Caution
For security reasons, it is essential to install the Keyhook tool in the case of units
with a front keyboard.
The program contains two functions:
• Function 1 (only required for WinCC):
The KeyHook tool serves to exchange the keycodes of function keys F13 to F20
and S1 to S16 on a Panel PC 670V2/ 870V2 with front keyboard on which the
WinCC application will be run.

button
• Function 2 (is required for all SIMATIC Panel PCs with front keyboard)
The KeyHook 2.x version involves the installation of a mutual key lock of
function keys F1 to F20 and S1 to S16. If several function keys are pressed
simultaneously, only the function of the key pressed first is activated. All the
other function keys are suppressed.
Programming the keyboard (KEYPAD)
Only for keyfront units:
This tool enables the modification of the assignment of keycodes to individual keys.
After loading the relevant standard table, it is possible to edit the assignment of the
individual keys. The changes made are transferred to the keyboard controller by clicking
on the "Send" switch and saved there in a nonvolatile memory.
