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 is equipped with a high-speed Digital Signal Processor (DSP) operating at 60 MHz, enabling it to handle complex real-time control tasks with high precision and responsiveness. This processing speed is crucial in applications that require rapid data acquisition and control loop execution, such as turbine control systems, industrial automation, or embedded systems. The DSP's architecture enables it to efficiently execute signal processing algorithms, manage timing-critical routines, and respond promptly to system events.
• A key feature of the DSPX board is its support for four dedicated external interrupts, which enhance the system's ability to respond to asynchronous events. These include INT0, configured as a stack overflow interrupt, providing a critical safeguard against runaway code execution or memory corruption. INT1 is designated for the Inner Loop Load Pulse, which plays a crucial role in synchronized loop control operations, helping maintain timing accuracy in control systems. INT2 and INT3 are user-configurable interrupts, offering flexibility to support a range of system-specific functions, such as custom fault detection, communication triggers, or synchronization signals.
• Together, these features allow the DSP to manage high-speed data processing and execute multiple control functions concurrently with minimal latency. The real-time interrupt handling capabilities ensure reliable performance under demanding operational conditions, making the DSPX board a robust component in advanced control and monitoring systems.

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.
