ABB Compact control system replaces PLCs using AC 700F

Compact control system replaces PLCs

Comfortable, more efficient integration of package units

using AC 700F

The AC 700F controller increases the scalability of the

compact control system Freelance 800F towards very

small applications  with only a few I/Os and closes the

gap between PLCs (programmable logic controllers)

and complex process control systems. It is suitable

for smallest applications with about 10 to 250 I/Os per

controller and thus opens up additional application areas

for the Freelance 800F control system, which is suitable

for both small and also medium-sized projects with sev

eral thousand signals. Comfortable, advanced functions

of control systems are now also available for very small

applications – and all at a very reasonable price. The

AC 700F controller offers a large number of advantages

compared to a standard PLC with visualization from third

party vendors. The projects on the following pages show

these advantages and the various application areas for

the AC 700F controller.

Thanks to the compact control system Freelance 800F and its

AC 700F controller it is now possible for smaller automation

solutions, which to date have been dominated by PLCs, to

benefit from the advantages of process control  systems,

particularly in the process industry. There is a wide range of

use in many industries including chemicals, petrochemicals,

oil and gas, metals, cement production, glass production, etc.

The AC 700F controller can be integrated into existing Freelance

800F systems in the same way as the AC 800F controller.

In contrast to PLCs, the AC 700F controller offers all of the

advantages of the compact control system. Important for

engineering and maintenance: A single engineering tool for

all tasks: Control Builder F.

DigiVis, the visualization tool, makes operation easy, structured

and intuitive. Pre-engineered components such as faceplates,

module diagnostics, event lists, the alarm line, trend displays

and automatically generated SFC (Sequential Function Chart)

displays play a key role in this regard. The use of predefined,

field proven libraries including faceplates significantly eases

the transparency, readability and adaptability of the application

and substantially increases security. The advanced diagnostic

options and improved alarm handling allows cost cutting in

the operation and maintenance phase and asset availability

can be enhanced. This substantially increases the economic

efficiency of the entire plant
