Hardware Features

  • Hardware Jumpers or Switches: Supported ARCNET controller boards feature hardware jumpers or switches that allow for hardware configuration. These jumpers or switches provide a convenient way to configure various settings on the board. They enable users to customize parameters such as the dual-ported memory base address, I/O base address, ARCNET address of the PC, and interrupt request level (IRQ). These hardware configuration options ensure compatibility and optimal performance of the ARCNET controller board.
  • Dual-Ported Memory Base Address: The ARCNET controller board supports the configuration of the dual-ported memory base address. This address defines the memory location that can be accessed by both the host processor and external devices. By setting the appropriate base address using hardware jumpers or switches, the board can establish a communication pathway between the host processor and connected devices, enabling efficient data transfer.
  • I/O Base Address: The I/O base address is another configurable parameter available on supported ARCNET controller boards. It determines the memory location used for input and output operations between the board and other peripheral devices. By setting the I/O base address using hardware jumpers or switches, the board can establish the necessary communication channels to interact with external devices effectively.
  • ARCNET Address of the PC: The ARCNET address of the PC refers to the unique identifier assigned to the PC when it is connected to an ARCNET network. Supported ARCNET controller boards allow for the configuration of this address through hardware settings. By assigning a specific ARCNET address to the PC using hardware jumpers or switches, the board can establish its identity on the network, enabling seamless communication and data exchange.
  • Interrupt Request Level (IRQ): The interrupt request level, or IRQ, is a crucial parameter for managing interrupt-driven communication between devices. Supported ARCNET controller boards provide the ability to configure the IRQ setting through hardware jumpers or switches. By selecting the appropriate IRQ level, the board can efficiently handle and respond to interrupts generated by connected devices or the host processor.
  • Card-Specific Features: Each ARCNET controller board may have additional features specific to the particular card model or design. These card-specific features enhance the functionality and performance of the board, catering to specific application requirements. These features may include specialized connectors, onboard components, or unique functionalities that differentiate the board from others in the product line.
  • IDP CARD Diskette: The IDP CARD diskette contains configuration information specifically tailored to the supported I/O cards. This diskette is provided with every I processor and replacement I/O card purchased from GE. The README.TXT file included in the IDP CARD diskette provides valuable documentation on the supported I/O cards and refers to the card-specific hardware setup. This information assists users in configuring and setting up their I/O cards correctly, ensuring compatibility and optimal performance.

System Memory

  • Memory is housed in individual controllers as well as the processor. EPROM is used for fixed memory, RAM is used for volatile memory, and EEPROM is used for permanent storage of up-to-date application software.
  • Changes to sequencing, I/O assignments, gains, and so on can be made and saved in the EEPROM of each individual controller. By entering a security code, changes to control constants such as gains and offsets can be made while the turbine is running. Changes to application software, on the other hand, are limited to off-line maintenance.
  • The hard disk contains a duplicate of all application software and display data. Alarm messages can be added or modified. Existing displays' text can be changed, and new displays can be created. The names of I/O tags can be added or changed.

System Features

  • Turbine Control Systems have been manufactured for several decades and are widely used in both new unit and retrofit applications. The Mark V is the most recent in a line of microprocessor-based turbine control systems designed specifically for turbine control.
  • The system is suitable for medium and large steam turbines, heavy duty gas turbines (single or dual shaft), and aircraft derivative gas turbines. The Mark V is used to control and protect the unit, along with sensors and devices mounted on the unit and its auxiliaries. The use of redundant sensors and devices for feedback, control, and protection of critical functions improves unit reliability.
  • If one of the redundant devices fails, the operation is unaffected. The connection of redundant devices to the control panel, as well as their regulation by the control software, were deemed critical factors in the design of the Mark V. This fail-safe approach results in a highly reliable turbine control and protection system.
  • The control system further improves unit reliability in its most common configuration by employing three redundant control processors. This triple modular redundant (TMR) design can safely operate, control, and protect a unit in the event that one of its control processors or control processor components fails. The TMR design allows for the shutdown and repair of a single control processor without shutting down the turbine.
