Function Features

• 1+1 Redundant Architecture: Eliminates single points of failure with hot standby operation and ≤100 ms automatic failover. Ensures uninterrupted process control in critical applications (e.g., nuclear power, chemical reactors).
• High-Speed Processing: Dual-core 1.2 GHz CPU and 2 GB ECC RAM enable fast execution of complex control logic (e.g., multi-loop PID, batch sequencing) and real-time processing of thousands of I/O points.
• Multi-Protocol Communication: Supports PROFINET IRT, Modbus TCP, Ethernet/IP, and IEC 61850—enabling seamless integration with third-party PLCs, HMIs, SCADA systems, and smart field devices (e.g., IoT sensors).
• ECC Memory & Data Backup: ECC RAM corrects single-bit errors and detects multi-bit errors to prevent data corruption. NVRAM with supercapacitor backup retains critical configuration and process data for 72 hours without power.
• Advanced Diagnostics: Monitors hardware health (CPU temperature, power supply status, communication links) and software performance (control cycle time, I/O error rates). Generates detailed fault logs with time stamps for rapid troubleshooting via 800xA HMI.
• Scalable I/O Integration: Connects to up to 32 S800 I/O modules via CEX-Bus, supporting digital, analog, and specialty I/O (e.g., temperature, vibration). Enables flexible expansion for large-scale industrial systems.
• IEC 61131-3 Compliance: Supports all standard programming languages (ladder logic, function block diagram, structured text, sequential function chart)—simplifying logic development and reducing engineering time.
• Rugged Industrial Design: Withstands -25°C to +70°C temperatures, vibration, and electromagnetic interference. Robust enclosure and thermal management ensure reliable operation in harsh settings (e.g., mines, refineries).
