Operator panel front of 6FC52100DF222AA0 Terminal Keypad
When changing the operator panel front, the existing USB interface and the display support of 6FC5210-0DF22-2AA0 (with display, backlight inverter and keyboard controller) can be reused. They are therefore disassembled and re-assembled after the appropriate component has been replaced. We recommend that the keypad controller of Siemens 6FC5 210-0DF22-2AA0 Membrane Keyboard Keypad is re-used so that the control parameters that have been programmed-in are not lost.
