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
Harsh industrial environment. The equipment can be installed in the cabinet or on the wall. The system complies with all current EMC standards and has CE standards
Annals.
Industrial “DCS system design purpose: the most economical engineering investment and the most powerful control function.
Industria1 “five features of DCS system:
1、 The comprehensive control system integrates DCS & PLC & field bus;
2、 RISC superscalar high-speed CPU with super performance;
3. High reliability, strict industrial application practice, and application performance of more than 1000 sets in China;
4、 Good openness, flexibility and expansibility;
5、 Easy engineering, friendly interface and simple maintenance;
2. Industria1 “system communication
Industrial ial “the system uses the international standard industrial bus. The field controller supports PROFIBUS, FF, MODBUS, can and other countries
International standard fieldbus, PROFIBUS is the most widely used open fieldbus international standard in the world, which is divided into FMS, DP and pa
Level III, DP communication rate can be up to 12MB. PROFIBUS is used to connect distributed i/0 stations, field bus instruments and other intelligent devices.
The communication among process station, operator station and engineer station is realized through the system bus diginets (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin cable, thick cable or optical fiber cable and mixed media) and network topology can be selected for the system bus
Due to the adoption of tcp/ip protocol, the system can also realize ultra long distance communication with the help of public telephone network (dial-up mode) or satellite.
PLC and other subsystems communicate with industrial “system through Modbus protocol interface. The system also supports iec870-5 over control coordination
Discussion.
The flash EPROM inside PS provides more than 220 function modules (control algorithm subroutines), in addition to the base specified in IEC 61131 3 standard
In addition to this content, many powerful and strictly tested function blocks from practical engineering applications are also expanded. Any complex control
All schemes can be realized by the combination of these function blocks.
The function blocks provided by the system mainly fall into the following categories:
o
Analog quantity processing
o
Digital quantity processing
Loop adjustment
Logical sequence control
c
Logical operation
Monitoring function
Acquisition function
c
Arithmetic operation
c
Tcp/ip protocol communication interface
Modbus protocol communication interface

4.2 field controller PS
Industrial ial “field controller PS is a special process control station, which is embedded with a fieldbus communication interface for users to use
Fieldbus technology provides a very flexible choice. Each PS is allowed to insert 4 fieldbus interface cards (card types can be different),
Each card is connected to a fieldbus to collect process data and diagnostic information from the bus. The interface card is easy to replace and plug and play
(plug & play) and can be plugged in and out with
