GE DS200SLCCG1AEF LAN Communication Board

الوصف

The GE DS200SLCCG1AEF is a specific revision of the LAN Communication Card (¹$\text{SLCC}$), which is a key component in the GE Mark V Speedtronic Turbine Control System and associated drive/exciter control platforms.²

Its primary function is to provide the dedicated hardware and processing necessary for the control system to communicate over a Local Area Network (³$\text{LAN}$).⁴

Key Features and Role

• System Application: The board is part of the ⁵$\text{DS}200$ series for the ⁶$\text{Mark V}$ turbine and drive control systems, providing essential LAN interfacing capabilities.⁷

   

• Networking Support: As a ⁸$\text{G1}$ variant, it includes the circuitry to support GE’s proprietary DLAN (Drive LAN) and the older ARCNET communication protocols.⁹ It offers both isolated and non-isolated communication circuits.¹⁰

   

• Dedicated Processor: It incorporates a specialized LAN Control Processor (¹¹$\text{LCP}$) to manage and filter network traffic, offloading this burden from the main system control processor (like the ¹²$\text{DCP}$ on the ¹³$\text{SDCC}$ card).¹⁴

   

• Data Exchange: Communication between the ¹⁵$\text{LCP}$ and the main control processor uses high-speed Dual-Ported RAM (¹⁶$\text{DPR}$).¹⁷

   

• Software Memory: The ¹⁸$\text{LCP}$‘s program is stored on two removable ¹⁹$\text{EPROMs}$ (²⁰$\text{U}6$ and ²¹$\text{U}7$).²² These chips contain critical firmware and must be transferred when the physical board is replaced.²³

   

• Diagnostics: The card has a connector (²⁴$\text{KPPL}$) for an optional Programmer Module (keypad and alphanumeric display) to access local diagnostics and system settings.²⁵

   

• PCB Coating: The “G” in the part number indicates it has the Normal Style PCB coating (standard industrial protection).²⁶
