GE DS200SNPAH1ABA SNP Protocol Interface Daughterboard

الوصف

The GE DS200SNPAH1ABA SNP Protocol Interface Daughterboard is a specialized circuit board designed to enable serial communication between GE’s high-performance drive control systems and older Programmable Logic Controllers (PLCs).

It is a key component for integration in specific industrial control systems.

Function and Application

The primary function of the DS200SNPAH1ABA daughterboard is to provide an interface for the Series Ninety Protocol (SNP), which was the native serial communication protocol for GE Fanuc Series 90-30 PLCs.

• Host Board: It is a daughterboard that mounts onto a larger Digital Signal Processor Control (DSPC) board (such as the DS200DSPC) within a VMEbus rack.
• Purpose: It allows the sophisticated control logic on the DSPC board—often used in the GE Mark V Turbine Control System or the LS2100 Static Starter Control series—to communicate with a downstream Series 90-30 PLC.
• Protocols Supported: It enables serial data exchange using:
  • RS-232C: For shorter-distance, point-to-point communication.
  • Isolated RS-485: For more robust, longer-distance, multi-drop (bus) communication in a noisy industrial environment.

This board is essential for systems that integrate the modern turbine or drive control architecture (Mark V/LS2100) with legacy control equipment (Series 90-30 PLC) that relies on the SNP protocol.

Technical Details

Note on Compatibility:

It is important to note that this board is typically not required in newer control systems, such as Load Commutated Inverters (LCIs) that use the “Innovation Series Controller,” as those systems have integrated functionalities that eliminate the need for this specific PLC interface.
