HMI screen examples with Allen Bradley Panel builder

What is an HMI and what does HMI stand for?

HMI stands for Human machine interface. HMI's are used as an operator control panel instead of using an excessive amount of hardware and also provides almost unlimited control and status of a fully automated machine cell.

Benefits of an HMI system

1. Takes the place of Physical push buttons
2. Eliminates excesive wiring by interlinking directly into the PLC
3. Easily reprogrammable to add almost any function that exists currently in the PLC without extra wiring or design changes
4. Clear customizable HMI status screens for easier troubleshooting and to save on downtime
5. Almost unlimited functions
6. Alarm control HMI
7. Counter
8. Lock specific people out of performing certain functions
9. Display PLC numeric data
10. Upload pictures for clarification
11. Easy cell duplication
12. Easy cell operation capability from a central device
13. HMI can connect to multiple PLC's within the cell for complete cell status

Below is several screen shots of various HMI status screens that are extremely helpful to have included on all your CNC automation projects screens for CNC interfaces and other machinery and equipment.
