High quality hmi factory: 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.
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.
In 2022, in order to meet the new needs of customers and the market, our MochuanDrives merged with a professional manufacturer of highly customized servo motors, with more than 20 years of experience in research and development, manufacturing and service of servo motors and brushless motors, especially good at tailor-made high-end motors with special specifications from scratch, until the stable manufacturing of large quantities. With NO MOQ, before large quantities needing to get 100% stable quality confirmation from our customers. Read extra details on 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.
