Functional Description

DS200GASCF1AEO is a General Electric Software EPROM designed and developed by GE. It is a part of the Mark V control system. Mark V Control System is a comprehensive and highly advanced control system designed to meet the specific needs of the power generation industry, particularly for gas and steam turbines. Its combination of advanced technology, fault tolerance mechanisms, and customization options makes it a crucial component in ensuring the efficient and reliable operation of these turbines, contributing to stable and uninterrupted power generation.

System Memory Features

Memory plays a crucial role in the operation and flexibility of the control system. It is distributed across various components, including individual controllers and the personal computer (PC) used for operator interaction. Here's an in-depth look at the different aspects of memory within the system:

Controller Memory

• Individual controllers are equipped with various types of memory. Electrically erasable programmable read-only memory (EPROM) is utilized for fixed memory, which stores essential and unchangeable information.
• Random access memory (RAM) is employed for volatile memory, allowing controllers to temporarily store and process data during operation.
• Electrically erasable programmable read-only memory (EEPROM) serves as permanent storage for up-to-date application software. This memory retains critical data even when the power is turned off.
• The flexibility of the system allows for changes to sequencing, I/O assignments, gains, and other parameters from the operator interface. These modifications can be saved to the individual controller's EEPROM, enabling system adjustments without interrupting operation.

Editing Sequences and Control Constants

• The operator-maintenance interface provides the capability to edit all sequencing in a ladder diagram format. This feature allows for precise customization of how the system responds to various conditions and inputs.
• Control constants, such as gains and offsets, can also be adjusted while the turbine is online. Security measures, like entering a security code, ensure that only authorized personnel can make these changes.

PC Memory

• The PC used for operator interaction and monitoring also plays a critical role in the system. Its hard disk contains a copy of all application software and display programming, providing a backup and ensuring that the system can be easily restored if necessary.
• Operators have the ability to add, modify, or remove alarm messages, allowing for customization of the system's alert notifications.
  Text for existing displays can be edited or entirely new displays can be created using the PC. This capability offers a high degree of flexibility in how data is presented and monitored.
• I/O tag names can be added or changed, both in standard 12-character lengths and in more descriptive 40-character fields. This flexibility in naming and labeling helps operators better understand and manage the system.
