The concept of man-machine interface oled modules

The definition of the man-machine interface products
Connected to the programmable logic controller (PLC), inverter, DC converter, instrumentation and industrial control equipment, the use of the display through the input unit (such as a touch screen, keyboard, mouse, etc.) written to the operating parameters or input operation command, man and machine information exchange digital device, composed of both hardware and software. HMI is the abbreviation of the English Human-Machine interface.

Composition and working principle of man-machine interface (HMI) products
HMI products offered by the hardware and software components, part of the hardware including the processor, display unit, an input unit, communication interface, data storage unit, wherein the performance of the processor determines the performance level of the HMI HMI core unit. According to the different level of HMI products, the processor can use 8-bit, 16-bit, 32-bit processor. HMI software is generally divided into two parts, namely running on the HMI hardware, system software and operating system running on the PC Windows screen configuration software (such as JB-HMI screen configuration software). The user must first use the the HMI screen configuration software production "project file", and then through the serial communication port of the PC and HMI products, the preparation of the project file downloaded to the HMI processor running.
