SBLOF in the program
SBLOF alone must remain in the block. Single-block stop is deactivated from this block
onwards up to the next programmedSBLON or up to the end of the active subroutine level.
If SBLOF is active, then this definition is also valid in the called subroutines. SBLON
Example for an area in single block mode
The area between N20 and N60 is executed as one step in single-block mode.
N10 G1 X100 F1000
N20 SBLOF
; Deactivate single block
N30 Y20
N40 M100
N50 R10=90
N60 SBLON
; Reactivate single block
N70 M110
N80 ...
Asynchronous subprograms
The asynchronous subroutines ASUP1.SYF and ASUP2.SYF started system-internally in
REORG/REPOS can process the system ASUP in one step through the programming of
SBLOF.
Example: ASUP.SPF:
N10 SBLOF
N20 IF $AC_ASUP==’H200’
N30 RET
; No REPOS on mode change
N40 ELSE
N50 REPOSA
; REPOS in all other cases
N60 ENDIF
N70 RET
Constraints
• The current block display can be suppressed in cycles with DISPLOF.
• IfDISPLOF is programmed together withSBLOF, then the cycle call continues to be
displayed on single-block stops within the cycle.
• The preset behavior of asynchronous subroutines in single block mode specified in
MD20117 MC_IGNORE_SINGLEBLOCK_ASUP (process interrupt program fully despite
single block) can be overwritten on a program-specific basis using SBLOF.
