GE DS215UCVBG3A (1 E-Net, 2 DLAN+, 2 GENIUS, uses 4 slots)

The primary function of the DS215UCVBG3A is to serve as a versatile communication hub and processor, integrating the turbine control system with various internal and external networks. It is part of the VME (VERSAmodule Eurocard) rack-based system, a common industrial bus standard. Its key roles include:

  • Communication Interface: The board provides multiple communication ports to interface with different networks, which is crucial for a complex, plant-wide control system.
    • Ethernet (1 port): Allows the control system to connect to plant-wide networks, such as a SCADA (Supervisory Control and Data Acquisition) system, for remote monitoring, data logging, and supervisory control.
    • DLAN+ (2 ports): This is GE’s proprietary Drive Local Area Network, used for high-speed, redundant communication between various modules within the Mark V system, including redundant processors. The inclusion of two ports enhances its redundancy and communication capabilities.
    • Genius LAN (2 ports): A proprietary communication protocol used by GE Fanuc for industrial automation, allowing the board to interface with other Genius-enabled devices. The two ports enable redundant communication, which is a key feature of the Mark V’s fault-tolerant architecture.
  • Central Processing: The board is equipped with a 586-133 Pentium Processor that handles the real-time processing and communication of data from these various networks.
  • System Integration: It is a key part of the overall control architecture, providing the necessary connectivity to integrate the turbine control system with other plant systems.

الوصف

The GE DS215UCVBG3A is a specialized Unit Controller 2000/VME Board for the GE Mark V series of turbine and generator control systems. It is a high-performance communication and processing card designed for a specific set of network connections. It is a more robust and feature-rich version compared to the DS215UCVBG1A, as indicated by its more extensive I/O and larger form factor.

 

Function and Purpose

 

The primary function of the DS215UCVBG3A is to serve as a versatile communication hub and processor, integrating the turbine control system with various internal and external networks. It is part of the VME (VERSAmodule Eurocard) rack-based system, a common industrial bus standard. Its key roles include:

    • Ethernet (1 port): Allows the control system to connect to plant-wide networks, such as a SCADA (Supervisory Control and Data Acquisition) system, for remote monitoring, data logging, and supervisory control.
    • DLAN+ (2 ports): This is GE’s proprietary Drive Local Area Network, used for high-speed, redundant communication between various modules within the Mark V system, including redundant processors. The inclusion of two ports enhances its redundancy and communication capabilities.
    • Genius LAN (2 ports): A proprietary communication protocol used by GE Fanuc for industrial automation, allowing the board to interface with other Genius-enabled devices. The two ports enable redundant communication, which is a key feature of the Mark V’s fault-tolerant architecture.
  • Central Processing: The board is equipped with a 586-133 Pentium Processor that handles the real-time processing and communication of data from these various networks.
  • System Integration: It is a key part of the overall control architecture, providing the necessary connectivity to integrate the turbine control system with other plant systems.

 

Technical and Design Features

 

The DS215UCVBG3A is a robust, industrial-grade circuit board designed for reliability in harsh environments.

  • VME Bus: It is a VME board, meaning it plugs into a VME backplane within a control cabinet. As noted in your query, it occupies 4 slots in the VME rack, a larger footprint compared to the 2-slot DS215UCVBG1A, reflecting its enhanced communication capabilities and more complex hardware.
  • “DS215” Designation: The “DS215” prefix in the part number indicates that it is a 2-series board, a later generation of GE’s control cards, signifying it is an updated version of the original DS200 series. The “G3” suffix indicates a specific group or revision with added features.
  • Power Requirement: The board requires -12 VDC at approximately 200 mA and uses the P1 VME connector for power.

 

Applications and Importance

 

The DS215UCVBG3A is a fundamental component of the GE Mark V system, which is widely used in power generation. The ability to have high-speed, reliable, and redundant communication across different network protocols is what allows the Mark V system to operate with a high degree of precision and fault tolerance. Without this board, the system’s ability to communicate between its redundant cores and to remote operator stations would be severely impaired, potentially leading to a system shutdown.
