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.?
