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 as per
MD20120 TOOL_RESET_NAME
MD20110 RESET_MODE_MASK
MD20124 TOOL_MANAGEMENT_TOOLHOLDER.
If the tool specified in TOOL_RESET_NAME is to be loaded
(this is set in RESET_MODE_MASK), a tool selection and change command is
output to the user interface on RESET or START (DB72).
If RESET_MODE_MASK is set, thus retaining the active tool, and the active
tool is disabled in the spindle (by the user), a tool change command for a
replacement tool is output to the user 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:
MD20310 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 bits 5 to 8
Bit 19=0: Functions described under bits 5 to 8 are not available.
Bit 20=0: On PLC signal "program testing active" the commands generated on 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 -
that in the $TC_TP11–value have at least one bit of the tool-set to the
programmed location are recognized as replacement tools.
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 until 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.)
