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.
