- 🎥 An HMI or Human Machine Interface is simply a control unit that facilitates the integration of operators into complicated industrial processes by delivering a user-friendly dashboard.
By watching this video, you’ll get the answer to these questions:
- What is HMI?
- Why is HMI used?
- Where is HMI used?
- What is HMI design?
- How does HMI work?
- What is HMI software?
- What is HMI Hardware?
- What is the HMI function?
- What does HMI stand for?
- What are the types of HMI?
- What is HMI programming?
- What is the purpose of HMI?
- What are the advantages of HMI?
- How does HMI communicate with a PLC?

💬 Video Summary:
HMI Explained
- Because PLC is just hardware, it cannot display signal values instantly to operators unless technical staff with a personal computer and necessary software establish a connection to the PLC and check the program status online to keep an eye on signal values.
- It is not a practical method for operations employees to regularly check what the PLC is doing, and that’s where a human-machine interface, or HMI for short, comes into play.
HMI Types
- A variety of HMIs is available in an industrial setting, such as touchscreen, screen with buttons, built-in screen, handheld screen, computer screen, and mobile screen
HMI Hardware
- The hardware layouts of most actual HMIs are similar, which include the following: screen for monitoring, control panel, and communication port
HMI Software
- The software configurations of most genuine HMIs are alike, which applies in two steps.
- First, development. A personal computer is used to program the HMI through special software. And the Second step that applies in the HMI software configuration is runtime.
HMI Design
- If you are interested in HMI programming, you should consider some essential design tips, such as user awareness, visibility, simplicity, and consistency
HMI to PLC communication
- For the HMI to provide an interface for a manufacturing line, the HMI usually needs to be connected to a programmable logic controller or PLC.
- Compatibility between the HMI and PLC is required, meaning they must be able to communicate with one another.
HMI Operation:
- The PLC will receive information from sensors and will start processing the collected data into logical combinations.
- As soon as the PLC provides real-time data directly to the HMI, the HMI is used to convert complicated process variables into information in the form of a graphical way.
- At this point, the operator can send commands through the HMI screen, and the HMI will transfer user inputs to the PLC to be processed into the logical format.
- Then the PLC sends translated data to the actuators to be executed over a given industrial process system.
HMI Function
- Most HMIs have the same basic and extensively utilized functionality, such as monitoring, controlling, alarms management, data logging, and troubleshooting
HMI Advantages:
- And finally, let us talk about the benefits of implementing HMIs, including increased visibility, enhanced efficiency, decreased downtime, ensure safety, ease-of-use, and cost reduction.

I’m trying to land this robo tech support job at BMW, any tips? Or videos I should focus on?
Thanks 👍🏼
Allen Bradley in the middle of his Programmed OBSOLESENCE program already looks like APPLE, buy me every year. and they have their famous MOTTO: "why make it EASY if it can be made DIFFICULT" I am impressed by all the work that has to be done at the configuration and parameterization level with this type of BRANDS (siemens and allen bradley) and with other brands ALSO WITHOUT GIVING so many TURNS it comes to the same thing, I say it with absolute certainty of having worked with many brands for more than twenty years of Automation including those two (that is why they are asking for competitiveness in many areas) August 2023
Thank you for sharing your thoughts and insights! It's interesting to hear your perspective on Allen Bradley and their approach to programmed obsolescence. Automation brands like Siemens and Allen Bradley do have their unique characteristics and challenges in configuration and parameterization. However, we believe that each brand has its own strengths and considerations based on specific requirements.
In the end, the goal is to achieve the desired outcome efficiently. As an automation professional with over twenty years of experience, your insights carry weight. We appreciate your input and the competitiveness that exists in the industry.
