HMI Defined

First consider the other components that are necessary to make a manufacturing control system operate. The production line consists of all the machinery that performs the work required in the production of the product.

The operating environment should always be considered when selecting an HMI. For example: If used in the food processing industry or somewhere that might need to be washed down, select a water-protected HMI.

One must also consider temperature as a factor in the selection process. If used in a steel plant, next to a furnace, one would want something that can withstand extreme temperatures. When considering which programming software to use, there are three main categories to choose from: Proprietary software is the software that the manufacturer provides, which is typically easy to use and allows for quick development.

The drawback is that proprietary software will only run on that specific hardware platform. Hardware-independent software is third party software developed to program on several different types of HMIs. This type of software gives the developer much more freedom for the HMI selection.

The downside to hardware independent software is that it is not as user-friendly as the proprietary. Open Software should only be selected by the advanced programmer.

It allows the developer to have complete openness in the design process. The HMI is used throughout various industries including manufacturing plants, vending machines, food and beverage, pharmaceuticals, and utilities, just to name a few. The integration of the HMI into manufacturing has vastly improved operations. The HMI allows for supervisory control and data acquisition in the entire system, so parameter changes are feasible as the operator's choosing.

For example, in metals manufacturing, an HMI might control how metal is cut and folded, and how fast to do so. An HMI offers improved stock control and replenishment, so the fewer journeys are required out to the vendors.

HMIs are used in bottling processes to control all aspects of the manufacturing line, such as speed, efficiency, error detection and error correction. Utility companies may use HMIs to monitor water distribution and waste water treatment. The greatest advantage of an HMI is the user-friendliness of the graphical interface.

The graphical interface contains color coding that allows for easy identification for example: Pictures and icons allow for fast recognition, easing the problems of illiteracy. HMI can reduce the cost of product manufacturing, and potentially increase profit margins and lower production costs. HMI devices are now extremely innovative and capable of higher capacity and more interactive, elaborate functions than ever before. Some technological advantages the HMI offers are: Using just a PLC will not provide any real-time feedback, cannot set off alarms nor modify the system without reprogramming the PLC.

The key advantage to an HMI is it functionality; an HMI can be used for simple tasks such as a coffee brewing controller, or a sophisticated control unit of a nuclear plant.

Advancement and Application of Unmanned Aerial System Human-Machine-Interface (HMI) Technology

With new HMI designs emerging every day, we are now seeing HMIs that offer remote access, allowing for access of the terminal while away. Another advantage of an HMI is that the user can personally design the user interface. The convenience that comes with an HMI is extremely valuable; the functionality achieved with digitizing a system with an HMI is unbeatable.

HMI combines all the control features that are typically found throughout the automation line and places them in one centralized location, eliminating the need to run to a red pushbutton that will stop your line in an emergency.

With remote access, the operator can have all the same features, on your centralized unit in a smaller compact form. Simplicity is also a big factor in the usability of an HMI. The screens and functions provide for easy training to supervise the automation line. One of the most convenient features of an HMI is the ability to personalize the interface.

An HMI can fully support the most complex applications, with multiple screens and several routines running. Every HMI comes with different features; some may play sound, play video, or even may have remote access control. The design of the actual interface should be optimized for specific applications, taking into consideration all the capabilities of the typical user, as well as the environmental aspects such as noise, lighting, dust, vision and technological curves.

How can a PLC be controlled without ladder logic? Ladder logic is simply conditional programming. For example, if input 1 is energized, then coil 1 will be powered. A statement has to be true for the output to be executed.

The same can be achieved with C programming. That knowledge will easily transfer over when the user is ready to connect the two units together.

In some instances, both units are equipped with wireless features, making the connection even easier. Depending on the size and complexity of the application, profibus extensions may be required for the PLC.

A wiring schematic from the production line to the PLC is highly recommended, so that programming the HMI is sped up drastically.

To troubleshoot the error, simply use a numeric display and set it to the PLC register the data is being written to. If this PLC register comes back with random register values, this indicates that the HMI did not deliver the information to that register.

If it was sent correctly, then the numeric displays should show the information that was sent. HMI products originated from the need to make machinery easier to operate, while producing optimal outputs.

The Batch Interface is a non-interactive user interface, where the user specifies the details to the batch process in advance, and receives the output when all the processing is done. This batch process does not allow for additional input once the process has begun, is problematic in modern manufacturing lines. The Command-Line Interface is a mechanism that interacts with a computer operating system or software by typing commands to perform specific tasks.

The concept of the Command-Line interface originated when teletypewriter machines were connected to computers in the s, and offered results on demand; a big downfall of Batch Interface because it could not deliver results on demand.

Over time, interfaces became highly complex and extremely easy to use. Graphical User Interface allows people to interact with programs in more ways than typing, such as computers, hand-held devices such as MP3 Players, Portable Media Players or Gaming devices, household appliances, and office equipment with images, rather than text commands.

Human Machine Interface stems directly from Graphical User Interface, and comes from the need to control and operate machinery much more effectively. Human Machine Interface formerly known as Man Machine Interface , is now leading the way in the control of manufacturing processes as an extremely user-friendly device. HMI Quiz.

What does HMI stand for? The MT is the complete package, although it has the same processing power as the MT PLCs tend to be complex, with many wires connected to them, making it difficult to find the correct input to manually toggle.

HMIs also provide a real time view of the system, so if recipe memory in the PLC was to max out, the user could easily wipe its contents without having to disconnect the PLC. What is a Baud Rate? Baud, synonymous to symbols per second, or pulses per second, is often times referred to as the unit of the symbol rate.

It is the number of distinct symbol changes made to the transmission medium per second in a digitally modulated signal or a line code. What communication protocols are applicable to our HMI line?The best interface is the invisible one, the Unfortunately, rules sometimes contradict and overlap each interface should "disappear" to allow the user to concentrate other, as they are every detailed and try to give indications attention only on the task.

To satisfy more demanding customers, system personalization also needs to be considered as well II. The same can be achieved with C programming. What communication protocols are applicable to our HMI line? It allows the developer to have complete openness in the design process. Other design elements, like color, size, and placement, are used with discretion to optimize the user experience.
