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.
