2020年8月7日 · Going Gray: A New HMI Standard Some standards for HMIs recommend monochromatic schemes for clarity. How can you help operators cope with a new HMI standard after many years of operating without one?

2016年11月18日 · Aiming for clarity in HMI, automation vendors like ABB are recommending cool, gray graphics to depict processes running normally. By reserving color for abnormal conditions, developing problems are more likely to stand out and draw an …

Everything is grayscale if it's running normally, but since I often worked with water systems, a grayish blue was good for animating tank levels and other water-based animations. I also used it for text that could change, such as a motor speed. This helped it stand out a little from grayscale labels without being distracting.

2000年9月3日 · Other conditions like "power available" can be shown as white, and "no power available" as gray. Interlock and permissive tree graphics work well on pumps, heaters and other devices with multiple conditions required to operate. Unless experienced with HMI systems, most customers don't know what they want.

2024年12月23日 · High Performance HMI is just a bunch of boring, grayscale, feature less screens, and it can’t make me a better Operator. Truth: The High Performance HMI standard covers a wide range of topics that simplify the interface, speed operator response time, improve problem and alarm resolution, while reducing errors and mistakes.

Even if there isn’t a written standard on what colors you should choose, there are some “best ways” to design graphic page and make HMIs as helpful as possible. This is the standard that i use as much as i can: Led : green for active, gray for inactive, red for alarm. Reserve leds: gray for inactive, red for alarm/reserve.

2024年5月23日 · A common high performance HMI practice is to use a dark gray to signify a "scheduled" state for equipment. This color should never compete with more alerting colors that "pop" from the HMI resulting in the viewer's eye's being drawn to the portion of the HMI where the problem may be occurring.

Upgrading to the latest High-Performance HMI standards empowers plant floor operators to perform their best work. We've found that HP HMI lowers the learning curve for new employees and encourages experienced operators and managers to find solutions to persistent problems.

2003年9月25日 · I recently saw a HMI for a gas plant that used all dark grey on light grey... unless something was abnormal. Then it would be outlined in a colour representing the abnormal state. So using a convention of red=stopped, green=running: A pump that was supposed to be running would be grey if running and red if stopped.
