Description
在现代自动化系统投资中,由于硬件设备部
分只占用整个系统中较少的成本,则编写工程应用
软件的成本就变得越来越重要。通常来讲,一个自
动化项目的工程应用软件费用约占到了整个项目的
50%左右,这不难看出,成本结构的迁移给用户创
造了优化项目投资的机会,所以,必须从工程编程
一开始就要考虑降低费用!
这就是我们开发Freelance 800F系统的目的:
保持硬件价格与那些可编程逻辑控制器一致的情况
下,通过减少用户工程费用来提高成本效率。
Freelance 800F过 程控制系统如何帮助用户减
少工程费用?
●通过使用一个完整的工程工具(Control Builder
F)来配置组态整个控制系统,包括自动化功
能、操作员界面显示和记录,以及组态现场总线.
设备(PROFIBUS, FOUNDATION Fieldbus ,
HART等等)和设备参数设定。
●在过程控制站和操作员站之间自动生成全局的数
据通信。
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 devices, and through user-defined pairing
dialog box to design the configuration window for these devices.
●Profibus field controller can be integrated through FDT/DTM technology
line equipment
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 keyboard.
Operator level can install one engineering station and several operators
stand. ControlBuilderF engineering station configures and adjusts the system
Mode. Usually, we can use portable devices such as notebooks to
