Goals
4
• Existing SCADA programming standard had not been updated in 15+ years
• An update was sorely needed
• SCADA technology has improved since 2002
• ASM & EPRI Studies on SCADA Screen Effectiveness published 2008/2009
• EEMUA 201 standard on operator displays published in 2002, revised 2010
• High Performance HMI Handbook published in 2008
• ISA101 High Performance HMI standard published in 2015
• Bring in Best Practices from ISA112 SCADA System standards committee
1. Make SCADA Easier to use
2. Reduce Screen Clutter
3. Give operators information to troubleshoot problems (why did it shut down?)
4. Hide unnecessary information, with “Show Details” buttons to show more
5. Standard control interfaces for pumps, valves, instruments, and UVs
6. Make colours, symbols and terminology more consistent
7. Apply High Performance HMI Ideas (but make look/feel changes gradually)

“Missing information” for operators
Bright colours on unimportant items
Inconsistent placement/display of values

Old Screens

Confusing piping arrangements
Piping shown does not match reality. Key info missing.
Looks very “busy”. Low importance items are prominent

Fire Engine Red!
Hard to see pumps that are off.
Everything on this screen seems to be “shouting” for attention
