Block search active
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The block search function is active.
It was selected from the operator interface screen and started using the interface signal:
DB21, ... DBX7.1 (NC start)
Signal state 0 or
edge change
1 → 0
Search target found.

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
