HMI screen layout principles in SCADA systems - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main goal of an HMI screen layout?

To present information clearly and simply so operators can quickly understand and control the system.

beginner

Why should important controls and indicators be placed prominently on an HMI screen?

Because placing key elements where they are easy to see helps operators react faster and reduces errors.

intermediate

What does consistency in HMI screen design mean?

Using similar colors, fonts, and layouts across screens so operators feel familiar and avoid confusion.

intermediate

How does grouping related information on an HMI screen help operators?

It makes it easier to find and understand related data quickly, like grouping all temperature controls together.

beginner

What role does color play in HMI screen layout?

Colors highlight status and alerts, guide attention, and improve readability when used thoughtfully and consistently.

What is the best place to put critical alarms on an HMI screen?

A Hidden in a menu to avoid distraction

B Mixed with unrelated information

C At the bottom corner of the screen

D In a prominent, easy-to-see area near the top or center

Critical alarms must be visible immediately to allow quick operator response.

Which principle helps operators quickly find related controls on an HMI screen?

A Random placement of controls

B Using many different fonts

C Grouping related information

D Using only black and white colors

Grouping related items together improves clarity and speed of use.

Why is consistency important in HMI screen design?

A It makes the system look more colorful

B It helps operators learn and use the system faster

C It allows mixing different styles freely

D It reduces the number of screens

Consistent design reduces confusion and speeds operator understanding.

What is a good use of color on an HMI screen?

A To highlight alarms and status changes

B To decorate the screen with random colors

C To make all text red

D To hide important information

Color should guide attention and indicate status clearly.

Which layout principle helps reduce operator errors?

A Clear and simple presentation of information

B Using as many controls as possible on one screen

C Hiding important controls in submenus

D Using flashing colors everywhere

Simple layouts help operators focus and avoid mistakes.

Explain the key principles to follow when designing an HMI screen layout.

Think about how to make the screen easy and quick to understand for operators.

Describe how color and grouping improve operator interaction with an HMI screen.

Consider how visual cues help in real-life situations.
