Industrial Network Communication Processing

The DS200SLCCG3A performs LAN communication processing through its onboard LAN Control Processor (LCP). The processor manages local packet handling, communication filtering, and data transfer between the SLCC board and the associated Drive Control Processor through the 3PL interface.

The board uses dual-ported RAM to provide simultaneous memory access between the LCP and the parent SDCC control board. This architecture supports direct exchange of control and status data without requiring serial buffering through external communication devices.

The firmware architecture uses replaceable EPROM devices installed in U6 and U7 sockets. Replacement boards are supplied with empty EPROM sockets, requiring transfer of programmed EPROM devices from the existing board during field replacement operations.

Frequently Asked Questions

Q: What is the function of the DS200SLCCG3A KPPL connector?
A: The KPPL connector provides the interface for an external programmer key module. It allows access to diagnostic displays, system status codes, and configuration information through the integrated display system.

Q: Can the DS200SLCCG3A operate without transferred EPROM devices?
A: The board requires the correct firmware stored in the EPROM devices installed at U6 and U7. Replacement installation requires transferring compatible programmed EPROM devices from the original SLCC board when applicable.

Q: How is the DS200SLCCG3A configured for system operation?
A: Hardware configuration is performed through factory and application-specific settings using Berg-type jumpers (JP) and wire jumpers (WJ) located on the PCB.

Field Installation Guidelines

• Install the DS200SLCCG3A directly onto the compatible SDCC parent control board using the specified standoff mounting arrangement.
• Verify that all EPROM devices are correctly transferred and seated before system power application.
• Inspect the 3PL connector interface for proper alignment and mechanical engagement before installation.
• Maintain separation between communication wiring and high-current power conductors to reduce electrical interference.
• Ensure PCB handling procedures include ESD protection when installing or removing the communication card.
• Confirm jumper positions (JP and WJ) match the required system configuration before returning the turbine control cabinet to service.
