Human machine interface supplier right now: 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.

The selection of PLC should be mainly considered from the PLC model, capacity, I/O module, power module, special function module, communication networking ability and other aspects. The basic principle of PLC model selection is to meet the functional requirements and ensure reliability and convenient maintenance, and strive for the best performance-price ratio. The selection should mainly consider reasonable structural type, installation method selection, corresponding functional requirements, response speed requirements, system reliability requirements, model as much as possible unified and other factors.
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.
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. Discover even more information at 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
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.
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.
In the wisdom of industry, electrical cabinet control equipment is suitable for electric facilities, chemical plants, mechanical plants, plant electrical control, network companies electrical control, site large electrical equipment control, etc., to provide convenient electrical management services for the majority of enterprises. Whether it is a small or large electrical cabinet control equipment, it can easily manage the whole company, the whole enterprise, the whole factory electrical equipment.
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.
