GE DS200SLCCG1ACC LAN Communication Card

الوصف

The GE DS200SLCCG1ACC is a specific revision of the LAN Communication Card (¹$\text{SLCC}$), a crucial component for network connectivity within the GE Mark V Speedtronic Turbine Control System.²

Its core function is to provide the dedicated processing and interface necessary for the drive or exciter controller to communicate over industrial networks, supporting essential plant-wide data exchange.³

Key Features and Technical Role

• Networking Capability: As a G1 variant, the ⁴$\text{DS}200\text{SLCCG1ACC}$ is equipped to handle communications using both GE’s proprietary DLAN (Drive LAN) and ARCNET network protocols.⁵ This is vital for transferring control commands, operational parameters, and diagnostic data.⁶

   

• Dedicated Processor: The card features a dedicated LAN Control Processor (⁷$\text{LCP}$).⁸ The $\text{LCP}$ is responsible for managing the network interface, handling the flow of communication data, and offloading this task from the main control processor.

   

• Inter-Processor Communication: It uses high-speed Dual-Ported RAM (⁹$\text{DPR}$) to enable simultaneous and efficient data exchange between the ¹⁰$\text{LCP}$ and the main Drive Control Processor (¹¹$\text{DCP}$) (typically on a separate board like the ¹²$\text{SDCC}$).¹³

   

• Diagnostics and Interface: The board includes a connector (¹⁴$\text{KPPL}$) for connecting an optional Programmer Module (which usually contains a keypad and a 16-character alphanumeric display).¹⁵ This allows local personnel to access diagnostics, review error codes, and configure the system.

   

• Software Storage: The operating firmware for the ¹⁶$\text{LCP}$ is stored on two removable EPROMs (¹⁷$\text{U}6$ and ¹⁸$\text{U}7$).¹⁹ These chips often contain application-specific code and must be transferred when the card is replaced.

   

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