CIMPLICITY Openprocess新一代混合控制系统曾经尝试用PLC编多回路PID控制程序吗?难道您不喜欢用DCS风格的功能块进行编程吗?今天,人们可以区别PLC和DCS在实际应用中的优缺点。还可以找到消除其差别的方法,发现最佳方案。
人们习惯的认为,对于大型过程装置的操控,用DCS做控制系统是最好的选择,其特点是集成性能好且便于使用。但是DCS系统也有其不足之处:不易升级、扩展,对第三方设备不够开放。与之相反,PLC和PC易于升级、扩展和互联,但组态却比较困难。PLC多用于小型、离散的制造过程控制,及外部条件较差或高速控制等情况。传统方法是根据需要进行权衡,找出最合适的系统。或直接选择一种产品而放弃另一种产品,使得您不得不按照现成的解决方案来设定自己的需要,放弃一些想要的功能,得到一些用处不大的功能。控制器的选择决定了整个系统的结构,包括系统的各种优势和局限条件也就定下来了。
新一代系统将为您提供一个两全其美的选择,既能体现PLC的价格优势,又能实现DCS易于使用的特点,实际上,PLC软件既适用于批量控制也适用于过程操作,随着技术的发展,使得PLC程序的开发更加快捷、简单,开发成本更低。简言之,PLC的强大功能既适用于离散控制,也适用于过程控制。
GE Fanuc的CIMPLICITY Openprocess混合控制系统是基于90-30系列与90-70系列PLC,配合相应的过程控制软件所构成的系统。这就意味着不同类型的控制器可以相互配合。
一个兼有PLC与DCS优点的过程控制解决方案就产生了,该系统即非简单的是PLC系统,也非简单的DCS系统。您可以量身定做一个解决方案,而不必过多考虑注意控制器的型号。
CIMPLICITY Openprocess是一种适合于过程控制的新的解决方案。为连续控制开发策略与过程可视化提供整体解决方案。
CIMPLICITY Openprocess是一个具有完整生命周期的系统,结合了最先进的软件与硬件的优点,利用与分布式控制系统(DCS)相似的先进的控制策略与应用程序,为过程工程师提供了丰富的过程控制系统的设计、实施、编档、维护工具。

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.
How the Freelance 800F process control system helps users reduce
Low engineering cost?
