Activation
The function is activated through the PLC basic program via the interface signal:
DB21, ... DBX0.4 (activate single block)
Display
Active single block mode is indicated by a reversal in the relevant field in the status line on the operator interface.
Because of the single block mode, as soon as the part program processing has processed a part program block,
the following interface signal is set:
DB21, ... DBX35.3 (program status interrupted)
Processing without single block stop
Despite the selected single block mode, a processing without the single block stop can be set for specific
program runs, e.g. for:
• internal ASUBs
• User ASUBs
• Intermediate blocks
• Block search group blocks (action blocks)
• Init blocks
• Subroutines with DISPLOF
• Non­reorganizable blocks
• Non­repositionable blocks
• Reposition block without travel information
• Tool approach block.
The setting is done via the following machine data:
MD10702 $MN_IGNORE_SINGLEBLOCK_MASK (Prevent single block stop)
