Selection of single block type
An operator input in the Program control area on the HMI specifies the single block type.
Activation
On detection of the "Single Block" key on the machine control panel, the basic PLC program
sets interface signal:
DB21, ... DBX0.4
to activate the single block function.
If there is no machine control panel available, HMI Embedded can be used to activate the
"Single block" key in the machine area with the same result.
In the case of HMI Advanced without machine control panel, a user display must be
configured with a suitable softkey that sets/resets interface signal:
DB21, ... DBX0.4.
Display
Active single block mode is indicated by a reversal in the relevant field in the status line on
the operator interface.
As soon as the part program execution has processed a part program block in single-block
mode, interface signal:
DB21, ...DBX35.3 (program status interrupted)
is set.
Control options
For certain sequences, continuous program execution can be desirable despite the selection
of single-block mode.
Machine data:
MD10702 $MN_IGNORE_SINGLEBLOCK_MASK
specifies which operations are to be processed without interruption.
• Internal ASUPs
• 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.
Assignments between operations and bits of the machine data can be found in the machine
data description.
