Najjednostavnija definicija ljudskog-mašinskog interfejsa ekrana osetljivog na dodir je da između ljudi i mašina, preko određenog interfejsa, ljudi mogu davati uputstva mašinama i opremi, a mašine i oprema mogu da povrate status izvršenja i status sistema na korisnika preko ovog interfejsa. Drugim riječima, ispravna komunikacija informacija i instrukcija između čovjeka i mašine je glavna definicija čovjek-mašinskog interfejsa.
Interfejs čovjeka{0}}mašine može se povezati na industrijsku kontrolnu opremu kao što su programabilni logički kontroleri (PLC), frekventni pretvarači, DC kontroleri brzine, brojila, itd., koristeći ekran za prikaz i upisivanje radnih parametara putem ulaza jedinice (kao što su ekran osetljiv na dodir, tastatura, miš, itd.) Ili unesite komande za ljudske operacije da biste ostvarili interakciju informacija između opreme ljudi i mašina. Ljudsko{1}}mašinski interfejs se sastoji od hardvera i softvera.
Ljudsko{0}}Mašinsko sučelje (Human-Machine Interface, HMI) je polje koje pokriva više tehnologija, uključujući inženjering ljudskih faktora, ergonomiju, računarstvo, umjetnu inteligenciju, kognitivnu psihologiju, filozofiju, sociologiju i antropologiju Discipline kao što su dizajn, dizajn i inženjering ne mogu se u potpunosti promatrati i istraživati iz perspektive IT tehnologije. Čak i među njima, važnost kognitivne psihologije može biti važnija od kompjuterske nauke.
Strictly speaking, the man-machine interface is essentially different from the "touch screen" that people often call. Because the "touch screen" is only the hardware part that may be used in human-machine interface products, it is an input device that replaces some of the functions of the mouse and keyboard and is installed in the front of the display screen. The human-machine interface product is a human-computer interaction device that includes hardware and software. In industrial applications, people often refer to man-machine interface products with touch input function as "touch screen" for short, but this is unscientific. A man-machine interface with touch input function should be called "touch man-machine interface".
Human-machine interface products include hardware and corresponding dedicated screen configuration software. Generally, different manufacturers' human-machine interface hardware use different screen configuration software, and the main connected device is PLC. The configuration software is a general-purpose tool software product that runs on the PC hardware platform and Windows operating system. The configuration software and PC or industrial computer can also be used as a computer interface product. The universal configuration software supports a wide range of equipment types, such as various PLCs, PC boards, meters, inverters, modules and other equipment, and because of the powerful performance of the PC hardware platform (mainly reflected in the speed and storage capacity), it is universal The function of the configuration software is also much stronger, suitable for large-scale monitoring systems.
