Excellent hmi touch screen panel manufacturer and supplier: Order principle: That is, in accordance with the order of processing events, access to view the order (such as from the whole to a single item, from large to small, from the top to the bottom, etc.) and control processes, such as the design of monitoring management and human-machine dialogue interface and its secondary interface. Functional principle: That is, according to the specific functional requirements of the object application environment and occasions, various subsystem control types, parallel processing requirements of the same interface of different management objects and simultaneous requirements of multiple dialogues, etc., the human-computer interaction interface is designed with multi-level menus, hierarchical prompt messages and multiple dialogues, so that users can easily distinguish and master the usage rules and characteristics of the interactive interface and improve its user friendliness and ease of operation.

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.
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.
Selecting HMI screen hardware parameters, mainly look at the CPU running speed and the capacity of the memory. According to the project involves the amount of data exchange animation, the size of the pictures to choose the CPU and memory. When processing more data and picture format is large, needing to choose a fast running speed, memory slightly large HMI. For example, Mochuan 15.6Inch MC-H156E, 7Inch MC-H070CWE, MC-H070CW with 1GHz CortexTM-A7 in CPU. And 10.1Inch MC-H100C, MC-H100CWE with 1GHz cortexTM-A7 and 4GB Flash memory. In addition, also needing to consider the functional requirements needed in the project, such as, how to achieve the multi-level tital pop-up, whether the screen display meets the customer’s need…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? Find additional details at https://www.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?
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.
