对于现场设备、过程控制站和操作员站,整个控制系统采用了一个统一的全局数据库,从而降低
了建立数据通信及交互访问的成本和时间投资.
并保证整个系统范围内数据的一致性。
●提供系统全局范围的用户应用程序统一检查,覆
盖过程控制站、操作员站到智能的现场设备,包
括对用户程序的完整性和一致性检测。
●编程语言严格遵守IEC61131-3的国际标准,并具
有高性能的图形编辑功能:
-功能块图(FBD)
-梯形图(LD)
-指令表(IL)
-顺控图(SFC)
. 结构文本(ST)
●宽泛的功能块库,用户自定义的功能块也可以添
加到其中,宏库和图形符号可以为用户自定义功
能块建立图形和操作面板。
●可以通过GSD文件导入的方式来集成任何标准
PROFIBUS-DP和PA设备,并通过用户自定义对
话框形式来设计对这些设备组态配置的窗口。
●可以通过FDT/DTM技术来集成PROFIBUS现场总
线设备
系统结构
Freelance 800F过程 控制系统分为了操作员级
和过程控制级。操作员级包含了用于操作和显示.
归档和记录、趋势及报警等功能。控制器执行开环
和闭环回路控制功能。
Freelance 800F DigiVis操作员级
DigiVis操作员站使用PC硬件,既可以是标准商
务用PC机也可以采用工业级PC机,并运行在Micro-
soft Windows操作系统下。DigiVis支持双屏 显示操
作技术,也就是说使用一台PC机可以实现两个操作
员站,并用一个鼠标和一个键盘操作。
操作员级可以安装一个工程师站和几个操作员
站。ControlBuilderF工程师站对系统进行组态和调
式。通常,我们可以使用便携设备例如笔记本,实
现在办公室和现场对系统进行组态。操作员级PC机
也可以当作工程师站。工程师站在系统正常运行期
间可以关闭无需永久与系统连接。
Freelance 800F过程控制级
在过程控制级
the Freelance 800F system can be controlled by
It consists of a number of process control stations connected to I/O units. you can choose this
Some process stations are in redundant mode (CPU redundancy, fieldbus module redundancy
redundant) or non-redundant mode. Modular pluggable input/output modules
Blocks are freely selected and used according to the type and number of system process signals.
AC800F controller connects remote I/O or field device via fieldbus
ready.
system communication
Communication between operator level and process control level using TCP/IP
Protocol system bus (based on Ethernet), you can choose different
transmission medium such as AUI, twisted pair, fiber optic or coaxial cable.
Freelance OPC server for connecting to higher-level operators
station (800xA) or other OPC client. Freelance Control System
Real-time process values and alarms in the system can be accessed via OPC.
We also provide a C language programming interface to embed external
In Windows operating system applications, it is suitable for implementing user
Communicate with non-standard OPC, ie DMS-API software package.
Project database
All configured signals, variables and process points are in Freelance
800F system’s public database for management.
List of all variables (input, output, internal variables)
Process point list (function block)

Program
Because the database is system-wide. The data only needs to enter a
times, to avoid possible errors caused by multiple configurations.
Project database files can be easily archived or backed up.
When programmed by the user, a list of variables and labels is automatically created.
Moreover, both variables and process points can be opened and closed directly in FBD or IL
Revise.
List other features include:
Project-wide modification of names, comments, data or module types
Search and display based on specific criteria
Cross reference can be used in systems that use a large number of variables or process points
Programs and drawings to quickly find the desired variable or process point within the scope
