Plc controller wholesale provider with mochuan-drives.com: 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.
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.
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? Read additional information on https://www.mochuan-drives.com/.
Why touch panel interface always fail to communicate with PLC? Common reasons why touchscreens do not communicate with PLCs 1. whether the correct communication protocol is selected (Modbus, Profibus, CANopen, etherCAT) 2. Is the communication line normal (RS232 rxd TXD GND RS485 a+B-CANopen CAN_L CAN_H CAN_GND ether cat network cable) 3. Whether the communication parameters are correct (station number, baud rate, parity bits) 4. Whether there is interference The program determines that the communication between HMI operator interface and plc has fialed
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 you have the requirement of HMI, it is good to description of your application and what function wanna realize, then the correct and the most suitable model will be recommended to you. Mochuan Drives offers three series of plc programmable logic controller, there are switch control and motion control with very strong power for choosing. Offering free software, demo, 36months warranty, mature solution. And one-to-one technical supporting online to fast solve the customer technical question. Supporting to take the video to solve the technical question, that is service do you need?
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.
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: According to the big data collected by the embedded industrial touch screen plus simple plc, the efficiency of each equipment in the electrical room can be monitored, so that the operation level of the electrical room can be improved and improved based on the evidence.
Human-Computer Interaction (HCI): The science of designing, evaluating, and implementing interactive computing systems for use by people and the study of these phenomena. HCI and human-computer interface are two concepts that are closely related but not identical. The RelationShip Between Human Computer Interaction and HMI: Human-computer interaction is the interaction between a human and a machine, which is essentially the interaction between a human and a computer. Or from a broader perspective: HCI refers to the interaction between a human and a machine containing a computer.
