GE DS200UCPBG5ADA IO Engine CPU Board

الوصف

The GE DS200UCPBG5ADA is a critical component in the General Electric Mark V Speedtronic Turbine Control System.¹ It is the I/O Engine Central Processing Unit (CPU) Board.

🚀 Primary Function: The Core Processor

The UCPB (UC2000 Processor Board) is the brain of the Input/Output (I/O) section within the control cores (²$R1, R2, R3$, and ³$R5$ I/O engines).⁴ Its main functions are to execute control algorithms, manage I/O data, and facilitate communication for the Triple Modular Redundancy (TMR) system.

1. Processing and Execution

• CPU: The board contains the main control processor, typically a 486-class (80486DX) or similar industrial-grade CPU, responsible for running the turbine’s sequence and protection algorithms.⁵
• Memory: It utilizes memory modules, such as SIMM (Single Inline Memory Module) sockets for DRAM (Dynamic RAM) and EPROM (Flash Erasable PROM) to store the operating system, firmware, and application software.⁶

2. Data Management and Communication

• I/O Packaging: The processor packages all the acquired analog and digital I/O data from the various field devices.⁷
• COREBUS Broadcast: It broadcasts this packaged data onto the COREBUS (via an onboard ARCNET driver) for use by the main T, R, and S control cores.⁸
  • Fast Packets: Critical, high-priority data is broadcast at a high rate (e.g., ⁹$100 \text{ Hz}$ or every ¹⁰$10 \text{ ms}$).¹¹
  • Slow Packets: Less critical information is broadcast at a slower rate.
• I/O Configuration: It stores and loads the I/O configuration data for the respective I/O engine, ensuring correct mapping and scaling of signals.¹²

3. Physical Interface

The UCPB is a daughterboard that plugs directly into a mother board, such as the DS200UCIBG3AAB, which provides the connectors to the rest of the control circuitry.¹³

🔢 Part Number Breakdown

The specific part number DS200UCPBG5ADA provides detailed information about its generation and revision:

The G5 designation places this board within a specific hardware grouping of the Mark V system, differentiating it from G4 or G6 versions that might use slightly different processors, memory configurations, or I/O interfacing schemes.
