Most people think of a human-machine interface as a digital device that can be controlled with simple software applications. While this is true in many cases, it’s important to think of them from a different perspective. The important thing here is not the software but how your end users interact with the device to achieve their tasks. HMI stands for Human-Machine Interface, and it’s a means of linking the human operator (or user) to the machine they’re operating (or controlling). The typical examples of a HMI are the buttons, switches, dials, gauges, and displays on any piece of machinery. The software that controls these devices is referred to as the machine’s “tachogenerator.”
There are times when end users can control the machine without needing to know how to use the controls at all. These are referred to as “touchless” controls and are used for simple tasks like power on and off, or to tell the machine to go forward or make a U-turn. Other times, the user needs to know how to operate the controls and perform more complex tasks. These are called “touch-based” controls, and require the user to know how to operate the machine. A well-functioning HMI uses a combination of “touchless” and “touch-based” controls so that the end user only needs to
HMI repair is the process of restoring, testing, and repairing a variety of equipment that includes HMI devices, software, and embedded systems. It includes repairing damaged, non-functioning, or incorrect equipment, as well as ensuring that the equipment is properly installed, wired, powered, and configured to operate correctly. HMI repair is often overlooked as it is difficult to attract attention to a niche service. The need for HMI repair is enormous, but it is generally under-marketed, under-utilized, and under-billed, due to the lack of awareness of the need for these services.
Our experienced repair engineers have the expertise to repair all brands of Siemens HMI devices. We are a Siemens authorised repair centre and can repair all Siemens appliance brands both domestic and commercial. We have a track record of being able to repair most of our customers’ HMI issues; however, as with any repair, if we are unable to do so, we are happy to quote a repair fee.
Programmable Logic Controller (PLC) - A PLC is a computer programmable logic controller, often found in industrial and commercial buildings.
The PLC allows a set of logic rules that govern the operation of the equipment to be written inside the device. - A PLC is a computer programmable logic controller, often found in industrial and commercial buildings.

When you need to operate equipment such as lights or fans, you may not need to know the specific controls for them. Instead, a “touchless” control may let you tell the device to turn on or off, or change the brightness or set the timer. The control may also have a button that lets you see on the screen what the settings mean. This may be enough for basic tasks like changing the lights on a wall or a lamp. You may also be able to use voice commands to change the settings.
When you need to operate equipment such as pressure gauges, valves, compressors, or fans, you cannot tell them to turn on without knowing how to operate them. The controls may be “touch-based,” requiring you to know how to operate them using the traditional methods. There are certain advantages to using these controls, however. For example, you may be able to operate the equipment without having to look at them, or without wearing the right protective gear. You may also be able to operate multiple pieces of equipment with just one set of controls.
HMI repair can be a challenging job, as there are numerous factors to take into account. It’s important to know that repairing a faulty device is not easy. The device may have been damaged, and there may be a delay in being able to detect the damage. It’s important to have the right tools, know how to use them, and be able to discern the difference between a fault and normal operation of the equipment.
