Functional Description

DS200DENQF1ADB is an EPROM set designed and developed by GE. It is a part of Mark V control system.�The Mark V Control System is an advanced and highly sophisticated control system developed by General Electric (GE) for the operation, monitoring, and control of industrial gas and steam turbines, specifically those used in power generation and other critical applications. It is renowned for its precision, reliability, and versatility.

System Memory Components

The memory system in the Mark V control system is divided into several components:

• EPROM (Erasable Programmable Read-Only Memory): Controllers have EPROM for storing fixed memory. This memory is non-volatile and retains data even when the power is turned off. It contains critical control sequences and essential system functions.
• RAM (Random Access Memory): RAM is used for volatile memory. It provides temporary storage for data that needs to be accessed quickly. Unlike EPROM, RAM loses its data when the power is turned off or in the event of a system reset.
• EEPROM (Electrically Erasable Programmable Read-Only Memory): EEPROM is used for permanent storage of up-to-date application software. It allows for the secure storage of critical software and data. Changes to sequencing, I/O assignments, gains, and other configurations can be made from the I processor and stored in the individual controller's EEPROM. This feature enhances system flexibility and adaptability.

Control Constants and Software Changes

• The Mark V system supports the modification of control constants such as gains and offsets, even while the turbine is online, by entering a security code.
• However, changes to application software are typically reserved for offline maintenance due to their potential impact on system stability and safety.

Hard Disk in I Processor

• The I processor is equipped with a hard disk that contains a copy of all application software and display information.
• This hard disk is essential for preserving and managing the software and display elements in the system. It allows for changes to alarm messages, text on existing displays, and the creation of new displays. Additionally, I/O tag names can be added or modified, offering a high degree of customization and adaptability.

Backup Interface

• The Mark V control system includes a small backup interface located on the cabinet door.
• This interface features a liquid crystal display with two lines, each capable of displaying 40 characters. It serves as a secondary means of monitoring key control parameters and alarms and can be used to issue operator commands. Furthermore, a second backup interface can be provided for remote mounting via an RS422 connection.

Emergency Stop Functionality

• An emergency stop pushbutton is conveniently located on the cabinet door. It has a latching contact and must be turned and pulled to reset, ensuring that it is intentionally reset by operators. Loose emergency stop pushbuttons can be provided for remote mounting.
• These emergency stop pushbuttons are hard-wired in series with the trip solenoids, and the system's diagnostics closely monitor the trip circuitry. In the event of a trip condition, a separate trip is initiated within the application software, enhancing safety and system reliability.

FREQUENTLY ASKED QUESTIONS

What is DS200DENQF1ADB?
It is a Mark V EPROM Set designed and developed by GE

Can control constants such as gains and offsets be modified while the turbine is operational in the Mark V system?
Yes, the Mark V system supports the modification of control constants like gains and offsets even while the turbine is online. This is achieved by entering a security code.

Are changes to application software in the Mark V system restricted to offline maintenance?
Yes, changes to application software in the Mark V system are typically reserved for offline maintenance. This is because such changes can potentially impact system stability and safety, requiring a more controlled and offline environment for implementation.

What is the role of the hard disk in the I processor of the Mark V control system?
I processor is equipped with a hard disk that contains a copy of all application software and display information. This hard disk is essential for preserving and managing software and display elements in the system. It allows for changes to alarm messages, display text, the creation of new displays, and modifications to I/O tag names, offering high customization and adaptability.

What is the purpose of the backup interface in the Mark V control system?
The backup interface is a secondary means of monitoring key control parameters and alarms. It features a liquid crystal display and can be used to issue operator commands. Additionally, it can display information from the system. A second backup interface can be provided for remote mounting via an RS422 connection.
