Hmi touch screen wholesale manufacturer in China: Determine the task that should be performed by human and computer respectively to complete the system function: There are two ways of task analysis. One is to start from the actual, through the analysis of the original application system in a manual or semi-manual state, it will be mapped to a set of similar tasks performed on the human-computer interface; the other is to study the system requirements specifications to derive a set of user tasks coordinated with the user model and system assumptions. Techniques such as stepwise refinement and object-oriented analysis are also applicable to task analysis. Stepwise refinement techniques can continuously divide the task into subtasks until the requirements for each task are clear; and object-oriented analysis techniques can be used to identify all the objective objects associated with the application and the actions associated with the objects.

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.
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.

Human-machine interfaces exist in all areas where human-machine information exchange is involved. A large number of industrial and commercial use, a simple distinction between “input” (Input) and “output” (Output) two, input refers to the operation of machinery or equipment by people, such as handles, switches, doors, instructions (orders) issued or maintenance, and output refers to the machinery or equipment issued by the notice, such as failure, warning, operating instructions tips, etc., a good human-machine interface will Help users more simple, more correct, more rapid operation of machinery, but also to maximize the performance of machinery and extend the service life, and the market refers to the human-machine interface is more narrowly defined in the software user-friendly operating interface.
Wuxi Mochuan Drives Technology Co.,Ltd is one manufacturer and system solution company. To quickly match the high advantage competitive model through industry experience and solution to bring a high value market and a new growth point for our customers. We mainly provide Hmi Panel, Hmi Touch Screen , Plc Controller and permanent magnet motor.

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 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?
The reason is rs232 is suitable for communication between local devices, and its transmission distance is generally not more than 15m, and rs232 only allows one-ton-one communication. But rs485 transmission distance is from tens of meters up to 2Km, and rs485 interface allows up to 255 slave station to be connected. These are required to be designed by our engineers, with whom to communicate, how many devices to communicate, how to achieve the final function, whether to take into consider the interference problems of the field environment etc. All of the above are considered.
