Composition and working principle of Human-Machine Interface (HMI) products
Human-Machine Interface ( HMI) products consist of two parts: hardware and software. The hardware includes a processor, display unit, input unit, communication interface, and data storage unit. The processor's performance determines the overall performance of the HMI product and is its core component. Depending on the product level, 8-bit, 16-bit, or 32-bit processors can be selected. HMI software generally consists of two parts: system software running on the HMI hardware and screen configuration software (such as JB-HMI screen configuration software) running on a PC with a Windows operating system. Users must first create a "project file" using the HMI screen configuration software, and then download the created "project file" to the HMI's processor for execution via the serial communication port between the PC and the HMI product.
How to use the human-computer interface
Clearly define the monitoring task requirements and select appropriate human-machine interface (HMI) products;
Edit the "project file" on a PC using screen configuration software;
Test and save the edited "project file";
Connect the PC to the HMI hardware and download the "project file" to the HMI;
Connect HMI and industrial controllers (such as PLCs, instruments, etc.) to enable human-machine interaction.
