Hmi touch screen panel manufacturer by mochuan-drives.com: HMI is no longer a simple display and control: In the domestic automation industry, some industries that originally did not use HMI have started to use it, which shows that HMI has become an indispensable part of the customer experience. The user interface of HMI can better reflect the status of equipment and processes, and bring customers a more intuitive feeling through visual and touch effects. Future development trend of human-machine interface: Some mechanical industries, such as machine tools, textile machinery, electronic equipment and other industries, have been developed in China for decades and are relatively mature industries, and in the long run, there is still a demand for upgrading equipment in these industries. In this upgrading process, there will indeed be some small, has been using relatively low-end products manufacturers are eliminated, but there are also many enterprises in the process of equipment renewal, will demand repositioning, to find those who can meet their development plans, to help them improve their own productivity equipment suppliers.

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.

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. Find even more information at https://www.mochuan-drives.com/.

Typically, a heartbeat detection is used to define the BOOL, the HMI sets this point at a fixed frequency and the PLC resets when it receives a signal that the point is on. If no signal is received for that point to turn on for a period of time, e.g. 5s, the communication is considered broken. The PLC’s memory clock byte is passed to the touch panel interface, which uses a script to assign the value of this byte to an address in another PLC, which then determines whether the two scan cycles of the returned byte are the same. If so, the communication is interrupted.

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.

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.

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.

Choosing the right industrial hmi touch screen panel and plc can not only adapt to the electrical room’s multi-interference operation environment, but also enable each cabinet to achieve intelligent operation management, intelligent maintenance safety, intelligent new energy generation, etc., in order to achieve the goal of enhancing the electrical room’s core competitive advantage and promoting the sustainable development of electricity.

The human-machine interface is the central link in the human-machine system, mainly by the safety engineering sub-discipline safety ergonomics to study and propose solutions based on the safety engineering equipment engineering, safety management engineering and safety systems engineering to study specific solutions and measures safety ergonomics. It realizes the conversion between the internal form of information and the acceptable form for human beings.
