DBX33.6 Transformation active
Edge evaluation: no
Signal state 1 or The NC command TRAORI (activate transformation) is programmed in the NC part program. This
edge change block has been processed by the NC and the transformation is now activated.
0 → 1
Signal state 0 or No transformation active.

DBX33.7 Program test active
Edge evaluation: no
Signal state 1 or Program control program test is active. Axis disable is set internally for all axes (not spindles).
edge change Therefore the machine axes do not move when a part program block or a part program is being
0 → 1 processed. The axis movements are simulated on the operator interface with changing axis position
values.
The axis position values for the display are generated from the calculated setpoints.
The part program is processed in the normal way.
Signal state 0 or Program control "Program test" is not active.

The M02 and M30 functions have equal priority.
The interface signal:
DB21, ... DBX33.5 (M02/M30 active)
is available as steady-state signal after the end of the program.
Not suitable for automatic follow-on functions such as workpiece counting, bar feed, etc.
M02/M30 must be written in a separate block and the word M02/M30 or the decoded M signal
used for these functions.
Auxiliary functions that could result in a read-in operation being stopped and any S values that
are to be operative beyond M02/M30must not be written in the last block of a program.
