Best hmi panel manufacturer: The human factors to be considered in the analysis and design of human-machine interface mainly include the following: Human-computer matching: the user is a human being, the computer system as a human tool to complete the task, should make the computer and the human-computer system composed of a good match work; if there is a conflict, should let the computer to adapt to people, rather than people to adapt to the computer; Inherent human skills: As a computer user, people have many inherent skills. The analysis and synthesis of these abilities can help to estimate or judge the user’s ability to handle the complexity of the human-computer interface, and how much knowledge and help the user can get from the interface, as well as the time spent; Given this demand, future changes in the HMI will be in shape, in concept, and in application, thus bringing about a change in the core technology of industrial control machines. In general, the future development trend of HMI is six modernization: platform embedding, brand nationalization, equipment intelligence, interface fashion, communication network and energy saving and environmental protection.

The selection of PLC should be mainly considered from the PLC model, capacity, I/O module, power module, special function module, communication networking ability and other aspects. The basic principle of PLC model selection is to meet the functional requirements and ensure reliability and convenient maintenance, and strive for the best performance-price ratio. The selection should mainly consider reasonable structural type, installation method selection, corresponding functional requirements, response speed requirements, system reliability requirements, model as much as possible unified and other factors.
Interaction design is subordinate to the product system and is a strong support and refinement to successful product design. If we use the system theory point of view, interaction design is a subsystem of the product design system. Design Principles: The following principles should be considered for the design of human machine interface. The basic user-centered design principle: In the design process of the system, designers should grasp the characteristics of users and discover the needs of users. Users’ opinions should be constantly sought and consulted throughout the development process of the system. The design decisions of the system should be integrated with the users’ work and application environment, and the users’ requirements for the system must be understood. The best way is to involve real users in the development, so that developers can properly understand the needs and goals of users, and the system will be more successful.
It is good to choose a brand according to the needing of the customers or the market. But it is not for selecting a brand to decide, or more about to focus on its performance parameters, and to be used the functions achieved. Actually there is an attractive story behind the famous brand. So to choose a brand, try to achieve high practicality, to avoide waste one’s talent on a petty job. For example, Siemens, Mitsubishi, Proface, Panasonic brand…etc with a good performance, but before decision to select them, should consider, how many performance of HMI panel will be used for the project? Whether the cost paid matches the performance used on the project? See even more information at https://www.mochuan-drives.com/.
Specific methods : First, the parameters of the touch screen. Check the parameter settings of the touch screen. Connect the PLC programming software to the PLC test to see what the PLC parameters are and whether the parameters set in the project are the same as those tested. There are several parameters that require special attention: 1. Communication port settings – be sure to confirm that the COM1 port or COM2 port of the PLC connected to the touch screen is clear;2. Device type – this is the most important. If the protocol is not selected correctly, nothing else needs to be said. 3. connection method – the connection between the PLC and the HMI operator interface, confirming whether it is RS485 or RS232C. 4. The touch panel interface parameter is the same as the PLC station number – it must be the same as the setting in the PLC. Next, if the parameters are set to confirm, troubleshoot the wiring.
This type touchscreen panel support 7inch, 9.7inch, 17inch, 22inch and 32inch, is enough to select suitable model for the project from application and cost. There are two operating temperature -10°C to 60°C and -20°C to 70°C. And all the size and model is to support ethernet, 2pcs rs485 or 2pcs rs232 is in optional. Adpoting industrial grade high quality components, high protection level design, comprehensive three-proof coating, no matter the wet underground mine, high temperature gobi or corrosive gas, oil mist or dust factory environment, can easily cope with, easy to handle.
The regular China lcd human machine interface HMI touch screen is only to support 0°C to 50°C working envornment. HMI panel can not meet the application, the environment require the high or low temperature. It have to find the solution, such as to add one resistance or move the equipment in door or outdoor to make the temperature is suitabe its work needing. But face one question, it is not stable and very inconvenience. To solve this problem, to develop and design new type HMI touch panel, it is metal shell wide-temperature resistive HMI, supporting -20°C to 70°C. This type wide-temperature screen is very popular in Canada, Russia, United States…etc.
The Fourth Step: Communication Mode Preference is given to the HMI Panel itself with lower computer drive touch screen. Firstly, this is will be more convenient and simple in the definition of the subsequent project address and conversion, becuase if you choose Modbus compatible devices, it is necessary to convert the HMI touch screen monitoring address according to the rules of the definition of different lower computer(PLC) manufacturer, which not only greatly increase the workload of engineers and also easy to covert the wrong. Secondly, needing to draw up in advance, a communication program for the entire project. Do it need the ethernet to communicate with the upper computer, or need two rs485 to be maste or slave station communication, or through one rs485 and one rs232 communication to achieve.
At the same time, because the electrical room has the characteristics of complex data processing, many inverters, strong voltage interference, and closed space, the requirements for the configuration, stability, and anti-interference of the body are high. The industrial-grade control equipment can be well integrated into the electrical cabinet control equipment, and can effectively control all electrical equipment, in the current era of big data and the Internet of Things, and even directly through remote control equipment, the electrical cabinet equipment monitoring.
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.
