GE DS200SLCCG1AFG LAN Communication Card

الوصف

The GE DS200SLCCG1AFG is a specific, later revision of the LAN Communication Card ($\text{SLCC}$), which is an integral component within the GE Mark V Speedtronic Turbine Control System and associated drive/exciter control platforms.

Its fundamental purpose is to provide the required hardware and dedicated processing power to manage and facilitate Local Area Network ($\text{LAN}$) communications for the main controller.

Key Technical Details

• System Role: The $\text{SLCC}$ manages high-speed, reliable data transfer for critical operational parameters, control commands, and diagnostics between the controller and other network components.
• Networking Protocols: As a $\text{G1}$ variant, the $\text{DS}200\text{SLCCG1AFG}$ features the circuitry to support both of GE’s proprietary industrial networks common in Mark V systems:
  • DLAN (Drive LAN)¹

     

  • ARCNET
• Dedicated Processor: The card utilizes a dedicated LAN Control Processor ($\text{LCP}$) to efficiently handle network traffic and protocols, thereby minimizing the workload on the main Drive Control Processor ($\text{DCP}$).
• Data Interfacing: Communication between the ²$\text{LCP}$ and the ³$\text{DCP}$ is executed via high-speed Dual-Ported RAM (⁴$\text{DPR}$).⁵

   

• Firmware: The $\text{LCP}$‘s operating software is stored on two removable $\text{EPROMs}$ ($\text{U}6$ and $\text{U}7$). These chips are application-specific and must be transferred to a replacement board.
• Physical Style: The “G” in the part number indicates it has the Normal Style PCB coating (standard industrial protection).
