HMI is the abbreviation of human machine interface, which is also known as user interface. It is the medium of interaction and information exchange between the system and users.
It can complete the work of information transformation between the internal form of machinery and the acceptable form of human beings.
Wherever there’s human-computer information exchange, there’s HMI.

Figure 2: 5.7 inches HITECH HMI PWS5610T-S
HITECH is a brand in Taiwan and is called Hetek in Chinese mainland. It is the brand of Taiwan HITECH Electronics Co., Ltd. founded in 1981, the company initially manufactured electronic watches for pens.
In order to transform HITECH into a technology-oriented company, the company began to develop and manufacture LCD modules in 1984.
At that time, HITECH was the first manufacturer in Taiwan to successfully develop LCD modules.
In 1990, HITECH set up a new Research & Development department to actively invest in the research and development of human machine interface (HMI) applied in the field of industrial automation.
HITECH is the first manufacturer in Taiwan to develop industrial HMI products by combining embedded system technology with LCD module.
After years of efforts, HITECH has established its own HMI brand - HITECH PWS series, with sale bases all over the world, including Asia, the United States and Europe. Now it has been acquired by Swedish BEIJER and has been put under BEIJER.
Beijer Electronics Group of Sweden is the first HMI brand in Europe, and it has won the best IF design award of global industrial design for three years continuously.
Beijer adopts aluminum magnesium alloy shell design, which is thin and has strong anti-interference ability. Its HMI screens are of 64ktft true color display with beautiful and clear picture, and the embedded WinCE operating system has powerful function and high reliability.
The protection grade of the front panel is IP66, and it has passed various certification of UL, DNV, and RoHS.

Beijer is a technology independent HMI developer. With its intuitive HMI and information software, users all over the world can easily communicate with the machines and processes they control.
HMI is the only business of Beijer. Since the 1980s, Beijer electronics has become a leading enterprise in the development of HMI.
Here are some of the major events in the history of Beijer.
* In 1981, Beijer Electronics was founded. It started as an automation system agent and then developed proprietary control products, which laid the foundation for the company's HMI business.
* In 1986, Beijer electronics released the first HMI MAC-G. This is a handheld HMI with a text display. Other models were introduced in subsequent years.

* In 1996, Beijer introduced color graphic display and touch screen.
* In 1997, Beijer introduced the Ethernet function based on TCP / IP.
* In 1998, Beijer electronics became the first enterprise to provide HMI with web function. In addition to handling e-mail, you can use the HMI as a web server. Moreover, you can also monitor and control it through intranet and Internet.
* In 2005, Beijer electronics successfully acquired HITECH Electronics Corp, a Taiwan company engaged in HMI development and sale.
* In 2007, Beijer electronics successfully acquired Lauer, a German HMI manufacturer with significant influence in Central Europe.
At present, Beijer sells HMIs in the Chinese market through Tianjin Luosheng, but with limited sales. The company now mainly develops the Chinese market through HITECH.

Figure 6: Mitsubishi HMI product with brief company description
Mitsubishi Electric Automation (China) Co., Ltd. is the sales and service organization of industrial automation products of Mitsubishi group in China. Its business scope covers industrial automation and mechatronics products, including PLC (programmable logic controller), HMI, VFD (variable frequency drive), AC servo system, numerical control system, etc.
At present, Mitsubishi has 3 series of PLCs: the Q series (medium sized), FX series (small sized), L series (medium and large sized). Among these series, Mitsubishi small PLC of FX series entered the domestic market early, and now it has a very high share in the global market.
Mitsubishi HMI include GT10 series, GT15 series, GT11 series, GOT-F900 and GOT1000.
For now, Mitsubishi's HMI is basically matched with Mitsubishi's PLC, so its PLC market share determines that its HMI market share is accordingly large.
But in recent years, many other HMI brands have occupied the market share of Mitsubishi's HMI, making its HMI sale seriously decreased.
