GE DS200SLCCG1AAA LAN Communication Card

الوصف

The GE DS200SLCCG1AAA is a specific revision of the LAN Communication Card (¹$\text{SLCC}$), a core component used in the GE Mark V Speedtronic Turbine Control System and associated drive/exciter systems (²$\text{SC}2000/\text{UC}200\text{V}$).³

Its primary function is to provide the dedicated processing and hardware interface necessary for the control system to communicate over a Local Area Network ($\text{LAN}$).

Key Features and Technical Role

The $\text{SLCC}$ is designed to manage complex networking tasks for the main control processor:

• Networking Protocols: As a ⁴$\text{G1}$ version card, the ⁵$\text{DS}200\text{SLCCG1AAA}$ includes the necessary circuits to support both DLAN (Drive LAN) and ARCNET communication standards.⁶ These networks facilitate the exchange of control signals, operational data, and diagnostics within the control system and to higher-level plant systems.

   

• Processor and Memory:
  • It features a dedicated LAN Control Processor (⁷$\text{LCP}$) to handle communication traffic.⁸

     

  • It utilizes Dual-Ported RAM ($\text{DPR}$) for high-speed, shared communication between the $\text{LCP}$ and the main drive control processor ($\text{DCP}$) on the system’s control board.
  • The $\text{LCP}$‘s operating software is stored on two removable $\text{EPROMs}$ ($\text{U}6$ and $\text{U}7$), which are often proprietary and must be transferred when the board is replaced.
• Diagnostics: The card includes a connection point (⁹$\text{KPPL}$) for a Programmer Module (keypad and 16-position alphanumeric display) that allows technicians to access and configure diagnostics and system parameters directly at the drive cabinet.¹⁰

   

• Form Factor: It is a standard $\text{VME}$ bus card, designed to mount onto the $\text{Drive Control Card}$ ($\text{SDCC}$) or within the $\text{VME}$ rack.
• PCB Coating: The “G” in the part number indicates it uses the Normal Style PCB coating (standard protection), rather than the more robust conformal coating found on “H”-designated boards.
