Excellent hmi panel manufacturer and supplier
Quality human machine interface factory: 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. Read additional details on hmi panel.
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.
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.
Supporting customized special technical parameters, special application scenarios or special process, special function realization, special performance, special application including shape, color etc. With NO MOQ before mass production. And will not accept to quantity production before customer 100% confirmation its stable quality to run in the device or equipment. Becuase quality is the soul of an enterprise. MochuanDrives customized pmsm motor mainly focuses on high-tech , high-end development, design, production, sales. Find additional details on https://www.mochuan-drives.com/.
Use a multimeter to determine the test wiring according to the pins in the wiring diagram. Verify that the RS485 and RS232C wiring is correct, touch screens differ from various PLC wiring. This can be viewed by referring to Maintenance Control (help documentation for PLC and touch screen communication line connections), which is the basic method for normal troubleshooting of communication problems. Next I show you how to bypass the touch screen problem – online simulation. When communication fails, some customers will guess that there may be a problem with the touch panel interface or a problem with the interface. Online simulation means bypassing the touch screen and using the PLC to connect directly to the computer. Using our configuration software, the communication cable from the PLC itself is connected to the computer and an online simulation is carried out to see if the project can communicate. This can be done with a numerical input element or switch to see if the operation before and after closing the simulator and opening the online simulation is still present and if it prompts a direct NC (NC and previous operations not written down are not connected).
