The interface between a process and its operators
About
HMI (Human Machine Interface) is the interface between a processor system and its operators; essentially, it is an operator dashboard. Accordingly, key tool operators and line supervisors use HMI solutions to coordinate and control industrial and manufacturing processes and machines.
An HMI can take complex process variables and convert them into actionable information. It also displays near-real-time operational information. Visual process graphics give meaning and context to motor and valve status, tank levels, and other process parameters. HMIs provide operational insight into the process and support control and optimization by adjusting production and process targets.
The purpose of an HMI is to display real-time operational information in an easy-to-understand way. Visual process graphics give meaning and context to motor and valve status, tank levels, pressure, vibration, and other process parameters. With HMI software, you can control and optimize processes by adjusting production and process targets.
HMIs also provide historical and trend data on machine efficiency or product quality, helping managers and supervisors improve processes. Thus, the flexibility and enhanced capabilities of today's HMI software offer new opportunities to improve machine and process efficiency.
