6.2 PLC description
• If this data does not match, then after the acknowledgement data of the PLC has been
checked, it is accepted in the NC data management.
• Acknowledgement of the command in the NC is continued.
Note
If the tool to be loaded at change is transported from the magazine to the tool holder in
multiple individual steps, the PLC acknowledgement number 105 applies.
With the PI command _N_TMMVTL or the analog NC command "MVTOOL", a tool in status
"being changed" cannot be moved.
The following applies for loading, relocating, reloading and positioning: The PLC must not
change the target positions specified by the NC for the NewTool as they have to be identical
with those in the NC.
Example 1
A tool is being prepared and already with the preparation is to be brought into gripper_1
(preparation). The change moves the new tool from gripper_1 to the spindle and moves the old
tool into gripper_2. This completes the change.
The NC command looks like this:
Bring the new tool (T No.6) from magazine_3, location_6 to the spindle and the old tool from the
spindle (9998/1) into magazine_3, location_11.
ID:00000/00000-------- CMD:00002
NewTool:
from M: 00003 P: 00006 to M: 09998 P: 00001 TNo: 00006 Spindle: 00001
OldTool:
from M: 09998 P: 00001 to M: 00003 P: 00011
As a result of this change sequence, this task is not executed like this. When acknowledging, the
PLC program must change the data shown in bold.
There are two options to do this:
Case_1
The PLC synchronously acknowledges the preparation command
ID:00000/00001-------- ACK:00002 St: 00001
NewTool:
from M: 00003 P: 00006 to M: 09998 P: 00002
OldTool:
from M: 09998 P: 00001 to M: 09998 P: 00001
Case_2
The PLC asynchronously transports the prepared tool to the gripper and now synchronously
acknowledges the preparation command to the end.
ID:00000/00001-------- ACK:00008 St: 00001
NewTool:
from M: 00003 P: 00006 to M: 09998 P: 00002

ID:00000/00002-------- ACK:00002 St: 00001
NewTool:

OldTool:
from M: 09998 P: 00001 to M: 09998 P: 00001
In both cases, using the end acknowledgement, the NC checks the tool data acknowledged by
the PLC against the data in the command - and after an internal command assignment, corrects
the command data, in order that additional acknowledgements are made with valid data (new
tool located on 9998/2). The source file ("from") for the old tool and the new tool are managed
by the basic program, a change is not possible.

6.2.5
Simplified acknowledgement of tool management commands
Overview
It is possible to acknowledge tool management commands via the user program with FC8/FC6
or FC7. For the standard acknowledgement with the end status per interface, there is a bit
available within DB71, DB72, DB73 which can be used to acknowledge the command using the
cyclic basic program. For this purpose, acknowledgement bits are defined in DB71, DB72, DB73
in DBW2, which the user program must set to acknowledge an active command for one PLC
cycle. When the acknowledgement bit is set for the pending task, then end acknowledgements
are generated.
The acknowledgement parameters used are described in the following table:
Function

Change with turret

If active commands with fault are to be acknowledged, this can also be realized using the
acknowledgement bit in DBW2. In addition, for the particular task, in DBX(n+1.0) the value 1
must be connected in parallel to set the acknowledgement bit. The acknowledgement
parameters are listed in the following table.

When processing an acknowledgement using the acknowledgement bits, the
acknowledgement bit and also DBX(n+1.0) are automatically reset by the basic program.
Note
Before setting the acknowledgement bit, additional intermediate acknowledgements (with the
status > 100), are realized from the user program via the FC8/FC6 (e.g. re-storing in the gripper).
Relocating
If a tool is relocated from the real magazine into the spindle or to a buffer location,
acknowledgement is with Status_6, i.e. the source location in the real magazine is reserved for
the tool. No tool or offset selection is connected to this.
6.2.6
Diagnostics for communication between NC and PLC
General
Communication between the NC and the PLC can be logged in a file as part of the tool change
procedure.
Note
The diagnostics data is saved with the reset or cancel key.

Precondition
• Bit 13 of MD20310 $MC_TOOL_MANAGEMENT_MASK must be set.
• The trace is a ring buffer (_NTCTRA'xx'MPF, with 'xx' = channel number 01, 02, ...). Free
memory space must be available on the NC for saving the data. The number of files in the file
system must be below the maximum number of files.
• The trace size can be set using the machine data
$MN_TOOL_MANAGEMENT_TRACE_BUFFER_SZ[Index] = number of commands
- Index 0 = buffer size of the IPO trace (prepare, change commands and
acknowledgements, asynchronous transfers).
- Index 1 = buffer size of the preparatory trace (commands and acknowledgements due to
PI services).
The Trace representation with index 0 also assumes the commands and acknowledgements
due to PI services. The trace file with index 1 is then irrelevant.
Example
Milling machine with a chain magazine, a spindle and double gripper (any tool is located on the
spindle)
T="Miller_30mm"
- The tool remains at its location, after positioning the mag-
azine, the preparation is acknowledged with "end"
M06
Step 1 (is acknowledged with Status_105)
- Old tool comes from the spindle into Gripper_1
- New tool comes from the magazine into Gripper_2
Step 2 (is acknowledged with Status_1 (end))
- New tool comes from the Gripper_2 into the spindle
- Old tool comes from the Gripper_1 into the magazine
The recorded trace (TCTRA'xx'_MPF), looks like this:

6.2 PLC description
The ID number is used by the NC to assign acknowledgements. The first number specifies the
command ID of the output command. The second number specifies the command identification
with which the PLC had acknowledged the command.
Definition of command identification: Every command via the tool management interface from
the NC to the PLC is allocated a unique identification number. PLC (the basic program, not the
user program) acknowledges a command with this command number. This means that it is
possible to assign the acknowledged command to the command that was output.
Every NC command (CMD) has the following structure:
1. The command ID (this is incremented at each command output)
2. The command no. (CMD preparation, change, ...)
3. The transport for the tool to be loaded at change (from - to)
4. The internal T No. of the tool to be loaded at change
5. The number of the requesting spindle or tool holder
6. The transport for the tool to be replaced (from - to)
Every PLC acknowledgement (ACK) has the following structure:
1. From the ID No. The ID of the NC is returned + a PLC ID
2. The command no. (NC sends a CMD:00002, PLC responds with an ACK:00002)
3. The acknowledgement status (see FC8/FC6 description)
4. The transport for the tool to be loaded at change (from - to)
5. The transport for the tool to be replaced (from - to)

Transfer block for tool change with turret
All function blocks are described in: /FB1/ P3, Basic PLC Program
Additional PLC services
In addition to the function blocks given above, there are further PLC services available for more
complex requirements on the part of the PLC user program to influence tool management.
These services are possible using FB2, FB3, FB4 and FB7 (read and write variables or PI services).
A description of these function blocks is part of the basic PLC program description. The PI services
(program instances) of the tool management are also described in the basic PLC program
description regarding FB4 and FB7. The tool management variables are described in the lists in
the section on variables.

Internal data block of basic program for tool management.
1. There is a separate interface area in DB71 for each loading point configured in the magazine
configuration. The interface area for loading point 1 generally has the task of loading into the
spindle.
Relocation- and positioning tasks are always handled via loading point_1 (spindle loading
point).
2. DB72 contains a separate interface area for every spindle defined in the tool management
function.
3. A separate interface area is provided in DB73 for each turret of the magazine configuration.
The turret numbers are numbered without any gaps from the lowest up to the highest
magazine number.
4. Data for multitools is available in data blocks DB1071, DB1072 and DB1073 (analog to DB71,
DB72 and DB73 loading and unloading, spindle change positions, turret).
All interfaces are designed for receiving tool-management commands (load, tool change, ...).
Basic program blocks FC6 (multitool), FC7 and FC 8 are used to communicate the current
positions of tools.
One of the interfaces is updated by the NC via the basic program after a command (e.g. by
operating the function "Load" or by part program function "Tool change").
Note
If the configuration is changed (number of spindles, loading/unloading points, number of
magazines and numbers, ...), the PLC must also be adapted.
This happens automatically on the next Power On or when DB4 is changed. On the next restart,
the basic PLC program automatically clears DB71 ... DB73, DB1071 ... 1073, DB74 and creates
the blocks again.

The following sequence is defined:
• Is the magazine description from the NC available (and no entry in DB4)?
This is used and set up accordingly; the magazine description is NOT copied to DB4.
• Is a magazine description available in DB4?
- This is used and the user interface set up accordingly.
This means that the entry in DB4 has priority. This ensures full compatibility.
• If there is neither a magazine description from the NC nor one in DB4, the user interface is set-
up with the maximum configuration (16 interfaces each).

Cancel TM
command
GP -> PLC
The function cancels all pending tool management tasks from the NC (compare NC switch-on).
The NC tool management is reset in a defined manner. This is intended to be a pure
commissioning function. If a command must be cancelled in regular operation, then this is done
using FC8/FC6 and acknowledgement status "3" (negative acknowledgement).
This function enables direct intervention by the operator to, for example, take a tool out of the
gripper where a change is just about to take place, or if there is no acknowledgement from the
PLC program.
Note
Please ensure that the data consistency in the NC is maintained.
Boundary condition
The "Delete pending task" function can be activated only if the NC is in the "Channel not active"
state.

After a revolver has been changed, the user calls block FC7 "TM_REV". The revolver number
corresponding to interface number in DB73 must be specified in parameter "ChgdRevNo" for this
purpose. As this block is called, the associated "Interface active" bit in data block DB73.DBW0 of
FC7 is reset after parameter "Ready" == TRUE is returned.

If the job was executed correctly, "Ready" == 1. The user must then set the parameter "Start" = 0
or no longer call FC7.
Job executed with errors
If the job was executed with errors, parameter "Ready" == 0 and parameter "Error" == 1. The job
must be repeated in the next PLC cycle. Since the parameter "Start" does not need a positive edge
for a subsequent job, "Start" = 1 remains, because the job has not yet been completed. See "Call
example" and "Pulse diagram" below.
Constraints
• Block FC7 may only be started with parameter "Start" = 1 if an activation signal for the
associated interface (DB73.DBW0) for this transfer has been supplied by the tool
management function.
• A cancellation of a transfer, e.g. by a channel reset, is not permitted.
• Parameter "Start" = 1, until parameter "Ready" == 1 or "Error" == 1

Manual turret switching
If the turret is rotated in manual operation, neither a tool change nor an offset selection is
associated with this operation. The first step is the removal of the tool from the tool carrier back
to its location in the turret. An asynchronous transfer must be performed with FC8 (alternative:
FC6). The associated parameter settings are shown below:
TaskIdent = 4
TaskIdentNo = Channel no.
NewToolMag = Magazine no. of the turret
NewToolLoc = Original location of the tool
OldToolMag = Magazine no. of the buffer storage (spindle) = 9998
OldToolLoc = Buffer storage no. of the spindle
Status = 1
If the turret is now turned to any position at which a tool is located, this tool must be activated.
This is done easiest by the new T programming in the part program. However, if this should take
place, for example, at the end of turret switching from the PLC user program, an ASUB must be
started for this purpose. The current turret position must be transferred to the ASUB. Thus the
tool is determined on this location in the ASUB and this is selected.

FC8: TM_TRANS - transfer block for tool management
Function
The user calls this block FC TM-TRANS when the position of the tool or the status of the transfer
operation changes. The parameter "TaskIdent" specifies the transfer job for the block FC8 at the
tool management interface:
• For loading/unloading positions
• For spindle change positions
• For turret change positions as transfer identifier
• Asynchronous transfer
• Asynchronous transfer with location reservation
The interface number is indicated in parameter "TaskIdentNo".
Example for loading point 5:
Parameter "TaskIdent":= 1 and "TaskIdentNo":= 5.
Furthermore, the current tool positions and status data (list of "Status" parameter in the
following text) are also transferred for this transfer function.
Note
FC8 informs the NC of the current positions of the old tool.
The NC knows where the old and the new tool were located until the position change.
In the case of a transfer without a so-called "old tool" (e.g. on loading), the value 0 is assigned
to parameters "OldToolMag", "OldToolLoc".
Block FC TM_TRANS may be started only with "Start" parameter = "TRUE" if an activation signal
for the appropriate interface (DB71, DB72, DB73 in word 0) for this transfer has been supplied
by the tool management function.
When this job is executed correctly, the output parameter "Ready" contains the value TRUE.
The user must then set the "Start" parameter to FALSE or not call the block again.
If the "Ready" parameter = FALSE, the error code in the "Error" parameter must be interpreted
(see Call example FC8 and pulse diagram).
Tool management
Function Manual, 10/2020, 6FC5397-1HP40-0BA1
157
PLC programming
6.3 Signal description of the PLC interface and transfer blocks
If the error code = 0, this job must be repeated in the next PLC cycle (e.g. "Start" remains set to
"TRUE"). This means that the transfer operation has not yet been completed.
If the user assigns a value of less than 100 to the "Status" parameter, the associated interface in
data block DB71 or DB72 or DB73, word 0 is deactivated (process completed). The appropriate
bit for the interface is set to 0 by FC8.
The "Start" parameter does not need a signal edge for a subsequent job. This means that new
parameters can be assigned with "Start = TRUE" immediately when "Ready = TRUE" is received.
Asynchronous transfer
To ensure that changes in the position of a tool are automatically signaled from the PLC to the
tool management (e.g. power failure during an active command or independent changes in the
position by the PLC), FC8 is called with "TaskIdent" = 4 or 5. This call does not require interface
activation by the tool management.
If parameter "TaskIdent" = 5, the tool management reserves the location in addition to changing
the position. The location is only reserved if the tool has been transported from a real magazine
to a buffer storage.
A relevant NC channel must be parameterized in the "TaskIdentNo" parameter.
The previous location of the tool is specified in the parameters "OldToolMag" and "OldToolLoc".
The current location of the tool is specified in the parameters "NewToolMag", "NewToolLoc".
"Status" = 1 must be specified.
With "Status" = 5, the specified tool remains at location "OldToolMag", "OldToolLoc". This location
must be a buffer (e.g. spindle). The real magazine and location must be specified in the
parameters "NewToolMag", "NewToolLoc"; the location is at the position of the buffer. This
procedure must always be used if the tool management is to be informed of the position of a
specific magazine location. This procedure is used for alignment in search strategies.
Supplementary conditions
• A cancellation of a transfer, e.g. by a channel reset, is not permitted.
• Parameter "Start" = 1, until parameter "Ready" == 1 or "Error" == 1

Description
tus
1
The tool management job has been completed.
The parameters "NewToolMag", "NewToolLoc", "OldToolMag", "OldToolLoc" of the FC8 block
should be parameterized to the actual positions of the tools involved. Except in the case of
preparing the change, they are normally the specified target positions of the tools of the asso-
ciated tool management interface, see also "Explanations of the formal parameters".
1. In the case of loading/unloading/reloading, the tool has arrived at the required target
address. If the bit in the interface in DB 71.DBX (n+0).3 "position at loading point" is enabled,
status 1 cannot be used for the function termination. Status 5 must be used for correct
termination.
2. In the case of "Prepare change", the new tool is now available. The tool may, for example,
be positioned in a buffer (gripper). In some cases, the target (magazine, location) of the old
tool has been moved to the tool change position after placement of the new tool in a buffer.
However, the old tool still remains in the spindle. The preparations for a tool change are thus
complete. After this acknowledgement, the "Change" command can be received. The posi-
tions in parameters "NewToolMag", "NewToolLoc", "OldToolMag" and "OldToolLoc" corre-
spond to the current tool positions.
3. In the case of "Change" (spindle or turret), the tools addressed in the interface have now
reached the required target addresses.
The tool change operation is thus completed.
2
The "new" tool cannot be made available
This status is only admissible in conjunction with the "Change tool" command. When this status
is applied, the PLC must be prevented from making a change with the proposed tool. The pro-
posed (new) tool is disabled by the tool management function in the NC. A new command is then
output by the tool management with a duplo tool. The positions in parameters "NewToolMag",
"NewToolLoc", "OldToolMag", and "OldToolLoc" correspond to the original tool positions.
The status is provided as first synchronous acknowledgment. This means that receipt status 2
must be implemented immediately after the tool preparation.
A previous intermediate acknowledgement, e.g. with Status_105, is not permissible.
3
An error has occurred
The tool positions must not have been changed. Any changes to the magazine positions of the
tool that have taken place in the meantime must be notified beforehand, for example, with
status = 105 via FC8 transfer block. Only then will the tool positions be taken into account by the
tool management function.
4
It would be better to position the "old" tool in the magazine position specified in parame-
ters "OldToolMag" and "OldToolLoc"
This status is permissible only in conjunction with preparation for tool change (change into
spindle). The magazine location specified for the "old" tool must be free. Once this status has
been passed to the tool management in the NC, a new preparation command is generated
(Status_4 = final acknowledgment) and output to the DB72, for which the requested magazine
position of the old tool is considered.
No new tool search is performed explicitly, the positions for "NewToolMag" and "NewToolLoc"
are taken from the original preparation command. But this is done only when this position is free.
Parameters "NewToolMag" and "NewToolLoc" are not taken into account.

The operation is complete
The "new" tool is in the position specified in parameters "NewToolMag", "NewToolLoc". In this
case, the specified tool is not really in this position, but is still in the same magazine location.
However, this magazine location has been moved to the position set in the parameters (e.g. tool
change position). This status may be used only for turrets, chain-type magazines and disk mag-
azines. The status enables the tool management function to adjust the current position of a
magazine and to improve the search strategy for subsequent commands. This status is permis-
sible only in conjunction with loading, unloading, and reloading operations and with prepara-
tions for a tool change. The "OldToolMag" and "OldToolLoc" parameters must be parameterized
with the data of a buffer.
• Loading, reloading:
On loading or reloading, a location for the tool is already reserved in the NC. The machine
operator must then insert the tool at the target location. Notice: The location reservation is
canceled when the control system is switched on again.
• Tool-change preparation:
Tool motions still to be executed are not carried out until after the tool has been changed.
• Positioning to the loading point:
If the bit in the interface in DB 71.DBX (n+0).3 "position at loading point" is enabled, only
status 5 be used for the function termination (not status 1).
6
The tool management job has been completed
This status has the same function as status 1, but, in addition, a reservation of the source
location is carried out. This status is only permitted when reloading. The command is ended and
the source location of the tool is reserved if the target location is in a buffer magazine.
7
Initiate repetition of the command "Prepare Tool"
This status is only admissible in conjunction with the "Change tool" command. This status is
intended for use when the "new" tool has changed its position (e.g. via an asynchronous com-
mand of the "new" tool). After "Ready = 1" has been provided by FC8, the "Prepare Change"
command is repeated automatically with the same tool. For the automatic repetition, a new tool
search is carried out. The positions in parameters "NewToolMag", "NewToolLoc", "OldToolMag",
and "OldToolLoc" correspond to the original tool positions.
The status is provided as first synchronous acknowledgment. This means that receipt status 7
must be implemented immediately after the tool preparation.
A previous intermediate acknowledgement, e.g. with Status_105, is not permissible.
103
The "new" tool can be inserted
This status is permitted only in the tool change preparation, when the PLC may reject the new
tool (e.g. in case of MD20310 $MC_TOOL_MANAGEMENT_MASK, bit 4 = 1 for the possibility,
request changed parameter from PLC once again). The tool positions have remained unchanged.
This status is therefore necessary, when the processing is to be continued in the NC without an
unnecessary stop.

104
The "new" tool is in the position specified in parameters "NewToolMag", "NewToolLoc"
This status is only permissible if the tool is still in the magazine in the same location. The "old"
tool is in the position (buffer) specified in parameters "OldToolMag", "OldToolLoc". In this case,
however, the new tool is not really in this position, but is still in the same magazine location.
However, this magazine location has been moved to the position set in the parameters (e.g. tool
change position). This status may be used only in conjunction with turrets, chaintype magazines
and disk magazines for the "Tool change preparation" phase. The status enables the tool man-
agement to adjust the current position of a magazine and to improve the search strategy for
subsequent commands.
105
The specified buffer location has been reached by all tools involved
Standard case if the operation has not yet been completed.
The tools are in the specified tool positions (parameters "NewToolMag", "NewToolLoc", "Old-
ToolMag", "OldToolLoc").
Status definition
A general rule for the acknowledgement status is that the status information 1 to 7 leads to the
termination of the command. If FC8 receives a status information, the "Interface active bit" of
the interface specified in FC8 is reset to "0" (see also interface lists DB 71 to DB 73), thus
completing the operation. The behavior is different in the case of status information 103 to 105.
When the FC8 receives a status information, the "Interface active bit" of this interface remains
at "1". Further processing is required by the user program in the PLC (e.g. continuation of
magazine positioning). This status information is generally used to transfer changes in position
of one or both tools while the operation is still in progress.

Overview of OPI and system variables
Fundamentals
All the data required for the purpose of tool management (e.g. to define a magazine or load a
tool...) is stored in the NC. This data can be read and written via part programs with system
variables and via the PLC with FB2 and FB3. When configuring the machine, the user (machine
manufacturer) must determine the most efficient method of reading and writing tool
management data, i.e. in the PLC, the NC or in an ASUP.
Read and write access can generally be made to system variables.
When language commands are used, it may be necessary to program the "STOPRE" command.
The $TC variables do not generate a preprocessing stop.
Tool identifiers can consist of the following characters:
a...z
A...Z
0...9
+ - _ . ,
The names are case-sensitive, i.e. uppercase and lowercase characters are considered different
characters.
Note
Additional information on OPI variables can be found in the Help file for the NC-VAR selector.
Execution of the commands
The initial writing of data for tools or magazines causes the creation of the corresponding
objects with their default data. Examples include:
• $TC_TP1 creates a tool.
• $TC_MAP1[x] creates a magazine.

Use of the magazine data
Sequence for defining data
The "Assign tool to a magazine location" sequence creates an interdependency between the tool
data and the magazine/magazine location data.
Example:
The tool contains the magazine location type for which it is intended. The magazine type
contains its own magazine location type. If the tool is assigned to the magazine location, as a
rule the location type cannot be changed again as this can cause inconsistencies.
The resulting requirement is for tools and magazines to be loaded by a special routine into the
PLC and that the structure-determining definitions may no longer be changed during the
preparation (these are e.g. magazine dimension, magazine location type, duplo no., tool
name, ...). They do not include: Cutting edge data, magazine location status, tool status, ...

ing the tool search.
$TC_MLSR[0,0] = 0;

Loading data
Because tools are linked to magazines via magazine location parameter $TC_MPP6, the
following rules for correct definition of tools and magazines must be adhered to:
1. Load tool data
2. Load magazine data
3. Load $TC_MPP6 parameters (⇒ places tool in magazine location)
The same sequence is used for data backup.
The grinding data of a tool cannot be written until tool type = "grinding tool" has been defined
for at least one cutting edge.
The distance parameter ($TC_MDPx) and the buffer assignment parameter ($TC_MLSR) cannot
be written until the magazines and their locations have been defined.
Delete data
A tool cannot be deleted while it is still contained in a magazine. The following sequence of
operations must be followed when deleting:
1. Delete the magazine data (this removes tools from the magazine); or remove the tool
explicitly from the magazine.
2. Delete tool data
In addition, a magazine cannot be deleted if it has the state $TC_MAP3[i]= 8 (motion is active).
The delete command is rejected for all magazines even if only one magazine is preventing the
command from being executed.
Note
If a single tool is to be deleted it must first be removed from the magazine location with an
unload operation and then it can be deleted.
Tools that are currently selected cannot be deleted! You can ensure that no tool is selected
beyond a part program by programming T0 before the end of a part program independently of
the settings in the machine data (see MD for selecting tools beyond the end of a program).

Use of the tool and cutting edge data
Overview
If a parameter for a cutting edge, tool or magazine that does not exist is written, a new cutting
edge, tool or magazine is created.
Note
When a tool is created, all the cutting-edge-specific data of cutting edge D1 are created with it.
(DP, DPC, MOP, MOPC are preset to "0".) The grinding-specific tool data ($TC_TG1...) is not
created until one of the tool types ($TC_DP1) 400-499 has been programmed for one of the
cutting edges of the tool.

Deleting data
When deleting, the memory area is deleted and automatically released again.
A tool can only be deleted if it is not active (offset-determining) and is not in a magazine, i.e. it
must have been removed or unloaded.
Note
If tool management is active you must ensure that the tool being deleted is not assigned to a
magazine location ($TC_MPP6). This assignment must be removed before the tool is deleted.
The grinding-specific tool data ($TC_TG1...) is created as soon as one of the tool types ($TC_DP1)
400-499 has been programmed for any of the cutting edges of the tool.
If the tool type is set from the current value taken from the range 400-499 to a value outside this
range, the grinding data memory released again, i.e. the grinding-specific data is lost.

Overview of cutting edge data
This data exists for each cutting edge that is created (D1-D12). Tool management includes the
geometry and user data as well as the optional monitoring data for the cutting edges.
If the cutting edges are created via HMI, the D number is counted up from 1. It is possible to
program the D no. with gaps, e.g. D1, D3, D6 if cutting edges are set up using an NC program.
7.4.2
Cutting edge parameter $TC_DP
$TC_DPx[t,D]
Cutting edge parameters for geometry, technology and tool type.
Parameters:
• x: Parameters 1...25
The maximum value for x is displayed in the OPI variable "numCuttEdgeParams" in block Y.
• t: T number 1...32000
• D: Cutting edge number 1...12 or D number
Depending on the tool type, up to 25 cutting edge parameters can be programmed for each tool
cutting edge.

$TC_DP11
$TC_DP11 contains the identification for the main direction of machining as is defined and
required by the Siemens Cycle950. $TC_DP11 assumes an intermediate position between tool
OEM parameter and NC system variable:
• $TC_DP11 is a tool OEM parameter in so far as NC does not evaluate the contents of the value.
• $TC_DP11 is an NC system variable in so far as when accessing via $P_ADT[ n ], with n=11,
NC is subject to the special values 1, 2, 3, 4 of the tool adapter transformation if TMMG and
the subfunction "Tool adapter" are active. This system parameter property is also used with
the analog OPI block TOT.

Like the T No. is sufficient to identify a tool, a tool is equally unique in terms of its duplo number

Size in terms of half locations:
Size 1 means that the tool exactly completely occupies its own magazine location. If the size
increases in one direction by 1, half an adjacent location is reserved in this direction for the tool.
The maximum programmable size is 11. This means that no more than five whole adjacent
locations can be reserved by the tool in one direction.
The tool size (half locations) can only be written or changed if the tool does not have an owner
location. This applies to the following situations:
• The tool has yet not been loaded
• During loading, as long as the tool is not at its target location in a real magazine
• If the tool is at a location of the buffer or loading magazine and beforehand, the owner
location as well as the reservation in the magazine was deleted (exclusively using the NC
commands DELMRES and DELMOWNER).

The magazine location type can only be written or changed if the tool does not have an owner

• If the tool is at a location of the buffer or loading magazine and beforehand, the owner

7.5 Tool data
$TC_TP8
The tool status is described with system variable $TC_TP8. The system variable is bit-coded. In
other words, a particular state of the tool is assigned to each bit of this data.
The status of a tool must be bit 1=1 ("enabled") so that it can be loaded within the scope of a
programmed tool change for machining in the toolholder.
During tool selection, the status of a tool that is loaded onto the toolholder (spindle, ...) is set by
the NC to bit 0 ("active").
A tool cannot be loaded if its status is bit 2=1 ("disabled"). The status is set automatically by the
tool monitoring function, when the monitoring value of at least one cutting edge reaches the
limit value. The status bit 2=4 of the tool on the toolholder can or will be ignored when
generating the INIT blocks (see MD 20110 and 20112). The PLC also has the option to make NC
ignore the status during tool selection.
The status bit 4=1 ("prewarning") is mainly for information purposes. With this status the tool
can still be loaded.
The status bit 7=1 ("was in use") is set by the NC if the tool is removed from a magazine location
of the type spindle or toolholder.
The tool status bit 5=1 (="W"= is being change) is always reset by the software during buffered
booting. A tool receives/loses this status within the scope of a programmed tool change.
The following applies: All tools (new and old) involved in the tool change are given the status bit
5=1 by the tool selection. The status is reset again by the end acknowledgement for each tool
command.
The following applies in particular:
The end acknowledgement of the PLC command 2 (programming the T address with
$MC_TOOL_CHANGE_MODE=1), resets the status "W" of the old tool.
With the end acknowledgement of the PLC command 3, 4, 5
(programming M06 in a block with $MC_TOOL_CHANGE_MODE=1, T, M06 in a block with
$MC_TOOL_CHANGE_MODE=1
T address with $MC_TOOL_CHANGE_MODE=0)
the status bit 5=1 of the old and the new tool is reset.
Tools that are in the buffer can also be used for a new programmed tool command if they have
the status bit 5=1 (alternating).
Tools that are in the real magazine and have this status can be used depending on bit 21 of the
MD 20310 or cannot be used for a competing tool-change command for another spindle.
The status bit 5=1 is generally not taken into consideration for a tool selection within the scope
of a block search or for init block generation.
For a RESET, the status is reset for those tools that are involved in a tool change at that point in
time.
The status bit 5=1 is not evaluated when a manual tool is selected.
The tool status bit 8=1 ("return transport") ensures that during the next tool change, a tool that
is at a buffer location and not intended for the next job in machining is returned to the real
magazine.
Bit 9 ignores disabled state.

NC programming
7.5 Tool data
If this bit is set, the disabled state of this tool is ignored. This means the disabled tool can be used
(depending on the search strategy).
This state acts independently of the PLC interface signal:
"Tool disable not effective" (DB21.DBx29.7).
Status bit 11 (to be loaded)
Bit 11 is set for tools that are not in a magazine and are to be loaded. The following definitions
apply:
• The state remains for Power On.
• It is included in the data back-up and rewritten when transferred back to the NC.
• When assigning a tool to a real magazine the tool status is reset by the NC (applies to locations
of location type 1, i.e. not to internal magazines such as the loading magazine, buffer
magazine, etc).

Status bit 10 (to be unloaded)
Bit 10 is set for tools that are located in a magazine and are to be unloaded. The following
definitions apply:
• The state remains for Power On.
• It is included in the data back-up and rewritten when transferred back to the NC.
• Unloading a tool via an unloading location causes the NC to reset the tool status.

"To be unloaded"
For $MC_TOOL_CHANGE_ERROR_MODE, Bit 9 = 1:
A tool that has the status "to be unloaded" ($TC_TP8, Bit 10 = 1) is treated like a disabled tool,
i.e. it is no longer taken into consideration during a tool search and can no longer be selected
within the scope of T programming.
Status bit 12 (reserved)
Bit 12 is reserved.
State bit 14 (tool marked for 1:1 exchange)
NC-internal state, that indicates (for a selected search strategy, 1:1 interchange), that the new
and old tool should be interchanged 1:1.
Note
Take care when "manually" changing the tool status via the OPI during machining. This could
undo internal state changes by the NC and result in incorrect machining.
