Functional Description
DS200GHDCF1CBH is a software PROM set designed and developed by GE. It is a part of the Mark V control system. EPROM stands out due to its reusability. Unlike traditional ROMs, EPROM can be erased and reprogrammed multiple times, allowing for data modifications and updates as needed. The processes within EPROM, including erasure and reprogramming, are reversible, enabling data alterations and updates.
Features
- It generally offers higher storage endurance compared to PROM. Its ability to withstand numerous erase and write cycles contributes to its prolonged lifespan.
- EPROM's construction includes a resin or fused quartz window. This feature allows ultraviolet radiation to pass through, facilitating the erasure of stored data.
- It falls under the category of Read-Only Memory that permits both reading and writing of data multiple times, setting it apart from traditional ROMs.
- In case of errors or bugs during the writing process on EPROM, the data can be reversed, enabling corrections and subsequent usage.
- Represents a modernized version of PROM, offering the ability to erase and reprogram data, a capability lacking in PROM.
- While offering erasability, is comparatively less flexible and scalable than PROM. Its reusability is balanced by certain limitations in terms of flexibility and scalability.
- Primarily constructed using MOSFET (Metal Oxide Semiconductor Field Effect Transistor) technology, forming its key electronic component.These unique features and characteristics distinguish EPROM from other types of ROMs, highlighting its advantages and specific functionalities within electronic systems requiring erasable and reprogrammable memory capabilities.
System Time synchronization
- Time synchronization is a critical aspect of coordinating operations across various systems within a plant, particularly within the Mark V control panels connected via the Stagelink. This synchronization ensures that all Mark V control panels are aligned with a global time source (GTS) for accurate timekeeping and uniformity of operations.
- The process involves linking the Mark V control panels to a GTS, which could be an IRIG-B time code signal or periodic pulse inputs. These signals serve as the primary references for timekeeping. While there might be some minimal loss of accuracy over distances or due to signal transmission, the synchronization process aims to minimize this deviation.
- The primary objective of time synchronization is to set the time clocks of all computers integrated with operator interfaces in correlation with the GTS. This ensures that these computers display and utilize time-based information accurately and consistently. As a result, operators can rely on synchronized time data for issuing commands, managing alarms, logging data, and monitoring system operation across the Mark V control panels.
- Furthermore, it's essential to extend this time synchronization beyond the Mark V control panels to encompass the entirety of the plant's equipment, including Distributed Control Systems (DCSs). Achieving this synchronization throughout the plant allows for cohesive and coordinated operations, enhancing efficiency and facilitating accurate data correlation and analysis.
- By aligning various systems and devices with a common GTS, plant operations can maintain a standardized and synchronized time reference. This synchronization serves as a fundamental basis for time-dependent processes, ensuring consistency, accuracy, and effective coordination across the entire plant infrastructure.
