Edge evaluation: Yes
Signal state 1 or edge Activate reverse travel.
change 0 → 1
The RESU main program CC_RESU.MPF is generated from the traversing blocks recorded in the
RESU-internal block buffer in order to initiate travel back along the contour on the next NC START.
Edge change 1 → 0 Activate forward travel.
The RESU main program CC_RESU.MPF is generated from the traversing blocks recorded in the
RESU-internal block buffer in order to initiate travel forwards along the contour on the next NC
START.
Signal state 0 Not relevant.

Activate mirroring
Signal(s) updated:
Mirroring active (1:-1)
1:1 coupling active
Relevant only if coupling is active (DBX97.1 = 1)
Displayed only for the CC_Slave axis.
Offset after point of activation
Signal(s) updated:
New offset after point of activation.
This bit is set to 1 if a particular event (SW/HW limit switch on CC_Slave axis) causes a change
in the offset between CC_Master and CC_Slave stored when the coupling was activated.
No new offset since activation.
The bit is not set in the RESET phase.
Displayed only for the CC_Slave axis.
