Assignment of the function keys of predecessor device on Comfort HMI device  
When replacing the HMI devices, the function key assignments are imported from the 
predecessor device to the Comfort HMI device according to the following rules: 
 
Rule  Effect  Measure 
The assignment of an old 
function key is transferred to the 
function key at the same 
position relative to the display of 
the Comfort HMI device. 
The functions can be assigned 
different numbers on the 
Comfort HMI device. 
If necessary, edit the description 
of the soft key assignment in the 
plant documentation. 
The assignment of K keys is 
not
 
transferred. 
The functions of the K keys are 
deleted. 
Before you replace the 
predecessor device, create a 
button for each assigned K key. 
Then copy the function list of the 
K keys to the buttons. Copy the 
function list to free function keys 
after migration. 
Programmed LED functions are 
transferred to corresponding 
function keys at the same 
position on the Comfort HMI 
device.
