Configurable call time in D/T function replacement
The time of the call of the replacement subroutine can be parameterized as follows:
MD10719 Bit 1 MD10719 Bit 2 Timing of call of replacement subroutine
0 0 At block end (default)
1 0 At block start
0/1 1 At block start and block end
Timing of call at block end MD10719 Bit 1 = 0
After the replacement subroutine has been executed, the interpretation is resumed with the
subprogram line following the line that triggered the replacement operation.
Timing of call at block start MD10719 Bit 1 = 1 and Bit 2 = 0
After the replacement subroutine has been executed, the part program line that controlled
the call of the subroutine is interpreted. The T address and the D or DL address and the M
function for the tool change are no longer processed.
Timing of the call at block start and at block end M10719 Bit 2 = 1
The replacement program is called twice.
Note
Which replacements are to be performed at the block start and which are to be performed at
the block end is up to the user.
Configuration of transfer of D or DL function to the replacement cycle
The T function replacement permits the use of machine data
MD10719 $MN_T_NO_FCT_CYCLE_MODE (parameterization of T function replacement) for
specifying which of the following are to occur if D or DL and T are programmed
simultaneously in a block (Bit 0)
• D or DL must be passed as a parameter to the T replacement cycle
• A call is to be executed before the T replacement cycle
MD10719 Bit0 Transfer to the replacement subroutine
0 D or DL number is transferred to the cycle via a system variable
(default value)
1 D or DL number is calculated directly in the block. This function is active only if the
tool change has been configured with M function, otherwise the D or DL values are
always transferred. *
*Tool change with M function is configured with
MD22550 $MC_TOOL_CHANGE_MODE = 1 (tool change with M function).
