Example 3:
An ASUB, which is started by the PLC in order to activate a modified zero offset and tool
offsets, is to be executed invisibly.
Program code
N100 PROC ZO SBLOF DISPLOF
N110 CASE $P_UIFRNUM OF
N120 _G54: G54 D=$P_TOOL T=$P_TOOLNO
N130 RET
N140 _G54: G55 D=$P_TOOL T=$P_TOOLNO
N150 RET
N160 _G56: G56 D=$P_TOOL T=$P_TOOLNO
N170 RET
N180 _G57: G57 D=$P_TOOL T=$P_TOOLNO
N190 RET
N200 END: D=$P_TOOL T=$P_TOOLNO
N210 RET
Example 4: Is not stopped with MD10702 Bit 12 = 1
Initial situation:
• Single block execution is active.
• MD10702 $MN_IGNORE_SINGLEBLOCK_MASK Bit12 = 1

Comments
; Suppress single block stop:
; Execution is not stopped in the part program line due to
the fact that MD10702 bit12=1.
