Functional Description

IS200DSPX2B is a Digital Signal Processor Control Board developed by GE. It is a part of EX2100 excitation system. It serves as a controller for bridge and motor regulation, gating functions in Innovation Series drives, and generator field control in the EX2100 Excitation Control System. The board plays a crucial role in logic processing, signal handling, and interfacing functions within these systems. Equipped with a high-performance digital signal processor (DSP), memory components, and an application-specific integrated circuit (ASIC), ensures optimized signal processing and real-time control for excitation and drive applications.

Digital Signal Processor (DSP) Capabilities

The DSPX board utilizes a high-speed DSP running at 60 MHz, enabling precise real-time control. It supports four external interrupts, which are essential for efficient system operations:

• INT0: Stack Overflow Interrupt
• INT1: Inner Loop Load Pulse
• INT2 & INT3: Configurable Inputs for system-specific functions

These features ensure that the DSP can manage high-speed data processing and control multiple system functions with minimal latency.

Memory and Data Storage

Equipped with multiple types of memory to enhance its operational capabilities:

• FLASH Memory: Stores DSP boot images, code execution files, configurable items, and system history records.
• RAM: Provides temporary data storage and execution space for control functions.
• NVRAM: Used for nonvolatile storage of critical system parameters.
• Add-Only Memory: Stores board revision identification data to ensure compatibility and traceability.

These memory components allow the board to execute control operations smoothly while preserving historical data for diagnostics and maintenance.

Onboard Firmware and Configuration

The firmware on the board is stored in Flash memory and consists of three main types:

• Boot Loader: Manages the power-up sequence and is not intended for field reloading.
• Application Code: Defines the control functions specific to the drive or exciter system. This is loaded through the Tool port on the exciter.
• Configuration Parameters: Used to set up exciter and drive parameters, loaded using:
  
  • Unit Data Highway (UDH) for exciter parameters.
  • Serial Port, ISBus, or Ethernet to ACLI for drive parameters.

These firmware components ensure that the board can be customized and updated for various applications while maintaining a structured and reliable control environment.

Integration with EX2100 Excitation System

The DSP Control Board is designed for seamless integration within the EX2100 Excitation System, providing:

• Real-time signal processing and logic control for field excitation and motor regulation.
• High-speed communication with other control modules for synchronized operations.
• Flexible firmware configuration for different applications, ensuring adaptability in power generation and industrial automation systems.

Frequently Asked Questions

What is IS200DSPX2B?
It is a Digital Signal Processor Control Board developed by GE.

What are the specialized functions of the DSPX board?
The board utilizes custom logic in Field Programmable Gate Arrays (FPGA) or ASICs to handle specialized functions efficiently.

How many serial interfaces does the DSPX board have?
The board provides four serial interfaces. Two 5 Mb/s ISBus interfaces (can function as master or slave). One asynchronous TTL interface for a PC-based configuration tool. One asynchronous TTL interface for a programmer board.

What is the function of the synchronizing load pulse signals?
The inner loop load pulse Captures I/O values (bridge, motor, generator voltages, current VCOs, tachometer counters, and discrete inputs). It also synchronizes ISBus channels, software, and gating outputs. Application loop load pulse Captures values of other application VCOs and optionally the tachometers, operating at a multiple or sub-multiple of the inner loop load pulse.

How does the board synchronize with other system components?
It synchronizes I/O signals, ISBus channels, software processes, and gating outputs using load pulse signals for real-time data capture and control.
