Best HMI manufacturer: Consider the typical problems in interface design: To design any interface, we must generally consider four aspects: system response time, user help mechanism, error message handling and command mode. System response time is too long is the most complained about in the interactive system, in addition to the absolute length of the response time, the user is concerned about the difference in response time of different commands, if too much disparity in the user will be difficult to accept; user help mechanism should be integrated, to avoid the superimposed system leads to the user to help a guide and have to browse a lot of irrelevant information; error and warning information must be selected user understandable The error and warning messages must be user-friendly, accurate terminology, and should also provide some suggestions for error recovery as much as possible. In addition, the display of error information, if supplemented by auditory (ringing), visual (special color) stimulation, it is more effective; command mode is best to menu and keyboard commands coexist for the user to choose.

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.
Frequency principle: That is, according to the frequency of dialogue interaction of the management object design the human-machine interface hierarchical order and dialogue window display position of the list, etc., to improve the frequency of monitoring and access to dialogue. Importance principle: That is, in accordance with the importance of management objects in the control system and the global level, the design of the human-machine interface of the main and secondary menus and the location and prominence of the dialogue window, which helps managers to grasp the importance of the control system, the implementation of good control of the sequence of decisions to achieve optimal scheduling and management.

Touch panel interface and PLC communication fail communication, needing check four factors: 1. Are the PLC parameters consistent with those in the project? 2. Are the communication lines connected according to the pins in the wiring diagram. 3. Is the COM port set in the project correct when connecting on the screen. 4. If it is confirmed that the parameters and wiring are OK, see whether it is the PLC program or the PLC address.
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.
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.
Human-machine interface refers to the field of human and machine in information exchange and functional contact or mutual influence or interface said human-machine bonding surface, information exchange, functional contact or mutual influence, refers to the hard contact and soft touch of human and machine, this bonding surface includes not only the direct contact of the point line surface, but also the role of space for information transfer and control at a distance.
