FUNCTIONAL DESCRIPTION:

DS200SLCCG2A is a LAN Communication Card manufactured and designed by General Electric as part of the Mark V Series used in the GE Speedtronic Gas Turbine Control systems. The Card (SLCC) integrates both isolated and non-isolated circuits for communication with the drive or exciter. It includes a 16-position alphanumeric display and its controller (U18), which interfaces with the programmer module. This module attaches to the SLCC and connects via the KPPL connector. The primary microprocessor, the LAN Control Processor (LCP) located at U1, runs the software stored in two removable EPROMs (U6 and U7). The LCP's dedicated RAM is provided by U8 and U9, while the dual-ported RAM (U5) facilitates communication between the LCP and the Drive Control Processor (DCP) on the DS215SDCC Drive Control Card (SDCC) through the 3PL connector. Dual-ported RAM (DPR) is a type of memory that can be accessed simultaneously by two processors.

CRAD GROUPS:

There are currently three group numbers of the SLCC available (G3 versions were never manufactured). The variations between the groups are as follows:

• DS215SLCCG1A_ _: Includes the circuitry used to connect the drive to both DLAN and ARCNET networks
• DS215SLCCG2A_ _: Includes the circuitry used to connect the drive to DLAN networks only
• DS215SLCCG4A_ _: Does not include either DLAN or ARCNET circuitry

CONFIGURABLE HARDWARE:

The SLCC includes configurable hardware that must be set correctly for the application:

• Berg-type (manually movable) hardware jumpers, identified by a JP nomenclature
• Wire jumpers, identified by a WJ nomenclature

These jumpers are used for factory tests or user application options. Most of the jumper selections have been factory-set. The test data sheets supplied with each controller (in the drive/exciter door pocket) indicate these factory-set positions. Table 1 lists the jumper descriptions, showing the default setting first.

SOFTWARE:

The software for the SLCC’s LAN Control Processor (LCP) is stored in EPROMs U6 and U7, which cannot be configured on-site. These EPROMs are replaceable and can be transferred between boards. When ordering a replacement board, it is important to note that the DS200SLCC does not come with these EPROMs pre-installed, as the sockets will be empty. The EPROMs from the old board must be transferred to the new one. If an SLCC or LCC replacement is needed with the EPROMs included, be sure to request a DS215SLCC as the replacement.

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.
