Hmi touch screen panel wholesale manufacturer in China: 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.

Corresponding Functional Requirements: Gemerally, small plc have functions such as logic operation, timing and counting, which can be met for equipment that only needs to be controlled by switching quantity. For systems with switching control as the main and a small number of analog control, an enhanced plc with A/D and D/A conversion units and functions of addition and subtraction arithmetic operations and data transmission can be selected. For complex control, it is required to realized PID calculation, closed-loop control, communication networking and other functions, visual control scale and complexity, and choose mid-range or high-grade plc. However, medium and large PLC are more expensive and are generally used in large-scale process control and distributed control system.
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.
Less performance used to match a very high cost, so will it worth? And where is your market point? Maybe more consider another China brand with a very perfect performance too, such as Mochuan brand. Welcome contact us to discuss more. The Second Step: Selecting The HMI Screen Size There are two means of size here. One is screen display screen size, the other is CPU size. Integrating the scale of the entire project, to determine the size of the HMI panel needs, through the project as a whole to present the effect. Do not select the size is too small or too large, becuase too small is look very compact and not enough to operate in well, too large will look the overall proportion of the untuned and waste. It requires engineers to design a good enginnering diagram in advance to allocate the size of each accessory part of the proportion. Wanna win every high value market, it needs to pre-design and seriously selected, but not take for granted. See additional info at mochuan-drives.com.
Use a multimeter to determine the test wiring according to the pins in the wiring diagram. Verify that the RS485 and RS232C wiring is correct, touch screens differ from various PLC wiring. This can be viewed by referring to Maintenance Control (help documentation for PLC and touch screen communication line connections), which is the basic method for normal troubleshooting of communication problems. Next I show you how to bypass the touch screen problem – online simulation. When communication fails, some customers will guess that there may be a problem with the touch panel interface or a problem with the interface. Online simulation means bypassing the touch screen and using the PLC to connect directly to the computer. Using our configuration software, the communication cable from the PLC itself is connected to the computer and an online simulation is carried out to see if the project can communicate. This can be done with a numerical input element or switch to see if the operation before and after closing the simulator and opening the online simulation is still present and if it prompts a direct NC (NC and previous operations not written down are not connected).
The Macro instructions of HMI Human Machine Interface are based on C language and the system is developed on Linux. There are multi-types of HMI panel, mainly three types, multi touch capacitive hmi panel, plastic shell enconomic resistive hmi touchscreen panel and metal shell wide-temperature resistive touch screen and small home screen to meet different requirement from application scenarios and market needing. There are rich serial port such as rs485, rs232, rs422, ethernet etc to meet the master and slave to use. Mochuan human machine interface manufacturer suppors the size from 4.3inch to 32inch.
The size range is 4.3inch, 7inch, 9.7inch, 10.1inch, 12inch and 15inch, with ethernet, RS485, RS232 and RS422 to meet different application using. 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.
Electrical cabinets are integrated cabinets used to accommodate electrical or various electrical equipment used as a carrier for electrical control equipment. It can provide strong protection against water, dust and electromagnetic interference to the stored objects. In the era of big data and the construction of intelligent industry, electrical cabinet control equipment is also playing a very important role. How can we better control the electrical equipment in the harsh environment of the electrical room? Here we recommend Mochuan drives industrial hmi touch panel for embedded installation.
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.
