Functional Description

DS200TCDAF1ACI is a Software PROM Set developed by GE. It is part of the GE Speedtronic Mark V control system. It contains system-specific configuration data such as turbine parameters, I/O mappings, and control logic essential for proper operation. Additionally, it includes boot instructions that enable the system to initialize correctly upon startup. The PROM Set also helps identify the control system’s version and ensures compatibility with associated hardware and software, making it vital for reliable and efficient system performance.

System Operator Interface

• Operator Interface I is a user-friendly workstation designed to facilitate control and monitoring of the turbine system. It typically consists of a personal computer (PC), a color monitor, a cursor positioning device (such as a mouse or trackball), a keyboard, and an optional printer for hard copy documentation. This workstation can function either as the primary operator interface or as a local maintenance terminal, depending on the plant configuration. When integrated with a Distributed Control System (DCS), all operator commands and monitoring functions may be routed through communication links, allowing Operator Interface I to act purely as a local interface for maintenance and diagnostics.
• Operators interact with the system primarily through the monitor, cursor device, and optionally the keyboard. While the keyboard is not essential for routine operations, it enhances user convenience—particularly when accessing system displays via dedicated function keys or adjusting setpoints using direct numeric input (e.g., entering 1,000 rpm) instead of manually issuing raise/lower commands.
• To ensure operational accuracy and safety, most commands—such as engaging the turning gear—require a two-step process: an initial command selection followed by a confirming 'execute' command. The system monitor is available in multiple sizes and configurations to suit various control room layouts. It can be desk-mounted, console-integrated as a drop-in unit, or freestanding, depending on operator preference and installation requirements.

FREQUENTLY ASKED QUESTIONS

What is DS200TCDAF1ACI?
It is a Software PROM Set and is part of the GE Speedtronic Mark V gas turbine control system.

What kind of operating system does the Mark V use?
The Mark V runs on a real-time, multi-tasking operating system, which enables it to handle multiple control and monitoring tasks simultaneously without delay or data loss.

How do the internal cards in a Mark V controller communicate?
Communication between the five cards inside each controller is achieved using ribbon cables with gas-tight connectors, eliminating the need for a traditional backplane and improving system reliability.
