preparation command.
Bit 11=1: The tool preparation command (PLC command numbers=2, 4, 5) is also
executed if the same tool preparation command has already been executed.
(Commands 4, 5 contain the tool preparation)
Example: (Tool changed with M6 (PLC command no.= 3):
T="Tool1"; tool preparation
M6; tool change
T="Tool2" ; 1st tool preparation after M6 (for same tool holder)
; is always output to PLC.
T="Tool2"; 2nd tool preparation is only output as a command to the PLC if bit
11 = 1.
; This tool preparation counts as the first if the state of the tool has
changed since the previous tool preparation such that it would no longer be
serviceable.
That might be, for example, an asynchronous unloading of the tool. This tool
preparation then attempts to select a replacement tool.
Bit 11=0: The preparation command can only be output once for any one tool.
Bit 12 to bit 14
Bit 12=1: The preparation command (PLC command numbers = 2, 4, 5) is also
executed when the tool is already in the spindle/tool holder.
T="Tool1" ; tool preparation
M6; tool change
T="Tool1"; tool is already in the tool holder
; 1st tool preparation after M6 (for the same tool holder)
; is only output to the PLC if bit 12 = 1.
; An unserviceable tool (e.g. disabled because of tool monitoring.) on the
tool holder does not count as being on the tool holder. This tool preparation
then attempts to select a replacement tool.
T="Tool2" ; 2nd tool preparation - the rules of bit 11 apply to the output.
Bit 12=0: The preparation command is not executed if the tool is already in
the spindle.
Bit 13=1: On reset, the commands are retrieved from the diagnostics buffer
and stored in the passive file system (TCTRAxx.MPF under part program) This
file is required by the Hotline.
The tool sequences are only recorded in the the diagnostics buffers of sys-
tems that have adequate memory (NCU572, NCU573)).
Bit 14=1: Reset mode
Tool and offset selection correspond to the settings in MD20110
$MC_RESET_MODE_MASK and MD20112 $MC_START_MODE_MASK.
Bit 14=0: No reset mode
Bit 15 to bit 19
Bit 15=1: No return transport of the tool if there are multiple preparation
commands (Tx->Tx).
Bit 15=0: Return transport of the tool from any defined buffers.
Bit 16=1: T = location number is active
Bit 16=0: T="Tool name"
Bit 17=1: Tool life decrementation can be started and stopped via the PLC in
channel DB 2.1...DBx 1.3.
Bit 18=1: Activation of monitoring of "Last tool in the tool group"
Bit 18 Lengthens the search for a suitable tool, above all, when there are a
large number of disabled replacement tools.
