Description
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

system structure
The Freelance 800F process control system is divided into operator levels
and process control level. The operator level contains controls for operation and display.
Archiving and logging, trending and alarming functions. Controller executes open loop
and closed loop control function.
Freelance 800F DigiVis Operator Level
DigiVis operator stations use PC hardware, either standard commercial
Business PCs can also be industrial-grade PCs and run on Micro-
under soft Windows operating system. DigiVis supports dual-screen display operation
operating technology, that is to say, two operations can be performed using one PC
station and operate with a mouse and a
