TOOL_MANAGEMENT_MASK
Channel–specific activation of tool management
Bit 13=1: Only for systems with sufficient memory capacity. Recording of
tool sequences in a diagnostics buffer. On reset the commands are transferred
from the diagnostics buffer to the passive file system (NCATR xx.MPF under
part program).
This file is required by the Hotline.
Tool sequences are recorded in the diagnostics buffer only on systems with
sufficient memory (NCU572, NCU573).
Bit 14=1: An automatic tool change takes place on Reset and Start in accordance
with the following machine data
MD 20120 TOOL_RESET_NAME
MD 20110 RESET_MODE_MASK
MD 20124 TOOL_MANAGEMENT_TOOLHOLDER.
If the tool specified in TOOL_RESET_NAME is to be loaded (this is set in
RESET_MODE_MASK), a tool–change command is output to the application
interface on RESET or START (DB72).
If RESET_MODE_MASK is set to retain the active tool and if the active tool is
disabled in the spindle (by the user), a tool–change command for a
replacement tool is output to the application interface.
If no replacement tool is available,
an error message is output.
Bit 14=0: No automatic tool change takes place on RESET and START.
Bit 15=1: The tool is not returned in response to several preparation commands
(Tx–>Tx).
This method of function activation permits various combinations.
Example for default activation of tool management:
MD 20310 TOOL_MANAGEMENT_MASK = 3 (Bit0 + 1 = 1)
Bit16=1: T location number is active
Bit 15=0: The tool is not returned.
Bit 16=1: T=location number is active.
Bit 17=1: Tool life decrementation can be started/stopped via the PLC in channel
DB 2.1...DBx 1.3.
Bit 18=1: Activation of monitoring
"last tool in tool group".
Bit 18=0: No monitoring for "last tool in tool group"
Bit 19=1: Activation for bit 5...8
Bit 19=0: Functions described under bits 5...8 are not available.
Bit 20=0: The commands generated on PLC signal "program testing active" are not
output to the PLC. The NCK acknowledges the commands itself.
Magazine and tool data are not changed. Exception: The status
of the tool activated in the test area can be changed to "active".
Bit 20=1: On PLC signal "program testing active" the commands generated are output
to the PLC. In so doing. depending on the type of PLC acknowledgment,
tool/magazine data in the NCK may be altered. If the acknowledgment
parameters for the target magazine are set with the same values as the source
magazine, the tool is not transported and thus no data is modified in the NCK.
Exception: The status of the tool activated in the test area can be changed to
"active".
Bit 21=0: Ignore tool status "W" on tool selection.
Bit 21=1: Tools with status "W" cannot be selected by another
tool change or tool preparation command.
Bit 22=0 Default setting
Bit 22=1 If the function T="Location" (see Bit 16) is active, the tool groups are
automatically divided into subgroups. $TC_TP11 is the
grouping and selection parameter. On transition to replacement tool
only those tools in the tool group are recognized as replacement tools
that in the $TC_TP11–value have at least one bit of the tool
set to the programmed location.
Bit 23=0 Default setting
Tool management selects the tool in the main run with optimum certainty; i.e.
the interpreter must, if correction is required, wait for the end of tool selection.
Bit 23=1 For single applications
the interpreter selects the tool itself; i.e. if correction is required, no synchron-
ization with the main run is needed. (If after selection but before loading
the tool becomes no longer usable, a non–correctable alarm may result.)
