PP846 3BSE042238R1 touch screen real-time database plays the role of the central link, here for data sharing, each performance code and it exchange data, used to store the data collected on the site, control output and some accounting of the central results and control algorithm structure information. Data inspection module is used to collect on-site data and fault signals, and realize the necessary auxiliary functions such as digital filtering, unit transformation and compensation operation. DCS control function through configuration generation, different systems, the demand of the control algorithm modules are different, usually touch some of the following modules: arithmetic operation module, logic operation module, PID control module, variant PID module, manual switching module, nonlinear processing module, actuator control module and so on. The control output module mainly realizes the output of control signal for fault handling. DCS in the operation station to complete the system development, generation, testing and operation mission, which requires the corresponding system software support, the software includes the operating system, programming language and a variety of tools software. A set of perfect DCS, the application software running on the operation station should be able to achieve the following functions: real-time database, network management, historical database management, graphics management, historical data trend management, database detailed display and correction, record report generation and printing, man-machine interface control, control loop conditioning, parameter list, serial communication and a variety of configuration. DCS development process is primarily the use of system configuration software to control the actual needs of the system to generate all kinds of application software process. Configuration software functions include basic equipment configuration and application software configuration. The basic equipment configuration is to give the system a equipment information, such as the number of various stations in the system, their index symbol, the large number of points per driver station, short performance cycle and memory capacity, etc. The configuration of application software contains rich content, mainly including the following aspects. In essence, the configuration of control loop is to use all kinds of fundamental functional modules provided by the system to form a variety of actual control system. At present a variety of different DCS supply configuration methods are not the same, summed up there are operation module connection method, decision table method, process record method and so on.

但事實(shí)上，國(guó)家對(duì)這方面的要求早就很明確了。以國(guó)家電網(wǎng)為例。早在2006年，國(guó)網(wǎng)1167號(hào)文就規(guī)定了什么樣的安全產(chǎn)品可以進(jìn)入生產(chǎn)控制區(qū)，即需要國(guó)家委托評(píng)估的產(chǎn)品可以安排在生產(chǎn)區(qū)，南方電網(wǎng)2015年通用技術(shù)規(guī)范也有相關(guān)要求。更重要的是，2015年電力局36號(hào)文件出臺(tái)，提出要加強(qiáng)產(chǎn)控區(qū)主機(jī)操作系統(tǒng)建設(shè)。原來(lái)，加固只能根據(jù)用戶的需求和自身的安全意識(shí)來(lái)決定，但現(xiàn)在國(guó)家有了明確的規(guī)定。PP846 3BSE042238R1觸摸屏15年前，加強(qiáng)主機(jī)的工作相對(duì)困難，但即使在電力局36號(hào)文件頒布6年后，許多廠站主機(jī)系統(tǒng)仍未得到加強(qiáng)。面對(duì)這種情況，國(guó)外廠商也在改變方式來(lái)滿足要求。自己的系統(tǒng)PP846 3BSE042238R1觸摸屏附帶主機(jī)加固軟件。當(dāng)然，他們只是想滿足國(guó)內(nèi)文件的要求，要求我們不要變相做國(guó)內(nèi)加固。廠商的這種強(qiáng)化可以從兩個(gè)方面進(jìn)行反駁:國(guó)外廠商也在改變方式來(lái)滿足要求。自己的系統(tǒng)PP846 3BSE042238R1觸摸屏附帶主機(jī)加固軟件。當(dāng)然，他們只是想滿足國(guó)內(nèi)文件的要求，要求我們不要變相做國(guó)內(nèi)加固。廠商的這種強(qiáng)化可以從兩個(gè)方面進(jìn)行反駁:國(guó)外廠商也在改變方式來(lái)滿足要求。自己的系統(tǒng)PP846 3BSE042238R1觸摸屏附帶主機(jī)加固軟件。當(dāng)然，他們只是想滿足國(guó)內(nèi)文件的要求，要求我們不要變相做國(guó)內(nèi)加固。廠商的這種強(qiáng)化可以從兩個(gè)方面進(jìn)行反駁:

PP846 3 bse042238r1觸摸屏運(yùn)算模塊連接辦法是通過(guò)調(diào)用各種獨(dú)立的規(guī)范運(yùn)算模塊,用線條連接成多種多樣的操控回路,終主動(dòng)生成操控軟件,這是一種信息流和操控功用都很直觀的組態(tài)辦法。判定表辦法是一種樸實(shí)的填表形式，只需按照組態(tài)表格的要求，逐項(xiàng)填入內(nèi)容或回答問(wèn)題即可，這種辦法很利于用戶的組態(tài)操作。過(guò)程記入辦法是一種根據(jù)語(yǔ)言指令的編寫(xiě)辦法，編程自由度大，各種雜亂功用都可通過(guò)一些技巧實(shí)現(xiàn)，但組態(tài)效率較低。別的，由于這種組態(tài)辦法不行直觀，往往對(duì)組態(tài)工程師在技術(shù)水平和組態(tài)經(jīng)驗(yàn)有較高的要求。
