2.16 Suppress individual block (SBLOF, SBLON)
2.16
Function
Program-specific single block suppression
For all single block types, the programs marked with SBLOF are executed in their entirety
like one block. SBLOF is written in the PROC line and is valid until the end of the subroutine
or until it is aborted. At the return command, the decision is made whether to stop at the end
of the subroutine.
Return jump with M17: Stop at the end of the subroutine
Return jump with RET: No stop at the end of the subroutine
SBLOF is also valid in subroutines, which are called.
Example for subroutine without stop in single block:
PROC EXAMPLE SBLOF
G1 X10
RET
Programming
PROC ... SBLOF
SBLON
Single block suppression in the program
SBLOF must be alone in a block. Single block is deactivated after this block until
• the next SBLON or
• the end of the active subroutine level.
Parameters
SBLOF
SBLON
Example: single block suppression in the program
N10 G1 X100 F1000
N20 SBLOF
N30 Y20
N40 M100
N50 R10=90
N60 SBLON
N70 M110
N80 ...
The area between N20 and N60 is executed as one step in single block mode.
