Human machine interface provider today: Human-machine interfaces exist in all areas where human-machine information exchange is involved. A large number of industrial and commercial use, a simple distinction between “input” (Input) and “output” (Output) two, input refers to the operation of machinery or equipment by people, such as handles, switches, doors, instructions (orders) issued or maintenance, and output refers to the machinery or equipment issued by the notice, such as failure, warning, operating instructions tips, etc., a good human-machine interface will Help users more simple, more correct, more rapid operation of machinery, but also to maximize the performance of machinery and extend the service life, and the market refers to the human-machine interface is more narrowly defined in the software user-friendly operating interface.

Reasonable Structural Type: There are two structural types: main module and extended module. The average price of each I/O point of the integral PLC is cheaper than that of the module type, and the volume is relatively small, which is generally used in the small control system with a fixed system process; The function expansion of module plc is flexible and convenient, and there is a large choice in the number of I/O points, the ratio of input points to output points, the type of I/O modules…etc, and the maintenance is convenient, generally in more complex control systems.
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.
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.
There is no a good way that a conventional resistive screen can be implemented, becuase its only support the operation temperature from 0°C to 50°C, it is far enough to meet. But Mochuan have another series type HMI panel, wide-temperature metal shell resistive hmi panel, supporting the operation temperature from -20°C to +70°C, it is very helpful to require higher or lower operation temperature working environment, such as Canada, Russia and America …etc, when winter is coming the temperature is very low. So this type metal shell hmi panel is the best choice. So it requires a good positioning, what type of HMI screen to select. For example, used in the renovation of equipment, used in the new development of equipment, the target market is high-end or low-end, whether the customer has special requirements, or to achieve a certain expected results, these factors should be taken into account, and then to make a correct choice is very necessary.
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 additional information at https://www.mochuan-drives.com/.
Typically, a heartbeat detection is used to define the BOOL, the HMI sets this point at a fixed frequency and the PLC resets when it receives a signal that the point is on. If no signal is received for that point to turn on for a period of time, e.g. 5s, the communication is considered broken. The PLC’s memory clock byte is passed to the touch panel interface, which uses a script to assign the value of this byte to an address in another PLC, which then determines whether the two scan cycles of the returned byte are the same. If so, the communication is interrupted.
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.
Industrial grade fully enclosed embedded industrial hmi touch panel can perfectly cope with all kinds of harsh environment, but also can bring more convenient management services: Installation of embedded industrial hmi touch screen panel in the electrical room cabinet is more conducive to intelligent monitoring and management of the equipment in the electrical room. Through the touch screen monitoring display, you can monitor and detect the running temperature, power output, output power and other conditions of the electrical chassis cabinet in real time to ensure the stable and efficient operation of the electrical room.
