Data Backup - Siemens SINUMERIK 840D sl Function Manual

Settable frames G54 to G599
The behavior of the adjustable frames can be set using MD10617
$MN_FRAME_SAVE_MASK.BIT0 :
● BIT0 = 0
Using the subprogram, if only the values of the active adjustable frame are changed using
the system variable $P_IFRAME, but the G functions are kept, then the change is also kept
after the end of the subprogram.
● BIT0 = 1
With the end of the subprogram, the adjustable frame, G function and values, active before
the subprogram call, are reactivated.
Basic frames $P_CHBFR[ ] and $P_NCBFR[ ]
The behavior of the basic frame can be set using MD10617
$MN_FRAME_SAVE_MASK.BIT1:
● BIT1 = 0
If the active basic frame is changed by the subprogram, the change remains effective even
after the end of the subprogram.
● BIT1 = 1
With the end of the subprogram the basic frame which is active before the subroutine call
is reactivated.
Programmable frame
With the end of the subprogram the programmable frame active before the subroutine call is
reactivated.
System frames
If the system frames are changed by the subprogram, the change remains effective even after
the end of the subprogram.

Data backup

Data block _N_CHANx_UFR is used to archive the system frames.
Machine data
MD28082 $MC_MM_SYSTEM_FRAME_MASK
should not have changed between saving and reintroducing the saved system frames. If it
has changed then it is possible that saved system frames could no longer be loaded.
In this case, the loading process triggers an alarm.
Data backup always takes place in accordance with the currently valid geometry axis
assignment, not in accordance with the axis configurations set in the machine data.
