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.
但事实上,国家对这方面的要求早就很明确了。以国家电网为例。早在2006年,国网1167号文就规定了什么样的安全产品可以进入生产控制区,即需要国家委托评估的产品可以安排在生产区,南方电网2015年通用技术规范也有相关要求。更重要的是,2015年电力局36号文件出台,提出要加强产控区主机操作系统建设。原来,加固只能根据用户的需求和自身的安全意识来决定,但现在国家有了明确的规定。PP846 3BSE042238R1触摸屏15年前,加强主机的工作相对困难,但即使在电力局36号文件颁布6年后,许多厂站主机系统仍未得到加强。面对这种情况,国外厂商也在改变方式来满足要求。自己的系统PP846 3BSE042238R1触摸屏附带主机加固软件。当然,他们只是想满足国内文件的要求,要求我们不要变相做国内加固。厂商的这种强化可以从两个方面进行反驳:国外厂商也在改变方式来满足要求。自己的系统PP846 3BSE042238R1触摸屏附带主机加固软件。当然,他们只是想满足国内文件的要求,要求我们不要变相做国内加固。厂商的这种强化可以从两个方面进行反驳:国外厂商也在改变方式来满足要求。自己的系统PP846 3BSE042238R1触摸屏附带主机加固软件。当然,他们只是想满足国内文件的要求,要求我们不要变相做国内加固。厂商的这种强化可以从两个方面进行反驳:
PP846 3 bse042238r1触摸屏运算模块连接办法是通过调用各种独立的规范运算模块,用线条连接成多种多样的操控回路,终主动生成操控软件,这是一种信息流和操控功用都很直观的组态办法。判定表办法是一种朴实的填表形式,只需按照组态表格的要求,逐项填入内容或回答问题即可,这种办法很利于用户的组态操作。过程记入办法是一种根据语言指令的编写办法,编程自由度大,各种杂乱功用都可通过一些技巧实现,但组态效率较低。别的,由于这种组态办法不行直观,往往对组态工程师在技术水平和组态经验有较高的要求。
实时数据库生成PP846 3 bse042238r1触摸屏实时数据库是DCS根本的信息资源,这些实时数据由实时数据库存储和办理。在DCS中,建立和修正实时数据库记载的办法有多种,常用的办法是用通用数据库工具软件生成数据库文件,体系直接使用这种数据格局进行办理或采用某种办法将生成的数据文件转换为DCS所要求的格局。
