Human machine interface wholesale provider 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.
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.
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? Discover extra details at 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.
Mochuan hmi suppliers offer free software, NO MOQ, fast shipment, to deal with us your payment and business are in safe. Offering one-to-one technical support online. The most important, our hmi wholesale is compatible with all brands of plc controllers, such as, Mitsubish FX2N, FX3U, FX3SA, FX5U…Siemens S7-200, S7-300, S7-400,…etc, ABB, Acrel, Allen-Bradley(AB), Delta, Fatek, Fuji, LS, Omron, Panasonic etc. To learn, please have a look our software, there is one list to show it.
There are lots of temperature control in industry automation. It can select temperature module match the main module plc temperature controller, it also use independent temperature controller to control, both of them are to achieve temperature control. If wanna more flexibility in temperature control, maybe indenpendent temperature module is the first choice. Becuase it can operate without main module plc controller. Mochuan independent plc temperature module integrates an excellent self-tuning algorithm, and user can auto-tune with one button according to needs to accurately obtain PID parameters. Through rs485 communication port, communicate with upper computers of various brands, types of plc, touch screen hmi, configuration software and other upper computers to complete morecomplex logic temperature control.
There is no a good way that a conventional resistive screen can be implemented, becuase its only support the operation temperature from 0°C to 50°C, it is far enough to meet. But Mochuan have another series type HMI panel, wide-temperature metal shell resistive hmi panel, supporting the operation temperature from -20°C to +70°C, it is very helpful to require higher or lower operation temperature working environment, such as Canada, Russia and America …etc, when winter is coming the temperature is very low. So this type metal shell hmi panel is the best choice. So it requires a good positioning, what type of HMI screen to select. For example, used in the renovation of equipment, used in the new development of equipment, the target market is high-end or low-end, whether the customer has special requirements, or to achieve a certain expected results, these factors should be taken into account, and then to make a correct choice is very necessary.
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.
