Graphical HMI Devices

The HMI or Human Machine Interface allows operators to "interface" with the system they oversee. It provides a visual overview of the automated system's status and direct control of its operation. An HMI's graphical screens can be programmed to display important status and control information to the operator. Pictures, icons, sounds, and colors can all be used by HMIs to represent different operating conditions and many HMIs deploy touch screen technology for user interaction with elements displayed on the screen. 

Some of the benefits/features HMIs provide are:

• Line/Bar graphs - display real-time process values over time with line graphs or in easy-to-read bar graphs
• Data entry - easily change process variables with a pop-up numeric keypad on the screen or with increment/ decrement arrows
• Alarming - see fault indications with detailed descriptions that aid in troubleshooting
• Recipe functions - change numerous operating parameters with one click; recipe buttons transfer multiple values from PLC source registers to PLC destination registers and/or from the recipe table to PLC destination registers
• Communication - HMIs also provide communication channels for easy upload/download of programs, PLC communication, and industrial networking
• Advanced features - more advanced HMIs can also provide email capability so the HMI can email important data to you, web server functionality so you can log on to the HMI from anywhere in the world, data logging so you can record production data for future reference, and mobile apps for your smartphone so you can check on production while on the go
• Easy modifications - adding or removing objects, like buttons, on the screen takes no time at all and doesn't cost extra
