Purpose and Scope Purpose and Scope

While this document does describe
“what to do,”
it is not intended to
be a
“how to guide”
to the design of the plant policy or work
processes

Examples are provided in the Guideline book to help explain the
guidelines,
but the examples might NOT provide the best
implementation for your site

Communicate
the ASM® Consortium
recommendations
for the effective design and use of
operator graphics and field device displays

Enable
assessment of the quality
of a company’s
operator displays and console configuration
from the
perspective of their potential impact on abnormal
situation management

Guideline Development Guideline Development

Operator interface design has been an important foc us of the ASM
Consortium since its origin in 1994 •
During the NIST-funded Phase of the Consortium (1996-1998)
– Conducted site practice assessments, identifying b est practices including those
for operator graphics and display design
– Prototyped an advanced information system (AEGIS) that applied pacesetter
concepts to operator graphics

Drafted initial guidelines document in 2000, based on site practices

Conducted an Operator Graphics Workshop in Fall 2000 to identify
additional practices and solicit feedback on guidel ines •
Published document for ASM member use in 2000
– Project Team—Honeywell Labs, Consortium User Members &
workshop attendees
– Critical Review Team—ASMC User Members

Major refinements to the document in 2003, 2004, 20 07 and 2009

significantly less time
to deal
with the event and as a group,
were more
consistent in
doing so!
– An average of 10.6 minutes

6.1Use a minimum of color codes consistently
across display hierarchy levels.
Priority 1
Why?Consistent, distinguishable color codes allow operators to learn the codes and the
meaning behind them.
How it Works
The number of colors used to code categories of objects shou ld be kept to seven or
less, and be consistently applied. Seven corresponds to the number of items that
can generally be kept in short term memory (Wickens and Hol lands, 1999). The
seven color codes do not limit the coding of other inform ation separate from the
category information. For example, an unacknowledged, high alarm could be a
brighter, more saturated yellow, which is distinct from a n acknowledged high alarm
that would be a paler, less saturated yellow. These two ‘states’ of high alarms are
distinct from red color-coded emergency alarms, which are e ither more or less
saturated depending on their state of acknowledgement.
In general, color coding to indicate materials in process lines is not recommended in
normal display view because it can draw the operator’s att ention away from more
critical information. If one insists on showing lines colo red based on material they
contain, then colors should be implemented such that they can be toggled on and off
(or show this representation in a view generated by the IT system supporting the
plant).

ExampleThe example shows a very simple but effective color scheme. Gray and half-tones
are used for piping and equipment. Three priorities f or alarm – low, high, and
emergency priority – are shown in half-saturated light bl ue (acknowledge), saturated
orange-yellow (unacknowledged), and saturated red (unacknowledged), respectively.
This clear color scheme can be used consistently and will be e asily remembered. In
addition, off-normal operating conditions are also hig hlighted with a non-alarm color.
Figure 6.1. Color codes in this example include: Light blue for low-priority alarms, orange-
yellow for high-priority alarms, red for emergency-priority alarms (and pale red for
acknowledged emergency-priority alarms, magenta for off-normal operating conditions.

Display Style - Ensure that displays are not overly complex or cluttered due to the
inappropriate use of full intensity colors and graphical details
# Priority Guideline
3.1 1 Ensure that the overall style incorporates an effective use of half-intensity
colors to allow equipment and flow lines to appear as part of the display
background.
3.2 1 Ensure that the overall style uses animation effectively, where appropriate, to
communicate process-critical or safety-related activity.
3.3 1 Depict equipment without excessive detail to facilitate quick identification.
3.4 2 Minimize the complexity of equipment and control relationships, presenting
them in a single view.
3.5 2 Make detailed information, such as tag names, available if needed.

5.1 1 Ensure that the navigation scheme is fairly simple and flat.
5.2 1 Ensure good organization to allow for direct access to primary displays and
intuitive access to non-primary displays.
5.3 1 Ensure that navigation to primary displays is possible without the use of a
display menu directory.
5.4 1 Ensure the soft-key configuration follows a systematic, conceptual
organization for position layout and grouping if soft keys are used for calling
up displays.
5.5 1 Ensure that the display call-up time averages 1 second and does not exceed 3
seconds in supporting navigation to operating displays (for real-time
monitoring and control).
5.6 3 Use yoking to automate navigation to corresponding objects or information
across simultaneous views in multi-level displays.

Color – Use color to facilitate the discrimination of the most i mportant information and
conveys the information consistently throughout the contro l room work environment
# Priority Guideline
6.1 1 Use a minimum of color codes consistently across display hierarchy levels.
6.2 1 Use red and yellow for alarms only.
6.3 1 Ensure that color combinations provide acceptable and sufficient contrast.
6.4 1 Avoid color combinations that are confusing for colorblind perception.
6.5 1 Use brightness coding sparingly for salience coding.
6.6 2 Use a display background color that maximizes the overall readability without
causing unnecessary eyestrain or fatigue over time.
6.7 2 Ensure that color is a redundant, visual coding of information.
6.8 2 Ensure that color codes avoid conflicts with cultural stereotypes and industry
standards.
