HMI is an abbreviation for Human Machine Interface. It is used to effectively control equipment and make decisions based on machine feedback. An HMI can be a simple display screen directly mounted on a machine for factory automation, or a multi-touch display panel that controls an entire production line.
Components of HMI (Human Machine Interface)
Human-machine interface (HMI) products consist of two parts: hardware and software. The hardware part includes a processor, display unit, input unit, communication interface, data storage unit, etc. Among them, the performance of the processor determines the performance level of the HMI product and is the core unit of the HMI.
HMI (Human Machine Interface) Classification
Depending on the product level of the HMI, 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 running on a PC with a Windows operating system. Users must first create a "project file" using the HMI's 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.
Basic Functions and Selection Criteria of HMI Human-Machine Interface Products
1) Equipment operating status display;
2) Data and text input operations, and printing output;
3) Production formula storage and equipment production data recording;
4) Simple logic and numerical operations;
5) It can connect to a network of various industrial control devices.
