GE DS200SLCCG1AEE LAN Communication Board

الوصف

The GE DS200SLCCG1AEE is a specific revision of the LAN Communication Card (¹$\text{SLCC}$), which is a key component for network connectivity in the GE Mark V Speedtronic Turbine Control System and associated drive/exciter control platforms.²

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

Technical Function and Features

• Networking Protocols: As a $\text{G1}$ variant, the $\text{DS}200\text{SLCCG1AEE}$ includes circuitry to support both of GE’s proprietary network standards used in the Mark V series:
  • DLAN (Drive LAN)³

     

  • ARCNET
• Dedicated Processing: The board features a LAN Control Processor (⁴$\text{LCP}$).⁵ This specialized processor handles complex network protocols and data filtering, reducing the processing load on the main drive control processor ($\text{DCP}$).

   

• Data Interfacing: High-speed, shared communication between the ⁶$\text{LCP}$ and the ⁷$\text{DCP}$ is accomplished via Dual-Ported RAM (⁸$\text{DPR}$).⁹

   

• Software Storage: The operating firmware for the $\text{LCP}$ is stored on two removable $\text{EPROMs}$ ($\text{U}6$ and $\text{U}7$). These chips contain critical, application-specific code and must be transferred from the old board to a new one during replacement.
• Diagnostics: The card has a port (¹⁰$\text{KPPL}$) that allows an optional Programmer Module (keypad and alphanumeric display) to be attached for local diagnostics and parameter viewing.¹¹

   

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