Output Suppression Of Spindle-Specific Auxiliary Functions - Siemens SINUMERIK 840D sl Function Manual

During block searches, the auxiliary functions are collected on the basis of specific groups.
The last auxiliary function in an auxiliary function group is output to the PLC following a block
search:
● Group 5: M7
● Group 6: M9
If they are output in the sequence M7 → M9, no coolant is then active. However, coolant 2
would be active during the execution of the program. Therefore, the correct output sequence
for the M auxiliary functions is determined with an ASUP which contains the predefined
procedure AUXFUMSEQ(...):
Program code
DEF INT _I, _M_IN[3], _EXT_IN[3], _NUM_OUT, _M_OUT[2], _EXT_OUT[2]
_M_IN[0]=7 _EXT_IN[0]=0
_M_IN[1]=8 _EXT_IN[1]=0
_M_IN[2]=9 _EXT_IN[2]=0
AUXFUMSEQ(3,_M_IN,_EXT_IN,_NUM_OUT,_M_OUT,_EXT_OUT)
FOR _I = 0 TO _NUM_OUT-1
ENDFOR

Output suppression of spindle-specific auxiliary functions

Function
In certain situations, such as a tool change, it may be necessary not to output the spindle-
specific auxiliary functions collected during the block search in action blocks, but to delay
output, for example, until after a tool change. The automatic output of the spindle-specific
auxiliary functions after a block search may be suppressed for this purpose. Output can then
be performed manually later by overstoring or by an ASUB.
Parameterization
Suppression of the automatic output of the spindle-specific auxiliary functions after a block
search is set via machine data:
