Modern HMI devices are extremely innovative, capable of higher capacity and more interactive, elaborateįunctions than ever before. The graphical interface contains colorĬoding that allows for easy identification (for example: red for trouble), as well as pictures and icons which allow forįast recognition, easing the problems of language barriers.īecause HMIs increase system efficiency, they can reduce production costs, which could potentially increase profit The greatest advantage of an HMI is the user-friendliness of the graphical interface. HMI provides a display of received inputs, control process outputs, and defined user variables being leveraged to perform the tasks. While these inputs and processes are being performed, the
The PLC takes the information from inputs (physical sensors or commandsįrom the HMI) and transforms it to processes for manufacturing. Logic Controller (PLC) which acts as the CPU.
With an HMI, it must first be working with a Programmable For a manufacturing line to be integrated

So that users can update system processes without changing any of the hardware. (CPU), and may be equipped with data recipes, event logging, video feed, and event triggering, In manufacturing lines, HMIs have can monitor and control processes outside of a Central Processing Unit Productivity by providing a centralized display of the control process that is extremely user-friendly. In the context of manufacturing and process control systems,Īn HMI provides a visual representation of the control system, and provides real time data acquisition. Tasks without the need for an attendant, teller, or other employee. Gas station pumps, self-service kiosks,ĪTM machines, and self checkout lines all use HMIs to process user inputs, convert them to machine readable code, and perform Known as Man Machine Interface (MMI), Operator Interface Terminal (OIT), Local Operator Interface (LOI), Operator Terminal (OT),īut for the purposes of this guide we will refer to them as HMIs.Īn HMI is exactly what the name implies: a graphical interface that allows human users to interact with a system's machinery.Īs technology develops, HMIs are becoming more abundant in everyday tasks for consumers. "HMI" stands for Human Machine Interface.
