GE DS200SLCCG1ADC LAN Communication Card

الوصف

The GE DS200SLCCG1ADC is a further revision of the LAN Communication Card (¹$\text{SLCC}$), which is an essential board for industrial networking within the GE Mark V Speedtronic Turbine Control System.²

Its primary role is to manage and facilitate the communication of control data, commands, and diagnostics between the main control processor and other network components across the plant.

Key Technical Specifications

The $\text{DS}200\text{SLCCG1ADC}$ inherits the core functionality of the $\text{SLCC}$ family, with specific revision updates:

• Communication Protocols: This G1 variant provides the hardware and circuitry necessary to support both DLAN (Drive LAN) and ARCNET communication standards, which are integral to the Mark V control architecture for reliable, high-speed data exchange.³

   

• Dedicated Processing: It utilizes a LAN Control Processor (⁴$\text{LCP}$) to dedicate processing power specifically to network functions, thereby minimizing the load on the main turbine control processor (⁵$\text{DCP}$).⁶

   

• Data Interface: High-speed data exchange between the $\text{LCP}$ and the main control processor is accomplished using Dual-Ported RAM ($\text{DPR}$).
• Diagnostics: The card includes a connector (⁷$\text{KPPL}$) for attaching a Programmer Module (keypad and alphanumeric display).⁸ This enables local access for technicians to view and configure system diagnostics and parameters.

   

• Software: The $\text{LCP}$‘s operating firmware is stored on two removable $\text{EPROMs}$ ($\text{U}6$ and $\text{U}7$). These chips are critical and must be carefully transferred from a faulty board to its replacement.
• Physical Style: The “G” designation confirms that the board uses the Normal Style PCB coating (standard industrial protection).
