HMI
HMIs (human-machine interfaces) and operator panels cover all the touch or keypad control panels used to operate and monitor your PLCs in real time.
Whether graphic panels, text displays with function keys or spare parts (front bezels, mounting clips), they ensure smooth and precise interaction between operator and machine.
Discover a complete selection of new, refurbished or obsolete HMIs from leading brands (Siemens SIMATIC, Telemecanique Modicon) to repair or extend the life of your control stations.

FAQ
A keypad panel uses physical or pre-programmed function keys for navigation and input, making it particularly suited to very harsh environments where heavy gloves are worn. A touch panel offers a smooth graphical interface configured through touch zones on the screen, making complex supervision of automated lines easier.
Common failures come from a worn touch panel, a failed LCD backlight or a fault on the power/communication board. In many cases, the unit can be repaired at component level, or just the touch panel/front bezel replaced, without buying a complete new unit.
For most ranges (notably Siemens and Telemecanique), the program can be extracted with the original development software (WinCC Flexible, TIA Portal, Magelis) or transferred via memory card/USB stick. Our teams can also help you back up, reload the firmware or migrate to an equivalent part number.
Every panel or screen is fully cleaned, its front sealing is checked, then it is dynamically tested on a bench: touch calibration, function key response, display brightness and validation of the communication ports (MPI, PROFIBUS, Ethernet/PROFINET).
