Information technology) a new trend.
The 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 the extended library with a large number of 3D symbols.
The system uses the same set of configuration tool software to complete the configuration and commissioning of process level, operation level and even fieldbus instruments, and uses the same
A global database.
The system scale has strong scalability. The single system supports 1 to 100 control stations and 100 operation stations at most. Each control
The station can support thousands of i/0 points at most, and the scale of the whole system can be expanded. The hardware of the system control station is all metal enclosure, which can withstand the most
