Detailed Description
2.8 Single block
Mode Group, Channel, Program Operation, Reset Response (K1)
Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2-117
In the program
SBLOF must be alone in a block. With effect from this block, single-block stop is deactivated
until the next programmed SBLON or until the end of the active subroutine level.
If SBLOF is active, this also applies in subroutines, which are called.
Area
Example: 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 system-internal asynchronous subroutines ASUP1.SYF and ASUP2.SYF, started via
Reorg/Repos, can process the system ASUB in one step via programming of SBLOF.
ASUB.SPF
Example: ASUB.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
Boundary conditions
• The current block display can be suppressed in cycles using DISPLOF.
• If DISPLOF is programmed together with SBLOF, 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 can be overwritten on a program-
specific basis using SBLOF.
