DSQC639 ABB 可編程控制器模塊計(jì)算機(jī)系統(tǒng)由**“硬件”和“軟件”兩部分組成**
硬件是指看得見摸得著的各種電子元器件。如主機(jī)、鍵盤、鼠標(biāo)等軟件看不見摸不著，但在邏輯上，我們確實(shí)可以感知到它的存在，它由人們事先編制的具有某種功能的程席組成、比如操作系統(tǒng)、編程語言等。計(jì)算機(jī)的軟件通常又分為: 系統(tǒng)軟件和應(yīng)用軟件。
系統(tǒng)軟件:又稱為系統(tǒng)程序，主要用來管理整個(gè)計(jì)算機(jī)系統(tǒng)，監(jiān)視服務(wù)，使系統(tǒng)資源得到合理調(diào)度，它包括:操作系統(tǒng)、語言處理程序、數(shù)據(jù)庫管理系統(tǒng)、網(wǎng)絡(luò)軟件、服務(wù)程序等
計(jì)算機(jī)的種類很多，從不同的角度看，有不同的分類。
按照計(jì)算機(jī)的處理信息的方式，可以分為數(shù)寧計(jì)算機(jī)和模擬計(jì)算機(jī)。數(shù)字計(jì)算機(jī):通過信號(hào)的兩種不同狀態(tài)(1 和 )來表示信息，可以方便地對(duì)數(shù)字信號(hào)進(jìn)行算術(shù)和邏運(yùn)算，具有速度快、精度高、便于存儲(chǔ)等優(yōu)點(diǎn)。通常講的計(jì)算機(jī)一般是指數(shù)字計(jì)算機(jī)。

DSQC639 ABB 可編程控制器模塊一般只能處理模擬信號(hào)，如連續(xù)變化地電壓、電流和溫度等。這類計(jì)算機(jī)應(yīng)用鄰域有限，通用性不強(qiáng).按照計(jì)算機(jī)通用性地差異，計(jì)算機(jī)可以分為專用計(jì)算機(jī)和通用計(jì)算機(jī)。專用計(jì)算機(jī)，專門為某一問題而設(shè)計(jì)的計(jì)算機(jī)。功能較單一，對(duì)應(yīng)用環(huán)境地適應(yīng)性很差，例如計(jì)算導(dǎo)彈彈道的專用計(jì)算機(jī)通用計(jì)算機(jī):各行業(yè)和各種環(huán)境都能使用的計(jì)算機(jī)，一般具有較高的運(yùn)算速度、較大的內(nèi)存容量，我們平常使用的個(gè)人臺(tái)式計(jì)算機(jī)都屬于通用計(jì)算機(jī)
DSQC639 ABB 可編程控制器模塊該版本的亮點(diǎn)包括： 提高操作員效率：系統(tǒng) 800xA 5.1 包括高級(jí)警報(bào)管理功能，可幫助用戶實(shí)施成功的警報(bào)管理策略，并為操作人員提供更好的控制室和其他操作位置之間的職責(zé)控制。新的警報(bào)擱置和警報(bào)分析功能已添加到已經(jīng)很長(zhǎng)的警報(bào)管理功能列表中，以幫助控制警報(bào)。新版本還包括一個(gè)新的控制點(diǎn)功能，可在關(guān)鍵時(shí)期（例如換班）改善操作員的協(xié)調(diào)，從而提供更安全 的操作環(huán)境。改進(jìn)的工程和變更管理：新版本的 800xA 系統(tǒng)包括多項(xiàng)工程改進(jìn)，例如在設(shè)計(jì) FOUNDATION Fieldbus 項(xiàng)目時(shí)簡(jiǎn)化批量數(shù)據(jù)處理，以及新的和改進(jìn)的批處理程序編輯器。此外，兩項(xiàng)新功能改進(jìn)并簡(jiǎn)化了變更管理程序。任務(wù)分析工具讓用戶可以根據(jù)下載前分配的當(dāng)前任務(wù)速率評(píng)估他/她的應(yīng)用程序?qū)?zhí)行。詳細(xì)差異報(bào)告提供了一種輕松查看在控制應(yīng)用程序和圖形中所做的更改的方法，并在易于閱讀的用戶界面中提供了一份確切的修改、添加或刪除內(nèi)容的報(bào)告。

The DSQC639 ABB Programmable Controller module computer system consists of two parts ** “hardware” and “software” **
Hardware refers to the various electronic components that can be seen and touched. Such as the host, keyboard, mouse and other software can not be seen or touched, but logically, we can indeed perceive its existence, it is composed of people in advance to have a certain function of the program, such as operating system, programming language and so on. Computer software is usually divided into system software and application software.
System software: also known as system program, mainly used to manage the entire computer system, monitor services, so that system resources are reasonably scheduled, it includes: operating system, language processing program, database management system, network software, service program, etc
There are many kinds of computers, and from different perspectives, there are different classifications.
According to the way computers process information, they can be divided into digital computers and analog computers. Digital computer: through the signal of two different states (1 and) to represent the information, can be convenient for digital signal arithmetic and logic operations, with high speed, high precision, easy to store and other advantages. Generally speaking, the computer is generally an exponential computer.
The DSQC639 ABB programmable controller module can generally only handle analog signals, such as continuously varying ground voltage, current and temperature. The application area of this kind of computer is limited, and the universality is not strong. According to the differences in the universality of computers, computers can be divided into special purpose computers and general purpose computers. Special purpose computer: a computer designed specifically for a particular problem. The function is relatively single, and the adaptability to the application environment is very poor, such as the special computer to calculate the missile trajectory General computer: the computer that can be used in various industries and various environments, generally has a high computing speed and a large memory capacity, and the personal desktop computer that we usually use belongs to the general computer
DSQC639 ABB Programmable Controller Module Highlights of this release include: Improved Operator efficiency: System 800xA 5.1 includes advanced alarm management capabilities that help users implement successful alarm management strategies and provide operators with better control of responsibilities between the control room and other operating locations. New alert shelving and alert analysis features have been added to the already long list of alert management features to help control alerts. The new version also includes a new control point feature that improves operator coordination during critical periods, such as shift changes, providing a safer operating environment. Improved engineering and change management: The new version of the 800xA system includes several engineering improvements, such as simplified batch data processing when designing FOUNDATION Fieldbus projects, and a new and improved batch program editor. In addition, two new features improve and simplify the change management process. The task analysis tool allows the user to evaluate what his/her application will perform based on the current task rate assigned before downloading. The Detailed Difference report provides an easy way to see the changes made in the control application and graphics, and provides an exact report of what was modified, added, or removed in an easy-to-read user interface.
