Functional Features

1. Millisecond-Precision Time-Stamping

   Provides 1 ms resolution time-stamping for every digital event. This ultra-high precision ensures accurate sequencing of events, critical for determining the exact order of process trips, equipment failures, or alarm activations during incident investigations.

2. Centralized SOE Network Management

   Acts as the centralized master, managing and coordinating up to 1,500 SOE input points distributed across 1,000 HCUs. It efficiently polls, collects, and consolidates event data from a vast network, creating a unified system-wide event log.

3. Advanced Trigger Configuration

   Supports a comprehensive trigger system with 3,000 simple triggers and 256 complex triggers. Complex triggers enable sophisticated event logic using multiple operands, allowing users to define highly specific conditions for event capture and system response.

4. Precise Time Synchronization

   Maintains absolute time accuracy by synchronizing in real-time with the INTKM01 Time Keeper Master module. This ensures all events across the entire distributed system are stamped with a unified, precise time reference, eliminating time drift discrepancies.

5. High-Speed Data Buffering & Sorting

   Features high-speed internal buffering to capture events without data loss during peak system activity. The module automatically sorts acquired events by time stamp, ensuring a chronologically accurate sequence ready for instant retrieval and analysis.

6. Exception-Based Communication

   Operates on an exception-reporting basis, only transmitting data when an event or state change occurs. This optimizes backplane and network bandwidth usage, ensuring efficient system performance even under full SOE capacity.

7. Hot-Swappable Design

   Supports hot-swapping, allowing for installation, removal, or replacement while the DCS remains fully powered. This minimizes system downtime and simplifies maintenance without interrupting critical event recording.

8. Robust Industrial Reliability

   Constructed with industrial-grade components for operation in extreme temperatures and harsh electrical environments. It offers superior immunity to EMI and electrical noise, guaranteeing uninterrupted SOE functionality in demanding industrial settings.

9. Seamless System Integration

   Integrates natively with INFI 90/Symphony DCS components (INNIS11, INTKM01) and human-machine interfaces (HMI). It provides structured SOE data for real-time display, historical archiving, and comprehensive reporting.

Application Scenarios

• Power Generation (Thermal, Hydro, Nuclear)

  Monitors and records critical events in boiler systems, turbine controls, generator protection, and switchgear operations. Essential for analyzing unit trips, load rejections, and safety system actuations to ensure grid stability.
