Introduction
The 4.3 Inch Serial Port HMI has a powerful database with a real-time database to store various data, such as analog, discrete, character type, etc., to realize data exchange with external devices. Secondly, we have a programmable command language. There is a programmable command language so that users can program according to their needs and rub a strong graphical interface. Finally, our products have the feature of ruggedness and durability.
Our company combines international advanced technology, constantly exploring in practice, and has always been in a leading position in the 4.3 Inch Serial Port HMI industry. Enterprise culture is the concentrated embodiment of enterprise spirit, excellent quality, value pursuit, civilized behavior, and credibility image. Our factory has strong funds, introduced advanced technology, and has achieved good business performance in the market, providing long-term services and products for famous domestic and foreign brands.
Feature
The 4.3 Inch Serial Port HMI has careful system safety precautions, giving different operating rights to different operators to ensure the safe and reliable operation of the entire system. Secondly, we support offline and online simulation, quickly verify your design effect, facilitate design and debugging, greatly reduce the burden of software developers in human-machine interface development and improve development efficiency, focus on the development of professional products, and avoid repetitive labor. The product development cycle is greatly shortened for you. Finally, our displays are touch-enabled for intuitive operator control.
