These make your new controllers able

to use ABB’s new S800 I⁄O system and

easily able to communicate, with other

external controllers, with ABB’s variable

speed motor drives and with smart

motor-control centers.

• More backup redundancy available,e.g.:

– Smarter solution to CPU redundancy,

eliminating critical, common, components,

– Full dual redundancy, covering,

media and communication in interfaces,

for S100 I/O and Advant Fieldbus 100.

• A self-tuning, adaptive process controller

(AC 450) that makes short work out

of setting up control loops accurately

and responsively, even in difficult applications.

• Fuzzy logic control, a control method

based on degrees of truths as opposed

to conventional binary logic that only

recognizes two states: true or false.

A control strategy that is often able to

untangle elegantly control problems

that are difficult to solve in other ways.

• Windows NT-based engineering tool,

You save money; StepUp includes:

• attractive prices on controller cabinets

with all the hardware and software required.
