控制策略自动化功能组态方式
控制鐐略组态方法功能块圜(FBD)
功能块图(FBD)是- -种图形化组态编程语言,用于实现回路调节
控制和逻辑控制功能。FBD 程序是由若干功能块图有机排列而成,
各种功能、功能块及程序输入输出变量之间用信号流向线按照控制
逻辑进行连接。控制某过程所需的信号处理由FED程序完成。由于具备CAD功能,因此可以在图形工
作区轻松实现各功能和功能块的定位及连接。FBD 编辑器的输入输出区用来键入输入输出变量,输入
在左,输出在右,信号流向由左至右。
system, integrating DCS & PLC & Field Bus;
2. Using RISC SuperScalar high-speed CPU, with super performance;
Three high reliability, strict industrial application practice, more than 1000 sets of application performance in China;
4. It has good openness, flexibility and scalability;
Fifth, the project is easy, the interface is friendly, and the maintenance is simple;
2. Industria1″ system communication
Industrial” system uses international standard industrial bus. Field controller supports Profibus, FF, ModBus, Can, etc.
International standard fieldbus, Profibus is the most widely used open fieldbus international standard in the world, divided into FMS, DP and PA
Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments.
