术语表
过程站:
这个术语用于描述AC800F控制器(现场控制器)和机架式控制器。一个过程站可以设计成冗余配
置和非冗余配置。
AC800F :
这个术语用于描述AC800F现场控制器这种类型的过程站。一个冗余的过程站包含了2个
AC800F控制器。
机架式过程站:
这个术语用于描述机架式类型的过程站。一个冗余的过程站包含2个机架式CPU。
这个术语用于描述一个单独的，非冗余的过程站。
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。
对于现场设备、过程控制站和操作员站
