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.

Whenever you need us, we’re there

Powerful tools and effective training

The AC 800PEC tool is used for all AC 800PEC controller

handling operations. It supports you in all project phases –

from engineering, installation and commissioning to opera

tion and maintenance. Training courses help you increase

your return on investment, reduce down time and improve

the skills and motivation of your personnel. Throughout a

product’s lifetime, ABB provides training and technical

support, and arranges service contracts – all backed by a

world-class global sales and service network.

Local presence – worldwide

With offices in some 100 countries, ABB is well placed

to offer the best technical advice and local support around

the clock. ABB’s worldwide presence is built on strong

local companies. We offer local sourcing while drawing on

our worldwide experience. By combining the experience

and know-how gained in local and global markets, we ensure

that our customers can gain the full benefit of our products.

What you simulate is what you implement

Straightforward engineering workflow

In the traditional development process, system engineers

would define the specifications, which software engineers

would then interpret – a time-consuming and error-prone

process that also reduced the likelihood that the resultant

software would correspond to the original specifications and concept.

The AC 800PEC development workflow uses MathWorks®

tools for model-based design as a single development

platform for the entire development process.

Simulink® is used to run system simulations. Real-Time

Workshop® then automatically generates and downloads

controller code from the Simulink® models to the AC 800PEC

controller, eliminating the need to translate the models

manually into C-code.

The use of Real-Time Workshop® allows interactive debug

ging of the software on the controller. Specification and code

are synchronized throughout the development process by

using Simulink® models as executable specifications.

Parameters can be changed and optimized on the PC, and

code can be generated automatically from the models and

then transferred to the controller directly via an Ethernet connection.

Precision for optimum quality – the AC 800PEC for industrial processes

The most demanding function in a rolling mill is thickness

control. By using the powerful AC 800PEC controller and its

ability to implement C-Code beside the standard IEC 61131-3

program level, a new thickness control solution for cold

rolling mills has been developed based on an MIMO (Multi

Input Multi-Output) control concept. The benefit to the

customer is an improvement in thickness deviation by up to 50 percent.

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.

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.

Versatile and reliable – the AC 800PEC adapts to any application

Seamless integration into plant control

In today’s demanding market, a controller must not only

deliver maximum performance but also provide transparency.

In this respect, the AC 800PEC provides a large range of

possibilities. Integrated communication ensures transparent,

plant-wide data exchange and control – from overall plant

control down to separate processes.

Use of ABB’s System 800xA with the powerful AC 800PEC

controller permits uniform automation throughout the plant,

seamlessly integrating advanced solutions into the process

control system. Strict security procedures and effective

firewalls prohibit unauthorized intrusions and ensure per

manent system safety.

The AC 800PEC provides connectivity, using either native

(built-in) or add-on functionality.

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.
