尺寸的可扩展性—从小型和紧凑型到大型和

模块化的

对于任何应用程序大小,最佳硬件配置

很容易实现:处理能力可以是

与分布式逻辑I/O设备集中在一个位置,

或者智能I/O设备可以在

提高性能和缓解中心压力

加工机

三种系统体系结构提供了从小型和

紧凑型到大型和模块化系统:

契约

一个带有集成快速I/O设备的处理器模块。这

配置非常适合:

−较小的应用程序

−有限的空间应用

−智能现场设备,例如分布式子系统

应用

标准

一个处理器模块,具有独立的快速逻辑I/O

设备。此配置非常适合:

−具有中央处理功能的标准工业应用

−具有分离式快速I/O的小型应用程序

模块化

一个或多个中央处理器模块,

智能I/O和快速逻辑I/O设备。

与更高级别的工厂控制完全无故障集成

系统以及未来的扩展和重新配置

由于采用了完全模块化的体系结构,因此非常简单。任何速度的进程接口

AC 800PEC提供两种输入/输出——快速和慢速。

而快速I/O系统涵盖了读写操作

需要不到1毫秒的时间,慢速I/O系统可以覆盖速度

大于1ms。

快速I/O系统是AC 800PEC专用的,使用设备

仅通过光纤链路连接,并带来

与电气概念相比具有显著优势:

−控制器和I/O设备之间的快速通信

−高抗电磁干扰能力

−无电势连接,制作隔离变送器

淘汰的

ABB S800系统的慢速I/O模块可以

添加到任何配置中,具体取决于项目需要。


Scalability in size – from small and compact to large and

modular

For any application size, the optimum hardware configuration

is easily achieved: the processing power can either be

centralized at one location with distributed logical I/O devices,

or intelligent I/O devices can carry out specific tasks in

the field to enhance performance and relieve the central

processor.

Three system architectures provide scalability from small and

compact to large and modular systems:

Compact

One processor module with integrated, fast I/O devices. This

configuration is ideally suited for:

− Smaller applications

− Limited-space applications

− Intelligent field devices, e.g. subsystems in distributed

applications

Standard

One processor module with separate, fast logical I/O

devices. This configuration is ideally suited for:

− Standard industrial applications with central processing

− Small applications with detached, fast I/O

Modular

One or several central processor modules with separate, fast,

intelligent I/O and fast logical I/O devices.

Full and trouble-free integration into higher-level plant control

systems as well as future expansions and reconfigurations

are easy thanks to the fully modular architecture.Process interfaces for any speed

The AC 800PEC provides two kinds of I/O – fast and slow.

Whereas the fast I/O system covers read and write operations

requiring less than 1 ms, the slow I/O system covers speeds

above 1 ms.

The fast I/O system is AC 800PEC specific, using devices

connected exclusively via fiber optic links, and brings

substantial advantages compared to electric concepts:

− Fast communication between controller and I/O devices

− High immunity to electromagnetic interference

− Potential-free connections, making isolating transmitters

obsolete

The slow I/O modules from ABB’s S800 system can be

added to any configuration, depending on project needs.
