Well suited to a harsh environment – the AC 800PEC for traction

Traction with its particularly harsh environmental conditions

is one of the most important applications of the AC 800PEC.

The controller operates through a wide temperature range

(– 40 to + 70 °C), with vibrations according to traction

standards. The compact solution is the ideal response to

the demands of restricted spaces and allows integration of

the processing unit together with all the I/Os in the same

compact hardware device.

Top reliability is a must – the AC 800PEC in power generation

Typically, excitation systems are used for generator control in

power-plants where high reliability is the No. 1 requirement.

Due to the very short process cycles, traditional redundancy

concepts are no longer applicable.

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.

AC 700F – the controller to enhance scalability

AC 700F is a process station with direct S700 I/O

modules in a small footprint.

It is suitable for very small applications from 16

to 256 I/Os and thereby widens the Freelance

800F application area ranging from very small to

midsize projects with several thousands of signals.

AC 700F provides superior functionality and

ease of use, with the option to expand the

system size. Like AC 800F, AC 700F offers

powerful engineering options and convenient

visualization capabilities.

The engineering tool is the same as for AC 800F including the advan

tage of ease-of-operation with DigiVis, pre

engineered visualization components such as

faceplates, module diagnosis, extended trouble

shooting capabilities, ready-made system com

munication, event list, alarm line, trend displays

or automatically generated sequence diagrams.

These components can be used straight out of

the box, eliminating time-consuming, manual configuration.
