The replacement subprogram is provided with all of the information relevant to the functions programmed in the
block (T or TCA, D or DL, M) via system variables.
Exception
D or DL number is not transferred if:

• MD22550 $MC_TOOL_CHANGE_MODE = 1
AND
• D or DL together with T or M function programmed in a block
Parameterization Meaning
MD22550 $MC_TOOL_CHANGE_MODE = 0 Tool change with T function
MD10717 $MN_T_NO_FCT_CYCLE_NAME = "MY_T_CYCLE" Name of the subprogram to
replace the T function
MD10719 $MN_T_NO_FCT_CYCLE_MODE = 0 Call time: End of block
