Hmi touch screen panel supplier right now: 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. Discover additional information at hmi touch screen.
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.
Interaction is a description of the relationship/status of human-machine-environment interaction. The interface is a concrete expression of the interaction between human and machine – environment. Interaction is the contextual portrayal to achieve information communication, and interface is the means to achieve interaction. In the interaction design subsystem, interaction is the content/soul, and interface is the form/body; however, in the larger product design system, both interaction and interface are only a means to solve the human-machine relationship, not the ultimate purpose, which is to solve and satisfy human needs.
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? Read additional info on https://www.mochuan-drives.com/.
Specific methods : First, the parameters of the touch screen. Check the parameter settings of the touch screen. Connect the PLC programming software to the PLC test to see what the PLC parameters are and whether the parameters set in the project are the same as those tested. There are several parameters that require special attention: 1. Communication port settings – be sure to confirm that the COM1 port or COM2 port of the PLC connected to the touch screen is clear;2. Device type – this is the most important. If the protocol is not selected correctly, nothing else needs to be said. 3. connection method – the connection between the PLC and the HMI operator interface, confirming whether it is RS485 or RS232C. 4. The touch panel interface parameter is the same as the PLC station number – it must be the same as the setting in the PLC. Next, if the parameters are set to confirm, troubleshoot the wiring.
This type touchscreen panel support 7inch, 9.7inch, 17inch, 22inch and 32inch, is enough to select suitable model for the project from application and cost. There are two operating temperature -10°C to 60°C and -20°C to 70°C. And all the size and model is to support ethernet, 2pcs rs485 or 2pcs rs232 is in optional. Adpoting industrial grade high quality components, high protection level design, comprehensive three-proof coating, no matter the wet underground mine, high temperature gobi or corrosive gas, oil mist or dust factory environment, can easily cope with, easy to handle.

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.
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.
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.
