2.11.4 Parameter transfer to the replacement subroutine
Rules for parameter transfer
The following basic procedure applies when transferring parameters to the replacement
cycle:
• If on of the replacements indicated above is active, all information required for the tool or
• Only one of the replacement subroutines indicated above can be executed in a part

offset selection (T, D or DL, M function for tool change, address extensions) is forwarded
to the replacement subroutine.

configure that the D/DL addresses not be transferred to the replacement subroutine.
program line.
If there are multiple replacements of the T or D/DL address and the M function for the call
of the tool change program, only one of the replacement subroutines is ever active even if
their names are different. The, as described above, all necessary parameters for the tool
offset or tool offset selection are made available. If configured accordingly, the subroutine
is called before and/or after execution of the part program line.
2.11 Subroutine call with M, T, and D functions
; Replacement subroutine
Scan whether address T has been
programmed
; Replacement for address T with tool no.
; Move revolver to indexing position
; Select tool (T selection)
; Scan whether address D has been
programmed
; Replacement for address D
; Select offset (D selection)
; Scan whether address DL has been
programmed
; Rest of N410 without tool programming
