SIMATIC HMI Key Panels can be used for creating conventional keypad operator panels according to the principle of" plug and control": They are ready for installation and pre-assembled. In this way, time-consuming individual assembly and wiring, as required for conventional operator panels, is not necessary.
This reduces the time required for wiring by up to 90%compared to conventional wiring. All that is required is the corresponding installation cutout and a bus cable for connection to the controller.
