Product Overview

Core Functions

1. Core Control Computing: Executes closed‑loop control algorithms, sequential logic, protection interlocks, and fault diagnostics for turbine speed, load, temperature, pressure, etc., meeting millisecond‑level real‑time control requirements.

2. High‑Speed Data Processing: Processes analog/digital signals from field I/O, sensors, and actuators, completing data acquisition, filtering, calibration, storage, and upload.

3. Multi‑Protocol Communication: Provides 10/100Base‑TX Ethernet (RJ45), VME bus, and serial (COM1) communication to connect UDH, I/O modules, HMI, and supervisory systems, supporting GE proprietary buses and standard industrial protocols.

4. Real‑Time Operating System: Runs the QNX real‑time OS for multi‑task parallel processing, low‑latency response, and high stability in harsh industrial environments.

5. Fault Self‑Diagnosis & Redundancy: Built‑in hardware self‑test, watchdog, and power monitoring; supports system redundancy for fast failover to improve continuous operation.

6. Plug‑and‑Play Compatibility: Standard VME single‑slot form factor, directly compatible with Mark VI cabinet backplanes, and seamlessly interfaces with IS200/IS220 series I/O modules.
