S800 I/O is a comprehensive, distributed and modular process I/O

system that communicates with parent controllers and PLCs over

industry-standard field buses. Thanks to its broad connectivity it fits

a wide range of process controllers and PLCs from ABB and others.

By permitting installation in the field, close to sensors and actuators,

S800 I/O reduces the installation cost by reducing the cost of cabling.

And thanks to features such as “hot swap” of modules, on-line

reconfiguration and redundancy options, it contributes to keeping

production – and thereby profits – up. 

Scales from low cost, standard function to high end features like hot-swap, HART, time tagging, redundancy down to I/O channel.

The new generation of HMIs has a huge impact on operator performance:

• they improve the operator’s ability to detect abnormal situations before an alarm occurs by a factor of five;

• the operator success rate in handling abnormal situations is almost 100 percent; and,

• the time it takes to correctly handle the situation is almost half that of operators working with traditional HMIs.

Besides grayscale graphics and the consistent and careful use of color, shapes and motion,

high performance graphics typically include the following features to maximize the attention and effectiveness of the operator:

• Alarm priority colors are used for alarms only

• Consistency in graphic layout to ensure operator situational awareness

• Tab-based navigation for one-click access to primary displays

• Embedded trends, which display historical data in a graphic to efficiently draw

the attention of the operator to abnormalities and deviations

• The normal operating range and high / low alarm limits are shown for

each item of equipment using an intuitive bar graph (see Figure 5)

• Bubble-up alarming allows the alarm with the highest priority to ‘bubble up’ 

above lower priority alarms associated with the same device

Importance of HMI

In control rooms of old, the number of alarms was limited by the amount of space

on the control room panel board and the cost of wiring equipment from the production area to the board.

Annunciators, indicators and switches (to acknowledge and clear a resolved alarm)

had to be essential to justify a place on the panel.

If a new alarm was needed, an existing alarm would usually have to  make way.

This began to change with digital signals and the distributed control system (DCS) in the 1980s.

Panel boards were replaced by monitors and servers,

and signals were transmitted from plant equipment to computer processors,

where the signals were turned into actionable information.

But the alarms were overloading the control room and terms such as flooding,

nuisance, chattering, fleeting and stale were coined to describe them and their effect on the operators.

The modern HMIs are equipped with high performance grayscale graphics,

using color carefully and provide effective alarm handling and analysis.

Leading paths to greater awareness, faster response and better decisions

Handling the unplanned outages has become the number-one priority for many companies today.

On an average, operators deal with thousands of alarms per day. 

Hence, they should face no more than two alarms per 10-minute period

but alarm overload distracts the operators and often causes unplanned downtime.

For maximum plant performance, high performance HMI and advanced alarm management

helps to improve the operator’s tools and work environment.

An ABB case study reveals savings of more than $800.000 from upgrading to a high performance HMI.

• Bubble-up alarming allows the alarm with the highest priority to ‘bubble up’ 

above lower priority alarms associated with the same device

• Integrated help displays in the form of pop-ups

• Extendable faceplates put all the information the operator needs in one place

• Level 1 surveillance of the entire plant or unit in one graphic to facilitate

rapid visualization of the entire process, as well as KPIs

• Level 2 visualization of specific parts of the process, providing alarms,

information and controls for each area and easy navigation to level 3 graphics (P&ID style displays)

• Alarm macros for condition-based alarming, if each alarm condition needs to be managed individually

System 800xA extends the scope of traditional control systems

to include all automation functions in a single operations and

engineering solution. The result is significant improvement in

process control as well as production management, smart

instrumentation, smart drives and motor control, information

management, asset optimization and documentation.

The Advant Master systems provide the flexibility to implement

System 800xA functionality in an incremental fashion. Others

promote ‘rip-and-replace’ migration strategies, while ABB delivers

genuine system evolution, allowing Advant Master users to build

on their strong DCS foundation. New functionality can be added

at a pace that’s tailored to user needs. 

■ Maximum return on investment

For Master DCS and Advant OCS with

Master software systems, ABB offers

evolution strategies to ensure maximum

return on investment while enhancing

equipment availability and performance.

ABB’s systems are designed to be backward compatible, protecting existing

investments in Advant Master and

ensuring cost-effective strategies for

extension and growth.

This enables Advant Master controllers,

network, I/O and field wiring to be retained

when upgrading to newer user interfaces.

Being competitive in today’s business environment requires

continuous productivity improvements. ABB has combined Advant

Master (Master DCS and Advant OCS with Master software systems)

with IndustrialIT Extended Automation System 800xA productivity

enhancement software. This provides Advant Master users with

the technology and solutions needed to achieve sustainable

competitive advantages by enabling plants to perform smarter

and better at lower costs.
