Quality hmi panel factory: Create the external model of the system function design model is mainly to consider the data structure, overall structure and process description of the software, interface design is generally only as an accessory, only the user’s situation (including age, gender, psychological situation, literacy, personality, ethnic background, etc.) have an understanding of the user to design an effective user interface; according to the end user’s hypothesis of the future system (referred to as the system hypothesis) The user model is designed to match the system image (external characteristics of the system) obtained after the system is implemented, so that the user can be satisfied with the system and can use it effectively; the information given by the system hypothesis should be fully considered when building the user model, and the system image must accurately reflect the syntactic and semantic information of the system. In short, only by understanding the user and the task can a good human-machine interface be designed. Discover additional information at hmi display panel.
System Reliability Requirements: The reliability of the general system PLC can be met. For systems with high reliability requirements, consider whether to use redundant systems or hot standby systems. PLC should be unified possible. Mainly consider the following three aspects: The model is unified, and its modules can be used as backup for each other, which is convenient for the procurement and management of spare parts. The model is unified and its function and use method are similar, which is conducive to the training of technical forces and the improvement of technical level. The model is unified, its external equipment is universal, resources can be shared, easy to network communication, and it is easy to form a multi-level distributed control system after being equipped with a computer.
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.
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.

Specifically, the two-way communication between the HCI user and the machine containing the computer, in a certain symbol and actions to achieve, such as hitting keys, moving the mouse, displaying symbols/graphics on the screen, etc. This process includes several sub-processes: identifying the interactive object – understanding the interactive object – grasping the object situation – information adaptation and feedback, etc.; and the human-machine interface is the communication media or means between the user and the machine system containing the computer, which is the software and hardware supporting the two-way information interaction between human and machine. Here the interface is defined as the media or means of communication, and its physical embodiment is the relevant supporting software and hardware, such as a graphic display terminal with a mouse, etc.
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?
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.
The Fifth Step: Selecting A Supplier The correct undertanding of a supplier is to be able to provide very stable performance products and after sale and technical service, can do online one-to-one timely guidance and solution. In the face of unforeseen events have the feasibility and flexibility of the program to provide. After all, industrial HMI PLC is a technical product, needing for a manufacturer’s cooperation and support, to make customer worry-free. Maybe you can choose Mochuan Drives. A small try will bring a high value, so why not try?
