FUNCTIONAL DESCRIPTION:

DS200SLCCG2A is a LAN Communication Interface Card manufactured and designed by General Electric as part of the Mark V Series used in the GE Speedtronic Gas Turbine Control systems. The SLCC (LAN Communications Card) serves as a crucial interface between the drive or exciter and various control modules, supporting both isolated and non-isolated communication circuits. One of its notable features is a 16-character alphanumeric display, managed by the display controller U18, which provides real-time operational data, status messages, and diagnostic information. This display connects to a programmer module that physically mounts onto the SLCC and plugs into connector KPPL, allowing operators to configure parameters and monitor system functions conveniently. This user interface enhances system transparency and enables quick diagnostics and adjustments during operation or maintenance.

At the heart of the SLCC is the LAN Control Processor (LCP), U1, which manages all communication functions on the card. The LCP runs software stored in two replaceable EPROMs (U6 and U7), making firmware upgrades and troubleshooting straightforward. Its operations are supported by dedicated RAM modules (U8 and U9), ensuring fast and efficient data handling. Additionally, a dual-ported RAM (U5) provides a high-speed communication channel between the LCP and the Drive Control Processor (DCP) on the DS215SDCC Drive Control Card (SDCC) through the 3PL connector. This dual-ported RAM allows simultaneous and independent memory access by both processors, enabling smooth, real-time data exchange and system coordination essential for drive control operations.

CRAD GROUPS:

The SLCC (LAN Communications Card) is available in three distinct group versions, each designed to meet different network communication requirements within drive or exciter systems. While the group number G3 was never manufactured, the available versions — G1, G2, and G4 — provide specific combinations of communication capabilities based on the intended application. These variations allow users to choose the appropriate card based on the networking infrastructure in use, such as DLAN or ARCNET, ensuring compatibility and optimal performance.

• DS215SLCCG1A__: This version includes circuitry for both DLAN and ARCNET communication, making it the most versatile of the available group numbers. It enables the drive to communicate seamlessly across both network types, which is particularly useful in complex or mixed-network environments.

• DS215SLCCG2A__: This variant is equipped with circuitry for DLAN communication only. It is ideal for systems that operate exclusively on the DLAN protocol and do not require ARCNET connectivity, offering a more focused and potentially cost-effective solution.

• DS215SLCCG4A__: The G4 version is the most basic and does not include circuitry for either DLAN or ARCNET. This version may be used in applications where network communication is handled externally or is not required, or where the SLCC's other functionalities are sufficient without integrated LAN support.

CONFIGURABLE HARDWARE:

The SLCC (LAN Communications Card) incorporates configurable hardware jumpers that must be correctly set to ensure proper operation within the specific drive or exciter application. These jumpers are crucial for defining certain hardware behaviors or operational modes, either for factory testing purposes or to enable specific user-defined application options. Proper configuration of these jumpers helps tailor the SLCC’s functionality to the system requirements and ensures compatibility with other connected components. There are two types of jumpers on the SLCC:

• Berg-type jumpers, identified by a “JP” prefix, are small, manually movable plastic connectors that can be repositioned on pins to enable or disable specific features.
• Wire jumpers, identified by a “WJ” prefix, are fixed soldered connections used more commonly during manufacturing and factory testing.

Most of these jumper settings are preconfigured at the factory, and it is generally recommended that users do not change them unless specifically instructed. The default positions of the jumpers for each SLCC board are recorded in the test data sheets that accompany the controller and are typically stored in the drive or exciter’s door pocket. These sheets serve as a reference for verifying jumper positions during installation or troubleshooting. A detailed listing of jumper functions and their default settings is typically provided in Table 1 of the technical manual or documentation, offering clear guidance on jumper roles and configuration.

SOFTWARE:

The software for the SLCC’s LAN Control Processor (LCP) is stored in two EPROMs (U6 and U7). These EPROMs are not field-configurable, but they are removable and interchangeable between boards. When ordering a replacement SLCC board, it's important to understand that the DS200SLCC version is shipped without EPROMs—the sockets for U6 and U7 will be empty. Therefore, you must transfer the EPROMs from the original board to the new DS200SLCC to retain the existing software functionality. If you require a replacement SLCC or LCC board with the EPROMs already installed, you should specifically order the DS215SLCC version, as it includes the pre-installed EPROMs. This ensures the board is ready for immediate use without the need for manual EPROM transfer.

FREQUENTLY ASKED QUESTIONS:

What is the LAN Communications Card (SLCC)?

The LAN Communications Card (SLCC) is a key component used for communication between a drive or exciter and the control systems. It features both isolated and non-isolated circuits for communication, facilitating smooth integration between the control processor and the drive system. The card also includes a 16-position alphanumeric display for easy monitoring and troubleshooting, with a display controller connected to the programmer module.

How does the LAN Control Processor (LCP) operate in the SLCC?

The LAN Control Processor (LCP) is the primary microprocessor responsible for the operation of the SLCC. The LCP is powered by two replaceable EPROMs (U6 and U7), which store its software. Additionally, the LCP is equipped with dedicated RAM (U8 and U9) to ensure smooth operation.

What should I do if I need to replace the SLCC or the EPROMs?

If you need to replace the SLCC or the EPROMs, you must first remove the EPROMs from the old SLCC and install them into the new board. This is essential because the replacement SLCC does not come with the EPROMs pre-installed.
