Restrictions
• 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
• If the single block stop in the system ASUB or the user ASUB is suppressed with Bit0 = 1
• The single block stop in the user ASUB is suppressed with
• By selecting SBL3 you can suppress the SBLOF command.
• Ignore single block stop in the single block type 2. Single block type 2 (SBL2) does not
Single block disable for unsynchronized subroutines
To run an ASUB in single block mode in one step, the ASUB must contain a PROC
statement with SBLOF. This also applies to the function "editable system ASUB" in
MD 11610: ASUP_EDITABLE.
Example of "editable system ASUP":
N10 PROC ASUB1 SBLOF DISPLOF
N20 IF $AC_ASUP=='H200'
N30 RET
N40 ELSE
N50 REPOSA
N60 ENDIF
Program control in single block mode
With the single block function, the user can process a parts program block by block. The
single block function has the following settings:
• SBL1: IPO single block with stop after each machine function block.
• SBL2: Single block with stop after each block.
• SBL3: Stop in the cycle (by selecting SBL3 you can suppress the SBLOF command).
