Hmi touch screen supplier in China: 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. Read even more details at plc controller.

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.

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.

HMI is no longer a simple display and control: In the domestic automation industry, some industries that originally did not use HMI have started to use it, which shows that HMI has become an indispensable part of the customer experience. The user interface of HMI can better reflect the status of equipment and processes, and bring customers a more intuitive feeling through visual and touch effects. Future development trend of human-machine interface: Some mechanical industries, such as machine tools, textile machinery, electronic equipment and other industries, have been developed in China for decades and are relatively mature industries, and in the long run, there is still a demand for upgrading equipment in these industries. In this upgrading process, there will indeed be some small, has been using relatively low-end products manufacturers are eliminated, but there are also many enterprises in the process of equipment renewal, will demand repositioning, to find those who can meet their development plans, to help them improve their own productivity equipment suppliers.

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.

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. Find extra info 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).

Multi-touch capacitive hmi panel is new design and very popular with the market. Why? It is similar the Apple iPone in our life. Becuase its flexible multi touch, very high transmittance, Glass+Glass, anti-scratching, no drifting, IPS full view TFT lcd, high resolution, brightness, high speed and easy flow, supporting animation formats. The color of multitouch HMI is rich and the picture displayed is more delicate. Why many people follows iPhone, just becuase it can bring the users different and beyond imagination experience. Same reasons, why this type panel hmi is very popular in European and American market, just becuase it can bring the project, equipment different experience then to obtain more high value market and to be easily competitive the competitors. Maybe a little try, but to bring a large value, so why not try.

The plastic enconomic resistive HMI panel is very high advantage competitive series. There are multiple parameter, resolution, serial port to select for user to achieve real matching per project budget for one size. But it does not mean, this type HMI touch panel performance, resolution…etc is not in perfect but more flexible. For example, there are 800×480, 1024×600 resolution, ethernet, 2xRS485, 2xRS232, RS422 are in optional for 7inch touchscreen HMI.

Choosing the right industrial hmi touch screen panel and plc can not only adapt to the electrical room’s multi-interference operation environment, but also enable each cabinet to achieve intelligent operation management, intelligent maintenance safety, intelligent new energy generation, etc., in order to achieve the goal of enhancing the electrical room’s core competitive advantage and promoting the sustainable development of electricity.
