Scalability in performance – you and your process define what you need
Your process defines the required performance level. Several
pre-configured software packages are available for easy and
straightforward engineering:
− DCS (Distributed Control System)
− Processing cycle times down to 1 ms
− Use of slow I/O
− Programming in Control Builder
− PLC (Programmable Logic Controller)
− Processing cycle times down to 1 ms
− Use of fast and slow I/O
− Programming in Control Builder
− PAC (Programmable Automation Controller)
− Cycle times down to 100 μs
− Use of fast and slow I/O
− Programming in MATLAB/Simulink and Control Builder
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.
