HMI Human Machine Interface factory in China: 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.

There are lots of temperature control in industry automation. It can select temperature module match the main module plc temperature controller, it also use independent temperature controller to control, both of them are to achieve temperature control. If wanna more flexibility in temperature control, maybe indenpendent temperature module is the first choice. Becuase it can operate without main module plc controller. Mochuan independent plc temperature module integrates an excellent self-tuning algorithm, and user can auto-tune with one button according to needs to accurately obtain PID parameters. Through rs485 communication port, communicate with upper computers of various brands, types of plc, touch screen hmi, configuration software and other upper computers to complete morecomplex logic temperature control.
The Third Step: Selecting Type of HMI Panel With the project and market demand and technology innovation, general resistive screen has no meet the new needs of the market and the high requirement of customers, thus deriving a new series of touch screen products, that is multi touch capacitive hmi, its high definition, highest bright, no drift, anti-scratech, supporting multi-touch to achieve special page effect. It is similar to our Apple iPhone, which is very popular in the market. If you are interested, you can have a try Mochuan Drives capacitive hmi panel type. Or to require the special operation temperature for the working environment.
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 even more details at 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).
