Program step
Decode single
block
Note
4-24
The block containing the breakpoint (N0005 in the example) is highlighted.
When the block with the breakpoint has been processed, you can interrupt
program execution with PROGRAM STOP. You can continue program
execution with NC START.
Stop at target block (BRK), program step (PST) and decode single block
(DEC) function according to the principle of 1 of 3.
For example, if BRK was active and PST is set to YES, BRK is automatically
reset, etc. You can reset these functions by pressing the PROGRAM
MODIFICATION softkey.
You will find a description of the functions BRK, PST and DEC in the section
entitled "Program modification".
Note
Teach-in is only possible if decoding and processing take place on the same
level. In other words, a program must be interrupted with a decode stop (DSB,
PST, BRK, End) and an advanced decoding (tool radius compensation,
contour definition, etc.) may not be active.
You can use the single block key on the machine control panel to interrupt a
program but you cannot perform a teach-in at this breakpoint (it is not a
decode stop).
