants and steel mills.
