2.11 Subroutine call through NC language replacement
2.11.3.3 Parameter transfer during replacement of tool programming
Rules for parameter transfer
The following basic procedure applies when transferring parameters to the replacement
cycle:
• If one of the above-mentioned replacements is active, then all the information required for
• In a part program line only one of the above-mentioned replacement subroutines can be
• One and the same subroutine can be configured for the replacement of the T, D/DL
Caution
Parameter values
The values passed to the replacement subroutine have not yet been executed and must,
therefore, be programmed again in this subroutine.
182
the tool offset selection (T, D or DL, M function for tool change, address extensions) is
transferred to the replacement subroutine.

(Parameterization of T function replacement). Here, it is possible to configure that the
D/DL addresses need not be transferred to the replacement subroutine.
processed at a time.
In case of multiple replacements of the T, D/DL addresses and the M Function for the call
of the tool change program, only one of the replacement subroutines is always active
even under different names. As described above, all the required parameters for the tool
offset selection are then made available to it. If configured accordingly, the subroutine is
called before and/or after execution of the part program line.
addresses and the M Function for the call of the tool change program. The function to be
replaced can then be determined by querying the system variables.
