A1/ ESC touch function

XBTP: when you are in a page and you came here without using a link to page, then pressing on ESC does nothing.
XBTR: pressing on ESC causes to go back to the previous page, or to the default page.

Consequently: the PLC program needs to take in account this difference.

The display of alarmhistorical occurs differently
- XBTP : history is simply displayed
- XBTN/R: you need to enter to the alarm to display the history

A3/ Function touch:

XBTP: while a F touch is maintained pressed, the rest of the keyboard remains active
XBTN/R: while a F touch is maintained pressed, the rest of the keyboard remains inactive

A4/ Image of function keys
- For the XBT-H/P/E range, when a function key is linked to a page access, the corresponding bit of the "image of function keys" word is set to 1.
- For the XBT-N/R range, when a function key is linked to a page access, the corresponding bit of the "image of function keys" word keeps unchanged.
