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 modular architecture of the AC 800PEC not only greatly

reduces the complexity of the overall system, but thanks to

redundant subsystems also provides increased reliability. In

the case of a problem in one subsystem, the main controller

switches over to the remaining subsystems, which are scaled

in such a way that the overall task can still be fulfilled. Should

the main controller fail, a second controller is available in

hot-standby.
