Human-machine interface products consist of two parts: hardware and software. The hardware part includes processor, display unit, input unit, communication interface, data storage unit, etc. The performance of the processor determines the performance of the HMI product and is the core unit of the HMI. According to the different product levels of the HMI, the processor can be selected as 8-bit, 16-bit, or 32-bit processors. HMI software is generally divided into two parts, namely the system software running in the HMI hardware and the screen configuration software running under the Windows operating system of the PC (such as JB-HMI screen configuration software). Users must first use the HMI screen configuration software to create a "project file", and then download the compiled "project file" to the HMI processor through the serial communication port of the PC and the HMI product for operation.
