DBX32.6 Last action block active
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
The last action block is being executed.
This means, that all the action blocks on the side of NC have been processed and the actions on the
side of PLC (ASUP, FC) or the operator such as overstore, mode change according to JOG/REPOS
are possible. In this way the PLC for example can still perform a tool change before the start of
movement.
Signal state 0 or
edge change
1 → 0
The last action block is not being executed. Action blocks contain the actions collected during "block
search with computation" such as
• outputting help function H, M00, M01, M..
• Tool programming T, D, DL
• Spindle programming S-Value, M3/M4/M5/M19, SPOS
• Feed programming, F

DBX33.5 M02/M30 active
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
• NC block with
M02
or
M30
(or
M17
if a subroutine was started) is completely processed; if
traversing motions are also programmed in this block, the signal is only output when the target
position is reached.
• The program was interrupted as a result of a reset, and the program status changes to
"Aborted".
• When MDA mode or machine functions REF or PRESET are selected
• After DB10 DBX56.2 (acknowledge EMERGENCY STOP)
Signal state 0 or
edge change
1 → 0
• No program end or program abort
• Status after activation of control
• Start of an NC Program
