. It signals that a situation is approaching a critical limit and requires monitoring. : Represents

High-priority or "Start" controls are typically placed at the top. "Stop" or lower-priority controls sit at the bottom.

: Used for intervention commands to suppress abnormal conditions (e.g., reset an alarm).

While many engineers chase the latest HMI software, they forget the basics of human psychology. IEC 60073 defines the for indicators and actuators. iec 60073 pdf

A: IEC 60073 is the international standard that defines basic and safety principles for human-machine interfaces by standardizing coding for indicators and actuators using visual, acoustic, and tactile signals.

IEC 60073, officially titled "Basic and safety principles for man-machine interface, marking and identification - Coding principles for indicators and actuators," is published by the International Electrotechnical Commission (IEC).

Buttons may feature raised ridges, rough surfaces, or distinct borders to differentiate a "start" function from a "stop" function without looking. Why Professionals Search for the "IEC 60073 PDF" "Stop" or lower-priority controls sit at the bottom

Indicates safe conditions, normal operation, or that a system is ready to start.

For environments where visibility is severely compromised, texturing the surface of the actuator provides an extra layer of clarity. Rough, smooth, raised, or recessed surfaces allow operators to verify the button's function blindly. 3. Acoustic (Sound) Coding

| Actuator Type | Mandatory or Prohibited Colors | | :--- | :--- | | | Must be identified by the color RED . | | STOP / OFF (normal operation) | Preferred : White, Grey, Black. Permitted : Red. Prohibited : Green. | | START / ON | Preferred : White, Grey, Black. Permitted : Green. Prohibited : Red. | | Inching / Jogging | Preferred : White, Grey, Black. Permitted : Green. Prohibited : Red. | | RESET | Preferred : Blue, White, Grey, Black. | IEC 60073 defines the for indicators and actuators

The standard assigns specific meanings to visual and physical attributes. The primary coding methods include colors, shapes, and acoustic signals, with color being the most widely recognized. 1. Color Coding for Indicators (Lights and Screens)

Guidelines on the frequency, pulse duration, and pitch of buzzers and sirens to match the visual urgency levels.
