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

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

It only takes up less cost in the whole system, then write engineering applications
The cost of software becomes increasingly important. Generally speaking, a self
The engineering application software cost of the automation project accounts for about the entire project.
About 50%, it is not difficult to see that the migration of cost structure creates a lot of innovation for users.
Create an opportunity to optimize project investment, therefore, it is necessary to start from engineering programming
Think about lowering costs in the first place!
This is what we developed the Freelance 800F system for:
Keeping hardware prices consistent with those of programmable logic controllers
In this way, cost efficiency can be improved by reducing user engineering costs.
How the Freelance 800F process control system helps users reduce
Low engineering cost?
By using a complete engineering tool (Control Builder
F) to configure the entire control system, including automation functions
function, operator interface display and logging, and configuration of the fieldbus.
equipment (PROFIBUS, FOUNDATION Fieldbus,
HART, etc.) and device parameter settings.
Automatic generation of global data between the process control station and the operator station
According to communication.
For field devices, process control stations and operator stations, a unified global database is used for the entire control system, thereby reducing
cost and time investment in establishing data communication and interactive access.
And ensure the consistency of data throughout the system.
Provide system-wide unified inspection of user applications, overriding
from process control stations, operator stations to intelligent field devices, including
Including the integrity and consistency check of the user program.
The programming language strictly complies with the international standard of IEC61131-3, and has
There are high-performance graphics editing functions:
– Function Block Diagram (FBD)
-Ladder Diagram (LD)
– Instruction List (IL)
– Sequence Control Chart (SFC)
. Structured Text (ST)
Extensive function block library, user-defined function blocks can also be added
Added to it, the macro library and graphic symbols can be customized for the user.
Blocks can create graphics and operator panels.
Any standard can be integrated by means of GSD file import
PROFIBUS-DP and PA devi and process points can be opened and closed directly in FBD or IL
