GE DS200SLCCG1 LAN Communication Card

الوصف

The GE DS200SLCCG1 is a LAN Communication Card (also referred to as an ¹$\text{LCC}$ or ²$\text{SLCC}$) designed for the GE Mark V Speedtronic Turbine Control System and associated drive/exciter systems (³$\text{SC}2000/\text{UC}200\text{V}$).⁴

Its essential role is to provide the network interface and processing required for communication within the industrial control environment.⁵

Key Features and Function

Communication Role

The ⁶$\text{DS}200\text{SLCCG1}$ is vital for data exchange in the Mark V system.⁷ It provides the circuitry for:

• Internal Network: Communication to the host drive or exciter system.⁸

   

• External Networks: The ⁹$\text{G1}$ version specifically includes circuitry to support both DLAN and ARCNET network connections, which are crucial for industrial data transfer and control commands within the plant.¹⁰

   

• Isolated/Non-Isolated Circuits: It features both isolated and non-isolated communication circuits for enhanced industrial compatibility and noise immunity.¹¹

   

Onboard Components

The card’s design facilitates its communication and diagnostic functions:

• LAN Control Processor (LCP): The primary microprocessor (¹²$\text{U}1$) dedicated to handling network communications.¹³

   

• Dual-Ported RAM (DPR): This memory is used to allow the ¹⁴$\text{LCP}$ to communicate efficiently and simultaneously with the main Drive Control Processor (¹⁵$\text{DCP}$) (often located on an ¹⁶$\text{SDCC}$ board) via a connector labeled ¹⁷$\text{3PL}$.¹⁸

   

• Program Memory: The ¹⁹$\text{LCP}$ software is stored in two replaceable ²⁰$\text{EPROMs}$ (²¹$\text{U}6$ and ²²$\text{U}7$).²³ These must typically be transferred from the old card to a replacement card.

   

• Display Interface: It includes a connector (²⁴$\text{KPPL}$) for mounting an optional Programmer Module, which features a 16-position alphanumeric display and keypad, allowing local access to error codes and diagnostic information.²⁵
