GE DS200SLCCG1ABA LAN Communications Card

الوصف

The GE DS200SLCCG1ABA is a specific revision of the LAN Communication Card ($\text{SLCC}$), a board critical to network operations within the GE Mark V Speedtronic Turbine Control System.

Its core function is to provide the hardware interface and processing required to manage communications across industrial networks for the drive or exciter control system.

Technical Function and Features

• Networking Protocols: As a $\text{G1}$ variant, the $\text{DS}200\text{SLCCG1ABA}$ includes the necessary circuitry to support both of GE’s key proprietary industrial network standards used in the Mark V series:
  • DLAN (Drive LAN)¹

     

  • ARCNET
• Processor & Data Flow:
  • It utilizes a dedicated LAN Control Processor ($\text{LCP}$) to handle network traffic and protocols.
  • Communication between the $\text{LCP}$ and the main Drive Control Processor ($\text{DCP}$) (on the main control board) occurs through high-speed Dual-Ported RAM ($\text{DPR}$).
• Software: The operating code for the $\text{LCP}$ is stored on two removable $\text{EPROMs}$ ($\text{U}6$ and $\text{U}7$). These chips contain critical firmware and must often be transferred to a replacement card during maintenance.
• Diagnostics: The card has a port (²$\text{KPPL}$) that allows connection of a Programmer Module (a keypad with a 16-character alphanumeric display), providing local access for diagnostics and setting control parameters.³

   

• Physical Style: The “G” in the part number indicates it uses the Normal Style PCB coating (standard industrial protection).
