4.8 Transmission of eroding parameters to the PLC
The following PLC markers define the transmission of eroding parameters to the PLC:
Set Reset
M2794 If MP2199 = 0:
a Q-parameter in the range Q90–Q99 has been
changed and the values transferred to the
appropriate addresses in the PLC.
Acknowledgment is by a reset from the PLC.
If MP2199 = 2:
a Q-parameter in the range Q96–Q98 has been
changed and the values transferred to the
appropriate addresses in the PLC.
Acknowledgment is by a reset from the PLC. NC PLC
M2795 If MP2199 = 2:
Values have been changed in editing mode in the
currently active Stage Number of the erosion table
during program run.
Acknowledgment is by a reset from the PLC. NC PLC
M2796 If M2795 has indicated changed values in the
currently active erosion table, M2796 should be set
by the PLC if these new values are to be
transferred immediately to the PLC (B668 and
following). The NC will reset the marker to
acknowledge successful execution. PLC NC
M2798 A new parameter table is active (first CYCL DEF
GENERATOR)
or M36
or eroding parameters displayed in the status during
program run have been changed
or the value of Q99 (Power Stage Number NR) has
been changed if M36 is active.
Acknowledgment is by a reset from the PLC. NC PLC
M2799 Strobe marker for starting transmission to the
