2.11.3 Replacement of tool programming
2.11.3.1 T- and D/DL function replacement
Subroutine call via T function and D or DL function
Note
The subroutine call via T function is referred to hereinafter as T function replacement, and
the subroutine call via D or DL function is referred to hereinafter as
D function replacement.
Call rules
If a T function is programmed in a part program block, a machine data can be used to
specify that the subroutine defined in
MD10717 $MN_T_NO_FCT_CYCLE_NAME[n] (name of the tool replacement for T function
replacement) is called at the start or end of the block. Similarly, a replacement subroutine for
the addresses D or DL can be defined with the MD11717
$MN_D_NO_FCT_CYCLE_NAME[n] (UP-name for T function replacement).
The call timing for T and D or DL function replacement can be set with the MD10719
$MN_D_NO_FCT_CYCLE_MODE Bit 1 and Bit 2
(parameterization of T function replacement).
Assigning subroutines
The machine data
• MD10717 $MN_T_NO_FCT_CYCLE_NAME is used to assign a subroutine to the T
command
• MD11717 $MN_D_NO_FCT_CYCLE_NAME is used
to assign a subroutine to the D and DL command. The same subroutine should be
configured for the T and D replacement. The corresponding values are not output, the T-
word and the D or DL word must be programmed again in the cycle.
Boundary condition
The subroutine configured with MD10716 $MN_M_NO_FCT_CYCLE_NAME[n] and with
MD10717 $MN_T_NO_FCT_CYCLE_NAME or MD11717 $MN_D_NO_FCT_CYCLE_NAME
cannot take effect simultaneously in a block (part program line), i.e. no more than one D, T,
or M function replacement (or generally just one subroutine call) may be executed per block.
Conflicts with other subroutine calls are signaled by alarm 14016.
