Hmi panel factory by mochuan-drives.com: 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. Read additional details on https://www.mochuan-drives.com/.
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.
Frequency principle: That is, according to the frequency of dialogue interaction of the management object design the human-machine interface hierarchical order and dialogue window display position of the list, etc., to improve the frequency of monitoring and access to dialogue. Importance principle: That is, in accordance with the importance of management objects in the control system and the global level, the design of the human-machine interface of the main and secondary menus and the location and prominence of the dialogue window, which helps managers to grasp the importance of the control system, the implementation of good control of the sequence of decisions to achieve optimal scheduling and management.
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: Installation of embedded industrial hmi touch screen panel in the electrical room cabinet is more conducive to intelligent monitoring and management of the equipment in the electrical room. Through the touch screen monitoring display, you can monitor and detect the running temperature, power output, output power and other conditions of the electrical chassis cabinet in real time to ensure the stable and efficient operation of the electrical room.

Human-Computer Interaction (HCI): The science of designing, evaluating, and implementing interactive computing systems for use by people and the study of these phenomena. HCI and human-computer interface are two concepts that are closely related but not identical. The RelationShip Between Human Computer Interaction and HMI: Human-computer interaction is the interaction between a human and a machine, which is essentially the interaction between a human and a computer. Or from a broader perspective: HCI refers to the interaction between a human and a machine containing a computer.
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.
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.
The Macro instructions of HMI Human Machine Interface are based on C language and the system is developed on Linux. There are multi-types of HMI panel, mainly three types, multi touch capacitive hmi panel, plastic shell enconomic resistive hmi touchscreen panel and metal shell wide-temperature resistive touch screen and small home screen to meet different requirement from application scenarios and market needing. There are rich serial port such as rs485, rs232, rs422, ethernet etc to meet the master and slave to use. Mochuan human machine interface manufacturer suppors the size from 4.3inch to 32inch.
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.
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.
