以太网作为数据通讯标准已经使用多年,并且获得了巨大的成功。今天,世界上绝大多数的办公室网络和校园网络已经接受以太网并开始使用。现在,随着以太网技术的不断发展及新特性的提供,以太网正逐步地扩展到有更多需求的工业环境应用。
对于工业用户,以太网的吸引力在于其真正的“透明性”所带来的“一网到底”的美景,以及优于现场总线的特性:
数据的快速、高效传输,使用现有的配置和诊断工具( 如Telnet, HTTP, FTP),实现远程编程、诊断和控制。目前,以太网的典型应用主要集中于“管理层”,同时也在逐渐地满足“设备层”的应用。这些应用包括通过以太网传输控制信号,比如在机器人技术中,操作快速排列的设备和SCADA 的应用。
system is divided into two levels: operation management level and process control level. At the operation management level, not only the traditional control system monitoring operation function is realized
Can (operate and display, print, trend display and alarm), and also complete system hardware diagnosis and data exchange between different systems
Yes. The process control level realizes various loop adjustments including complex control (various PID, ratio, Simith, etc.) and high-speed logic control
Control, sequence control and batch intermittent control functions.
The internal communication of the process control station (between the controller and various intelligent devices such as i/0 or field instruments) adopts the international standard field general
Line. The field controller supports various field buses such as PROFIBUS, which is the most widely used open field bus in the world
Line international standard, divided into FMS, DP and PA, DP communication rate can be as high as 12MB. Can (din/is011898 standard) bus
The biggest feature is its super robustness and data security. The system also supports MODBUS. The communication with intelligent field instruments is through
IART protocol or fieldbus (31.25kb profibuspa and FF Bus).
The system communication between the operation management level and the process control level is realized by the di ginets network (Industrial Ethernet /iee802.3 standard),
The user can select the communication transmission medium (ordinary cable or optical fiber) and network topology structure according to the actual situation of the application.
Popular PC and MS_ Wi ndows2000 has been widely used in various fields all over the world and has become the de facto standard computer platform
Set. The operating station 0s, engineer station es and data gateway GS of the industrial “system have adopted this platform, thus ensuring the
It is universal, open and easy to use, and brings great convenience for future technology upgrading and maintenance.
System engineering configuration is very convenient. The configuration language is based on ie0611313 industrial standard and provides function block diagram (FBD) and ladder diagram
(LD), instruction list (IL), sequential function diagram (SFC), structured text (st) and other graphical configuration modes. The system contains about 220 functions
The algorithm library of energy block, the basic library with more than 200 graphic symbols and
