Hmi panel wholesale manufacturer right now: 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.

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.
Consistency principle: Including the consistency of color, operation area consistency, text consistency. That is, on the one hand, the interface color, shape and font are consistent with national, international or industry common standards. On the other hand, the interface color, shape and font are self-contained, and the color of different devices and their same design state should be consistent. Consistency in the aesthetic design of the interface details makes the operator feel comfortable when looking at the interface, so as not to distract his attention. Consistency also reduces errors for new operators, or for operators dealing with problems in emergency situations.
Create the external model of the system function design model is mainly to consider the data structure, overall structure and process description of the software, interface design is generally only as an accessory, only the user’s situation (including age, gender, psychological situation, literacy, personality, ethnic background, etc.) have an understanding of the user to design an effective user interface; according to the end user’s hypothesis of the future system (referred to as the system hypothesis) The user model is designed to match the system image (external characteristics of the system) obtained after the system is implemented, so that the user can be satisfied with the system and can use it effectively; the information given by the system hypothesis should be fully considered when building the user model, and the system image must accurately reflect the syntactic and semantic information of the system. In short, only by understanding the user and the task can a good human-machine interface be designed.
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.
Supporting customized special technical parameters, special application scenarios or special process, special function realization, special performance, special application including shape, color etc. With NO MOQ before mass production. And will not accept to quantity production before customer 100% confirmation its stable quality to run in the device or equipment. Becuase quality is the soul of an enterprise. MochuanDrives customized pmsm motor mainly focuses on high-tech , high-end development, design, production, sales. Read more info on https://www.mochuan-drives.com/.
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.
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 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.
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.
