PACSystemsTM可编程自动化控制器概述
· PLC与PAC系统的区别？
这两者之间最基本的不同是它们的基础不同，PLC的性能是基于特有硬件并且不能在PLC之间轻易的迁移；而PAC的功能是基于它的轻便控制引擎。每一个带有这种位于用户运行系统上面的引擎的应用接口，只需要很少的改变就可以在系统之间迁移。既然这个引擎同硬件分离并使用一种通用的运行系统，平台就可以根据用户的需要迅速的扩展和变化。
从应用的观点看，传统的PLC在独立元件控制方面表现良好，但在其它领域却表现不佳，用户可以通过PAC的单一平台开发和实施具有同等敏捷性和可靠性的独立的、过程和动作控制应用方案。而且，PLC基于专有技术建立，PAC广泛使用了COTS（商品现货供应）产品和技术，这样：
·有助于确保系统的可靠性和可用性，因为可以保证硬件和软件的迅速和方便的维护：
·降低了系统价格和减少了停机时间，因为随时可以得到现货。
·提高了开放性、灵活性和可扩展性。
·GE Fanuc自动化率先推出的PACSystems，现在，一种叫做可编程自动化控制器(PAC)的新型控制系统，在灵活性、开放性和鏊体性能上有了显著的提高。PAC使得用户系统在性能上有了一个越升而不用重新设计。PAC最明显的特征是一个位于运行系统上面的轻便控制引擎，它确保用户首先可以最大化他们的应用收益，其次还可以充分利用他们的自动化平台。
为满足整个工业范围内PAC平台的需要，GE Fanuc的革命性新产品PACSystems系列是一个能够提供性能越升但却不会带来移植和转换负担的控制器环境。PACSystems具有一个单控制引擎和通用的编程环境，同时也体现了通过多重化硬件平台发布可选控制方案真正集成的灵活性
Glossary
Process station:
This term is used to describe AC800F controllers (field controllers) and rack-mounted controllers. A process station can be designed to be redundant
configuration and non-redundant configuration.
AC800F :
This term is used to describe the AC800F Field Controller type of process station. A redundant process station consists of 2
AC800F controller.
Rack mounted process station:
This term is used to describe a rack-mounted type of process station. A redundant process station contains 2 rack-mounted CPUs.
This term is used to describe a single, non-redundant process station.
In the investment of modern automation system, due to the hardware equipment department
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.
