Human machine interface supplier in China: Inherent human weaknesses: people have inherent weaknesses such as forgetfulness, error-prone, inattentiveness and emotional instability. A well-designed human-machine interface should minimize the amount of user memory when operating and using, and should strive to avoid possible errors; The user’s knowledge and education: the user’s education level determines his knowledge and experience of the computer system. China is the world’s largest market in terms of HMI demand, but it is not the world’s highest market in terms of HMI product sales, which means that low-end HMI users occupy a large share in China. The rapid development of national brands in recent years, taking low prices and other strategies, is attacking the low-end market in a big way, and has occupied a dominant position in the low-end market in China, winning the recognition of the majority of users. International brands are also gradually developing their economic products to capture the share of the low-end market. As a result, the overall performance of domestic HMI manufacturers has shown rapid growth due to their steady presence in the low-end market. Find even more information at hmi touch screen panel.
Selecting the installation method: The installation mode of plc system is divided into centralized, remote i/o and distributed with multiple plc networking. Centralized hardware does not need to be set to drive remote i/o hardware, the system response is fast and cost is low; Remote I/O type is suitable for large systems, the system device distruibution range is very wide, remote i/o can be scattered installed near the field device, the connection is short, but need to add drivers and remote i/o power supply; The distrbuted network of multiple plc is suitable for the occasions where multiple devices are independently controlled and interconnected, and small plc can be selected, but communication module must be attaced.
Object-oriented principle: That is, according to the identity characteristics and work nature of the operator, design a human-machine interface that is compatible and friendly. According to their work needs, it is appropriate to display prompts, guidance and help information in pop-up windows, so as to improve the level of user interaction and efficiency. HMI, whether for the field controller or for the upper monitoring and management, the two are closely interconnected, they monitor and manage the field equipment objects are the same, so many field equipment parameters are shared between them and passed to each other. The standardized design of the human-machine interface should be the future development direction, because it really reflects the easy-to-configure, simple, and practical principles of the base, fully expressing the human-centered design concept. A variety of industrial control configuration software and programming tools provide powerful support for the production of a beautiful human-machine interface, and the larger and more complex the system, the more it can reflect its superiority.
MochuanDrives supports industrial hmi touch panel from 4.3inch to 32inch, and supports multiple serial ports with different communication parameters to meet the needs of different projects. Provide free software and online technical one-on-one worry-free after-sales technical support. Through the setting of early warning programming, can monitor in advance whether there is a failure of the equipment in the electrical room, can effectively prevent the loss of sudden damage to equipment.

The human-machine interface is the central link in the human-machine system, mainly by the safety engineering sub-discipline safety ergonomics to study and propose solutions based on the safety engineering equipment engineering, safety management engineering and safety systems engineering to study specific solutions and measures safety ergonomics. It realizes the conversion between the internal form of information and the acceptable form for human beings.
Less performance used to match a very high cost, so will it worth? And where is your market point? Maybe more consider another China brand with a very perfect performance too, such as Mochuan brand. Welcome contact us to discuss more. The Second Step: Selecting The HMI Screen Size There are two means of size here. One is screen display screen size, the other is CPU size. Integrating the scale of the entire project, to determine the size of the HMI panel needs, through the project as a whole to present the effect. Do not select the size is too small or too large, becuase too small is look very compact and not enough to operate in well, too large will look the overall proportion of the untuned and waste. It requires engineers to design a good enginnering diagram in advance to allocate the size of each accessory part of the proportion. Wanna win every high value market, it needs to pre-design and seriously selected, but not take for granted.
Use a multimeter to determine the test wiring according to the pins in the wiring diagram. Verify that the RS485 and RS232C wiring is correct, touch screens differ from various PLC wiring. This can be viewed by referring to Maintenance Control (help documentation for PLC and touch screen communication line connections), which is the basic method for normal troubleshooting of communication problems. Next I show you how to bypass the touch screen problem – online simulation. When communication fails, some customers will guess that there may be a problem with the touch panel interface or a problem with the interface. Online simulation means bypassing the touch screen and using the PLC to connect directly to the computer. Using our configuration software, the communication cable from the PLC itself is connected to the computer and an online simulation is carried out to see if the project can communicate. This can be done with a numerical input element or switch to see if the operation before and after closing the simulator and opening the online simulation is still present and if it prompts a direct NC (NC and previous operations not written down are not connected).
Multiple color of shell and panel cutout for selecting, it is more flexible to match different project to improve the overall aesthetics and practical. Suggestions and recommendations to our customers through over a decade field experience industry and industry solution through software and hardware, if you work with us. If require the special technology, special function, special size, special parameter, special color, shape or special performance of ihm, welcome contact us for ODM. Mochuan hmi panel manufacturers will be very seriously and give timely feedback.
There are lots of temperature control in industry automation. It can select temperature module match the main module plc temperature controller, it also use independent temperature controller to control, both of them are to achieve temperature control. If wanna more flexibility in temperature control, maybe indenpendent temperature module is the first choice. Becuase it can operate without main module plc controller. Mochuan independent plc temperature module integrates an excellent self-tuning algorithm, and user can auto-tune with one button according to needs to accurately obtain PID parameters. Through rs485 communication port, communicate with upper computers of various brands, types of plc, touch screen hmi, configuration software and other upper computers to complete morecomplex logic temperature control.
The reason is rs232 is suitable for communication between local devices, and its transmission distance is generally not more than 15m, and rs232 only allows one-ton-one communication. But rs485 transmission distance is from tens of meters up to 2Km, and rs485 interface allows up to 255 slave station to be connected. These are required to be designed by our engineers, with whom to communicate, how many devices to communicate, how to achieve the final function, whether to take into consider the interference problems of the field environment etc. All of the above are considered.
