2.4.3 Program control display
Function
Functions that have been activated are visible in the program control
display (can be set via "Program control", see Subsection 4.6.12). The
functions are displayed irrespective of the selected menu.
SKP
Skip block
Program blocks in which the block number is preceded by a slash are
skipped when you run the program (e.g. "/N100 ..."). Up to 10 program
levels can be hidden (e.g., "/6N100 .."; the 7th program level is
hidden)

SBL1
Single block with STOP after
each machine function block
If this function is active, execution is interrupted after every block that
triggers a function on the machine
(calculation blocks do not cause an interruption).
SBL2
Single block with stop after
each block
If this function is active, the part program blocks are executed as
follows: Each block is decoded separately and execution is interrupted
after every block.
SBL3
Stop in cycle
If this function is active, the part program blocks are executed
individually in the cycle as follows:
Each block is decoded separately and execution is interrupted after
every block. Part program blocks are
- Traversing blocks
- Switching and auxiliary functions
- Blocks generated internally in the controller (e.g. blocks inserted
for tool radius compensation)
- Thread blocks after retraction
- Thread blocks with dry run feedrate
Thread blocks without dry run feedrate are an exception to this. In
such blocks, a stop is only performed at the end of the current thread
block. SBL2 can only be selected in the Reset state.
Either SBL1 or SBL2 can be selected!
This function can be activated only in the "Single block" state.
