Freelance 800F过程控制级
在过程控制级，Freelance 800F系统可以由
许多连接I/O单元的过程控制站组成。您可以选择这
些过程站为冗余模式(CPU冗余，现场总线模块冗
余)或非冗余模式。模块化的可插拔式输入/输出模
块依照系统过程信号的类型和数量自由选择使用。
AC800F控制器通过现场总线连接远程I/O或现场设
备。
系统通讯
操作员级和过程控制级之间通信使用TCP/IP
协议系统总线(基于以太网)，您可以选择不同
的传输介质例如AUI、双绞线、光纤或同轴电缆。
Freelance OPC服务器用于连接更高-级的操作员
站(800xA) 或其他OPC客户端。Freelance控制 系
统中的实时过程值和报警可以通过OPC进行访问。
我们同时提供一个C语言编程接口嵌入到外部基于
Windows操作系统应用程序中，适用于实现用户使
用非标准OPC通信，即DMS-API 软件包。
项目数据库
所有配置的信号，变量和过程点都在Freelance
800F系统的公共数据库中进行管理。
●所有变量列表(输入，输出,内部变量)
●过程点列表(功能块)
●图形
●程序
因为数据库是系统范围的.数据只需要输入一
次，避免了多次配置可能产生的错误。
项目数据库文件可以容易的进行存档或备份。
当用户编程后，会自动建立变量和标签列表。
而且，变量和过程点都可以在FBD或IL中直接打开和
修改。
列表其他功能包括:
●项目范围内修改名称，注释,数据或模块类型
●基于特定标准的查找和显示
●交叉参考可以在使用了大量变量或过程点的系统
范围内迅速找到所需变量或过程点的程序和画

a world leading all-round comprehensive open control system launched by the automation headquarters of ABB group
It integrates the advantages of traditional DCS and PLC and supports a variety of international fieldbus standards. It has the complex analog loop regulation function of DCS
Friendly human-machine interface (HMI) and convenient engineering software, as well as high-speed logic and sequence control equivalent to high-grade PLC indicators
Braking performance. The system can connect not only conventional i/0, but also PROFIBUS, FF, can, MODBUS and other field bus devices. System tool
It has high flexibility and excellent scalability, whether it is the control of small-scale production devices or the large-scale integrated control of the whole plant, even
The industrial “system can cope with the field equipment maintenance management and cross plant production management control applications
As an important member of industrial “family, AC800F system fully embodies industrial” initiated and led by ABB in technology
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
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
