Activating user softkeys

A total of 16 user softkeys are available on HT 8. The user softkeys are without any function
by default. The functionality of the user softkeys must be implemented by the user (machine
manufacturer) in the PLC user program. Hence, it is the sole responsibility of the user
(machine manufacturer) to undertake any required interlockings for the activation or
coordination in the process sequence of user functions as compared to other user functions
or default functions.
Display of the user softkeys in the input data area
