7.5 Tool data

Status bit 17 (tool is at a disabled magazine location)

Tools in a subsequently disabled magazine location are assigned, with $TC_TP8 Bit 17=1, the

identifier indicating that they are located in a disabled magazine location. With instruction

$TC_MPP6, tools identified in this way can be placed in disabled magazine locations or disabled

adjacent locations. Oversize tools that project beyond the edge of the magazine are not taken

into account.

$TC_TP9

If a monitoring type is activated for the tool with $TC_DP9, the current monitoring parameters

are evaluated and, if necessary, the tool status set to "disabled" or "prewarning limit reached". An

existing tool disable is however not withdrawn. Not even then when the monitoring function for

this tool has been deactivated.

$TC_TP11

Tool subgroups

The system variable is bit-coded. Only bits 0...3 are evaluated. A tool group (the same identifier,

different duplo No.) can be split into a maximum of 4 subgroups in this way. A tool can also be

included in several subgroups.

If no bit is set, so $TC_TP11[x]=0, this means the same as "all bits set", i.e. the tool belongs to all

the defined subgroups.

Selection of the tool subgroup

1. With the NC command $P_USEKT (UseKindofTool)

(only possible when not working with the setting T=location)

During tool search, only tools that have one of these bits in system variable $TC_TP11, can

be found. This means that it is possible to form so-called "Technology Groups", to

differentiate between tools with the same identifier and specifically release them for

machining.

Example 1:

$P_USEKT=4

This means that the only tools to be taken into account are those with bit 2 in $TC_TP11 or

Example 2:

$P_USEKT=9

This means that the only tools to be taken into account are those with bit 3 or 0 in $TC_TP11

2. By programming a tool

with the function T=location $P_USEKT is set automatically at every tool change and in fact

at the $TC_TP11 value of the loaded tool.

Example: T3 M06

The bit value of $TC_TP11 of T3 is now valid (is accepted in "USEKT").

During the transition to a spare tool (and there only) the only tools to be taken into account

are those with one of these bits set in system variable $TC_TP11.

Technology-specific grinding data

The default setting for grinding data is "0". Tools with tool type 400 to 499 are always grinding

tools, i.e. additionally have these data which take up additional memory space. If a tool of type

400-499 is set to a value outside this range, then its loses its grinding-specific data - the

associated memory is released again and can be used for other tools.

7.6 Magazine data

$TC_MAP3

The magazine status bit 3 (tool motion is active) is always reset when the software is booted with

backup.

A magazine that has the status "Tool motion is active" cannot be deleted.

Empty locations are not sought in magazines with the "disabled" status. If a disabled magazine

is explicitly defined for the empty location search, then the process is aborted with an error

message.

A tool that is in a "disabled" magazine cannot be loaded into the spindle or the tool holder.

Overlapping edge locations (bit 8...11=1)

For default setting (Bit 8 ...11 = 0), an oversized tool extends beyond the magazine edge

locations. If this has to be prevented (e.g. due to the mechanical situation at the machine), then

one or several of these bits can be set.

Example: Bits 8 and 9 are set, bits 10 and 11 are not set.

This means that an oversized tool must not overlap the magazine (typically a box-type

magazine) on its left and right sides, but an oversized tool may overlap / extend beyond the

magazine on its top and bottom sides.

The following applies:

Left and top regarding a reference location is where the magazine locations with the lower

magazine numbers are.

Right and bottom regarding a reference location is where the magazine locations with the

higher magazine numbers are.

$TC_MAP8

The current magazine position $TC_MAP8 is refreshed by the NC every time the magazine is

moved.

When the magazine configuration has been loaded, variable $TC_MAP8 is assigned the value

zero. The position value is the number of the magazine location that is located at the zero

position of the magazine. As a maximum, the magazine position can have the number of

magazine locations in the magazine. Larger or negative values are rejected.

$TC_MAP10

Magazine-specific tool search

The bit settings correspond precisely to the system variables $TC_MAMP2.

The default setting "0" always applies to buffer magazines, that is to say the search is made

forwards from the 1st magazine location.

Writing magazine location data

Points to be noted about writing magazine location data:

When writing to a $TC_MPP... parameter for the first time, all of the magazine locations defined

by magazine parameters are created with their default values (the memory for the locations is

therefore "used up"). I.e. the magazine must have been defined by this time ($TC_MAP...

parameter).

$TC_MPP1 (location type)

Only magazine locations of the type "Magazine location" ($TC_MPP1 = 1) may be defined at

magazines that are not of the type "internal" ($TC_MAP1 = 7 or = 9).

Location types:

•

1 = Magazine location

Only locations of type "1" can be defined on real magazines.

•

2 = Spindle / tool holder

•

3 = Gripper

•

4 = Loader

•

5 = Transfer location

The distinction gripper / loader / transfer location is intended for HMI applications. Here, NC

does not make a distinction, loader and transfer location are treated just like a gripper.

•

6 = Loading station

After the tool moves to this location, the tool stays there. It can only be removed by explicit

operation (unloading).

•

7 = Loading point

If a tool is moved from the magazine or buffer to this location, after the PLC acknowledgement

of this motion command, the tool is automatically removed from this location.

Function Manual, 10/2020, 6FC5397-1HP40-0BA1

NC programming

7.6 Magazine data

Please note when writing the location status and number of the tool in this location that the

following dependencies on $TC_MPP2 to $TC_MPP4 apply; these are checked during the write

operation:

• If the location already contains a tool, the location type to be written must be checked against

the tool location type.

• The status "not occupied" may only be written when none of the "assigned" states is set and

there is no tool at the location.

• The "Disabled" state can be set irrespective of the other states.

• If there is no tool contained then the state "free" is automatically active; i.e. the state "not

free" cannot be set by the NC program or PLC, HMI.

• "Occupied" states can only be set by the NCK within the scope of the adjacent location

consideration; i.e. these states are ignored during writing by the NC program or PLC, HMI.

• The state "Reserved for tool from buffer" is set when a tool is removed by the NC from the real

magazine during a tool change. This location is then not designated as "free" for tools other

than the tool removed.

• The states "reserved for tool from buffer" and "reserved for new tool to be loaded" of a

location are automatically reset when a tool is placed in this location.

• The states "reserved for tool from buffer" and "reserved for new tool to be loaded" of a real

magazine location are automatically reset when a tool from this location is placed at a

location in the loading/unloading magazine.

• The state "reserved for tool from buffer" is reset during an empty location search if the tool

for which the empty location is being sought is assigned a magazine location other than its

previous real magazine location. The newly found empty location is assigned the state

"Reserved for tool from buffer" and becomes the new owner of the tool being sought.

The magazine location state "Reserved for tool to be loaded" is always reset when the control

system is restarted. If "Consider adjacent location" is active, reservations of adjacent locations

are also considered.

Users only have to deal with these rules if they wish to define the magazine directly at the NC

program level. Data back-up is such that the rules are observed when data is imported to the NC.

$TC_MPP5 (location type index)

This data contains the spindle number for magazine locations of type "spindle" ($TC_MPP1) and

is thus made known to the tool management.

The value cannot be changed for location type = 1 ($TC_MPP1; i.e. for all locations of internal

magazines) if there is a tool at the location.

$TC_MPP6 (T No.)

• Tools can only be placed in magazine locations when both the tool and the magazine, plus

its magazine locations, have been defined.

The tool may occupy only one magazine location!

Procedure:

Tool management

Function Manual, 10/2020, 6FC5397-1HP40-0BA1

7.6 Magazine data

It first attempts to find the tool associated with the T No.

• If it is already defined, then an attempt is made - subject to appropriate check procedure - to

add it to the magazine location.

• If it is not yet defined, then an error has occurred.

Checks:

• The type of the tool to be placed must match the type of the location. If the type has not been

set explicitly at the time of writing (default = 9999 = "Not defined"), then the tool is not

placed.

• The state of the location must be "free" and must not be "disabled".

• If the value T No.=0 is programmed, then this means that the present tool will be removed

from the magazine location.

Notice: $TC_MPP6 = 0 also changes the state of the location: a tool can only be placed in a

magazine location if the location does not already contain a tool. The old tool might first have

to be removed with $TC_MPP6 = 0.

Note

Because of this dependency of the individual data, it is mandatory for the T number of the

tool to be written as the last data in a magazine configuration. If you do not adhere to this

sequence, default values might be set which may result in unwanted data.

If a tool is to be loaded into the magazine, then the location type determines the availability of

locations, i.e. $TC_TP7 and $TC_MPP2 must be defined.

If the location type of the tool is part of the location type hierarchy, then the location assignment

is carried out in accordance with this hierarchy.

Several such hierarchies can be set up in one TO-area unit, With a conventional hierarchy, a

location type may only be entered in one hierarchy.

Example

A chain magazine is to be split into 6 location types and the following hierarchy defined (the

magazine No. is "1", the numbers of the location types are selected at random).

Description

Magazine position

The current magazine position is required for tool change, loading and unloading. This position

refers to the magazine zero point established by the machine manufacturer. This is usually at the

change position.

The number of the location at the magazine zero point has to be given during initialization.

Otherwise, it is assumed that the non-existent location 0 is at the change position.

If the magazine is moved by a task, the current position is changed accordingly. The NC does not

know how many positions the magazine has moved but knows the targets of the relevant

commands. On the basis of the defined distance between and object (e.g. spindle 2) and the

change position, the NC is able to update the current position.

Comment:

The value of the distance and the current magazine position are also evaluated for box

magazines.

For empty location searches and tool searches, search strategies based on reference to the

current magazine position convert the position contained in system variable $TC_MAP8 to the

change position, loading point in each case at which the search is started. With search tasks, the

NC always specifies internally which change position, loading point is to be used as reference for

the search.

Assignment

By defining $TC_MDPx[n,m], a connection or assignment (distance relationship) is established

between the real magazine and the buffers or the loading points. The HMI can only display

assigned buffer locations and loading points. A tool transport within the scope of a t preparation

or a change can only be realized via an assigned buffer (exception: asynchronous transfers). The

tool search, for T preparation and change is also only made in those magazines assigned to a

spindle or tool holder.

The maximum number of these distance relationships can be defined with machine data

$MN_MM_NUM_LOCS_WITH_DISTANCE.

Tool management

Function Manual, 10/2020, 6FC5397-1HP40-0BA1

197

NC programming

7.6 Magazine data

Example: 1st TO unit, 1 magazine, 1x spindle, double gripper, 2x loading point. This is a total of

5 distance relationships (3x $TC_MDP2 to assign the real magazine to the 3 buffers, 2x

$TC_MDP1 to assign the real magazine to the two loading points).

Note

Command $TC_MDP2[n,m]=9999 can be used to dissolve a distance relationship.

Distance to change position $TC_MDPx[y,z]=value

The magazine zero point is usually the change position of the spindle. Therefore, the following

applies:

• If location 1 is located at zero position, the current magazine position = 1 ($TC_MAP8[1]).

Examples for programming the distance to the zero position:

$TC_MDP1[1,1] = 5

a tool that can be used was found among the tools that were searched.

If a search is made according to the strategy, bit 2=1 (sequence of use $TC_TP10) then the same

principle applies. The criterion is also "active tool" and instead of the duplo number, the number

Assumption:

• All tools can be used

• Basic setting of the search strategy is bit 0 = 1 - search for the active tool, if there is no active

tool, take the tool with the lowest duplo No.

• Spindle_1 is linked to both magazines, magazine_1 is the first in the distance table

Example_1:

Bit 6 = 0

Bit 7 = 0

T="Mill_15" M06

There is only one "Mill_15" tool, it was found in magazine_1 and was

loaded

T="Tool3"

M06

The last change was performed from magazine_1. Therefore, the

search is first made in magazine_1. There is no active "Tool3" there,

but there are two tools in this group that can be used. The tool with the

lowest duplo no. is selected. Magazine_2 is no longer considered.

Example_2:

Bit 6 = 0

Bit 7 = 1

T="Mill_20" M06

There is only one "Mill_20" tool, it was found in Magazine_2 and was

loaded

T="Tool3"

M06

The last change was performed from Magazine_2. As a result of bit 7

= 1, the tool search is however started in Magazine_1. But this setting

also means that the search strategy "active tool" has priority over a

magazine-specific approach. This means that: No active tool from the

group "Tool3" was found in Magazine_1, i.e. the search is continued

in the next magazine (corresponding to the sequence in the distance

table). An active "Tool3" is there - and this is selected.

Example_3:

Bit 6 = 1

Bit 7 = 1

T="Mill_20" M06

There is only one "Mill_20" tool, it was found in Magazine_2 and was

loaded

T="Tool3"

M06

The last change was performed from Magazine_2. As a result of bit

7 = 1, the tool search starts in Magazine_1. However, no tool of this

group is present there. As a result of bit 6 = 1 (considers the actual

magazine with priority), a search is now made for a "Tool3" that can

be used in Magazine_1 (for this search, this is also the actual mag-

azine); this tool is also found.

For software releases less than 2.5, the tool search is always made magazine for magazine,

starting in the magazine from which the last change was made.

With bit 7 there is an additional option to select the tool search.

Bit 7 = 1

The search always starts in the 1st magazine of the distance table. If the search for the active tool

is set using either bit 0 or bit 2, a search is made for the active tool across all of the magazines

linked with the spindle. A search is only made for a replacement tool if no active tool was found

in all of these magazines.

Note

The tool sequence in a tool group is not defined (e.g. ascending duplo number). This means, if

the default strategy is used for the search (MAMP2=0), any tool that is capable of being used is

found.

This assignment is important when searching for tools. The search is always made, viewed from

means that a tool, which is located in the buffer, can only be found if there is an assignment to

the spindle via parameter $TC_MLSR.

gripper is linked to the spindle via $TC_MLSR[2,1]=0 and $TC_MLSR[3,1]=0. The correct value

for the MD is "2".

The sequence when programming is decisive for the sequence when automatically returning

tools.

Note

The content value of the system variable is not evaluated. The assignment is defined via indices

x and y. In order to check via the part program whether a certain assignment exists, a read

operation has to return the value zero.

Note

No more than 16 magazines or buffer locations can be assigned to one spindle.

Overview

A multitool is a combination of several tools to form a unit. The following parameters allow a

multitool to be described so that it fits into the systemology of the tool magazine function.

All of the parameters in the following table have no physical units. The default access right is

"key-operated switch position 0" - for access operations from the NC program as well as for

access operations from the OPI. Access rights can be restricted using the REDEF command.

$TC_MTPN - number of MT locations

The multitool does not have a duplo number like the tool. The parameter $TC_MTPN contains the

number of locations, which the multitool offers to accept tools. In addition, by programming

$TC_MTPN[mtNo] = 0 the multitool is deleted. After MT locations have been generated, the

parameter can no longer be changed.

A multitool is similar to a chain magazine with regard to its locations, i.e. if there are tool search

strategies or empty location search strategies with results that depend on the type of magazine,

the property can be like that of a chain magazine.

$TC_MTP2 - MT name

Multitools can be assigned names so that a multitool can be uniquely defined by its name or by

its number. The rules that apply when assigning names are the same as those that apply to tool

names. Multitool names must be different from tool names and magazine names within a TO

unit.

$TC_MTTP3 $TC_MTP6 - MT size

The size data of a multitool is essentially the same as the size data of a tool - and is used to find

an optimally suitable magazine location for the multitool when loading into the magazine

(empty location search) when consider adjacent location is active.

The rules for changing the multitool size are the same as the rules for changing the tool size, i.e.

the MT size of a multitool can be changed so long as the MT is not assigned to an owner location.

$TC_MTP7

The magazine location type of the multitool is essentially the same as the magazine location

type of a simple tool and is required for the empty location search, empty location check (loading

operations into the magazine, tool change). The permitted values and rules to change data

correspond to those that apply for the corresponding data in the tool. The value cannot be

changed if the multitool is loaded into the magazine.

For multitools that are contained in the loading magazines or buffer magazines and still do not

have an owner location (i. e. that are logically valid as unloaded - $A_MYMN=0, $A_MYMLN=0),

the magazine location type can be changed. The magazine location type of a multitool can be

changed, as long as the multitool is still not assigned to an owner location.

If the state is set, it is permitted to select another tool from the MT, if this selection

regarding the same toolholder is realized just like the selection, that had set the

state of the MT. In this case, there is no competing tool selection, but instead a

replacing one. If the state is set, then a tool in this MT also has this state set. The

state is reset again together with that of the tool. Bit 21 from $TC_TOOL_MAN-

Manual tool

The multitool is used as manual tool. The state is set and reset again for the MT as

part of the tool selection. The tool to be selected and its MT change state synchro-

nously. The tools not involved with the tool selection do not experience a state

change.

MT is locked if a tool in the MT is

If a tool contained in the MT has made the state transition to "disabled", then the MT

locked

also assumes this state (bit 2). After a tool has made the state transition to "not

disabled", and then there is no longer any tool in the multitool that has the "disa-

bled" state, then the MT itself also loses the "disabled" state.

Loading/removing a disabled / enabled tool to the MT or from the MT can change

the MT state "disabled/enabled".

Example: Loading to a disabled tool corresponds to an MT state transition to "dis-

abled".

Note

Reserved or non-defined MT state bits cannot be written to. Writing to such a bit results in Alarm

17050 "illegal value".

Interdependencies between the tool and multitool states

Tools, which are loaded in the multitool, can influence the state of the multitool and for MT

transport operations, the MT can influence the tool status of the loaded tool.

Released

Users allocate tools and multitools a status independent of one another. (Enabled

tools can be loaded into a multitool that has not been enabled. Tools that have not

been enabled can be loaded into an enabled MT.)

Blocked

Changing this state is initiated from the tool as part of the tool monitoring and the

command RESETMON . Examples 1a, 1b, 2a, 2b at the end of this table show how

the state of loaded tools can influence that of the multitool.

User-specific changes to the MT state are not transferred to the loaded tools.

is being changed

The state is set and reset again for the MT as part of the tool selection. The tool to

be selected and its MT change the state synchronously. The tools not involved with

the tool selection do not experience a state change.

The state is always reset at POWER ON.

fixed-location-coded

Tools loaded in the MT are implicitly fixed-location-coded, i.e., the state has no

significance for the tool in the MT. For the MT itself, the state is defined; however,

this has no influence on the loaded tools. If the tool state changes, this has no

effect on the state of the multitool.

was in use

The state is automatically set as part of the tool change for the MT and the tool in

the MT involved in the change. Tools in the MT, not involved in the tool change, do

not change the state.

The user is responsible for the reset. If the last tool contained in the MT loses this

state, the MT also loses this state. If the user deletes the multitool state, then the

states of all of the tools contained in it are also deleted.

If the user sets this MT state, it has no effect on the loaded tools in the MT.

autom. return transport

At the tool change, the state is automatically set and reset for the MT only, however

not for the tools contained in the MT.

MT is to be unloaded

When unloading from the magazine, the MT and the its loaded tools lose this state.

If a tool that has this state set is removed from the MT, then the state in the tool that

When loaded to a magazine location, the MT and the tools loaded in it lose this

MT is locked

Notice

If tools are in the MT at the time of the state change, the following applies: When

the state is changed, the state of the loaded tools is checked and the MT state

"disabled" set or reset.

Notice

The loading/removing of a tool to the MT / from the MT causes the states of the tools

loaded in the MT to be checked loading/removing has been completed and the MT

state "disabled" is set accordingly. See examples 4a, 4b.

Example 1a:

Bit 2 = 0 and bit 16 = 1

The MT has three tools that are not disabled and have been enabled. The MT itself is also not

disabled and has been enabled. Bit 16 is set to 1.

If the "disabled" state of any tool in this MT is set (either manually or automatically), the

"disabled" state will also be set in the MT, although there are still two tools for which the

"disabled" state has not been set (i.e., these tools can still be used).

Example 1b:

Bit 2 = 1 and bit 16 = 1

The MT has three tools that are disabled and have been enabled. The MT itself is also disabled

and has been enabled. Bit 16 = 1 is set.

If the "disabled" state of two of the three tools is deleted in the MT, then the "disabled" state of

the multitool itself remains unchanged. If, for the last tool with the "disabled" state, the

"disabled" state is deleted (either manually or automatically), then the "disabled" state is also

deleted in the MT.

Example 2a:

Bit 2 = 0 and bit 16 = 0

The MT has three tools that are not disabled and can be used. The MT itself is also not disabled

and has been enabled. Bit 16 = 0 is set.

If the "disabled" state of two of the three tools is set in the MT (either manually or automatically),

then the status value of bits 2 in the MT remain unchanged. This means that the last "not

disabled" tool of the multitool can still be loaded. The MT is only set to the "disabled" state when

this last tool also enters the "disabled" state.

Example 2b:

Bit 2 = 1 and bit 16 = 0

The MT has three tools that are disabled and can be used. The MT itself is also disabled and has

been enabled. Bit 16 = 0 is set.

If the "disabled" state of a tool in the MT is deleted (either manually or automatically), then in

addition, the "disabled" state in the MT is also deleted, independent of the state of the other tools

in the MT.

Bit 16 = 0 is advantageous, for example, if the MT only contains identical tools. All tools can then

be used until their relevant monitoring limit has been reached.

Bit 16 = 1 is advantageous, for example, if an MT is to be loaded and the tools it contains are

different and have to perform various machining operations. If one of these tools is now disabled

due to the monitoring function, then another MT must be loaded, which contains a complete set

of tools that are ready for use for this particular machining operation.

A graphic representation of the "disabled" state coupling is again shown in the following two

diagrams:

$TC_MTP_POS - MT position

The position of the multitool is the MT location number of the location, which is in the machining

position, and which typically contains the machining (active) tool; see the next figure.

With the final acknowledgement (PLC status value = 1) of a tool change command for a tool in

the MT, the MT position is set to the value of the MT location number of the MT location, which

contains the tool that was loaded. The other PLC status values (e.g. status_105) do not change

the MT position value.

With the end acknowledgement (PLC status value = 1) of an MT positioning command (POSMT,

_N_POSMT), the MT position is set to the value of the programmed MT location number. The

other PLC status values are not permitted for the MT positioning command and are rejected with

Alarm 6405 "incorrect acknowledgement data".

With an asynchronous transfer control, the PLC can position the multitool.

If a command output to the PLC is not acknowledged with "end" (e.g. cancel, status_3), then the

MT position in the NC is not updated (even if the positioning has already been mechanically

carried out).

The MT position of a multitool, which is not located in a toolholder, has no further significance.

The exception is programming T="magazine location number", which is typically used for

revolvers.

Figure 7-11

The location on the machining position determines the MT position

Example 1:

An MT is moved to the tool holder with a tool motion command (e.g. MVTOOL). The parameters

are set according to the current MT position. With the final acknowledgement of the MT motion

command, the PLC can inform the NC whether and how the position of the multitool is to be

updated.

• The FC6 is parameterized with MultitoolLoc=0. NC does not perform a position

synchronization, the mechanical position can differ from the data position.

• The FC6 is parameterized with MultitoolLoc=1 (valid MT location number). This means that

the NC synchronizes the MT position with the acknowledged position.

If subsequently a tool change is programmed for a tool of this MT on the tool holder, a tool

change command is output to the PLC with which the MT positioning data is sent to the PLC. With

the final acknowledgement of the tool change, the MT position is updated to the value that

belongs to the tool that is to be loaded. The PLC must have performed the MT positioning before

the final acknowledgement is sent to the NC. The PLC must not change the MT position for the

tool selection, tool change commands specified by the NC in the acknowledgement data. The

attempt is rejected with alarm 6405 "Command has invalid PLC acknowledgement parameter".

Example 2:

An MT is moved to the tool holder with a tool motion command (e.g. MVTOOL). As in example

1, the MT positioning/synchronization depends on the PLC application.

If subsequently a RESET is executed, then - when RESET is configured with "Activate tool on the

master tool holder" - a tool change command is output to the PLC with which the data of the tool

to be activated and the MT positioning data is sent to the PLC. With RESET, the tool to be activated

is specified in the NC as the tool at the MT location displayed at the MT position output to the PLC.

This means that in this example, it depends on the PLC logic for the tool motion on the master

tool holder, which tool is activated at RESET. If a different tool is to be activated, this must be

specified in the application , for example by positioning the MT appropriately first with the NC

program command POSMT (or similar PI _N_POSMT by the HMI or PLC). It is also possible to set

the MT position in the NC directly to the desired value before the RESET (by programming

parameter $TC_MTP8 or by writing the position via the operator panel interface (by the HMI or

PLC), or the PLC positions the multitool with an asynchronous transfer).

$TC_MTP_KD - type of distance coding for the MT locations

The location distances (KindOfDistance) within the multitool can be defined in a variety of ways:

$TC_MTP_KD[y] = 1

The distance coding uses the MT location number. The location num-

ber is automatically allocated when creating the MT locations.

$TC_MTPPL, $TC_MTPPA cannot be written except with the value 0.0.

$TC_MTP_KD[y] = 2

The distance coding is via length specifications. $TC_MTPPL can be

written, $TC_MTPPA cannot be written, except $TC_MTPPA[...]=0.0.

$TC_MTP_KD[y] = 3

The distance coding is via angle specifications. $TC_MTPPA can be

written, $TC_MTPPL cannot be written, except $TC_MTPPL[...]=0.0.

The type of distance coding can only be changed as long as no MT locations have been created.

Otherwise Alarm 6438 "Inconsistent data modification is not permitted" is generated.

Example:

If, for distance coding, the location number has been defined ($TC_MTP_KD[ y ] = 1), then

writing $TC_MTPPL, $TC_MTPPA with values other than 0.0 results in alarm 6464 "Command

cannot be programmed for the current multitool distance coding".

Example:

The multitool is defined. Although the number of MT locations has been defined, they have still

not been created.

$TC_MTP_KD[200] = 1

;subsequently writing to $TC_MTPPL or $TC_MTPPA results in

;Alarm "Command cannot be programmed for the defined multi-

tool distance coding"

$TC_MTP_KD[300] = 2

;subsequently writing to $TC_MTPPL is permitted.

;subsequently writing to $TC_MTPPA results in Alarm

;"Command cannot be programmed for the defined

;multitool distance coding"

The MT locations are now created, e.g. by writing to the system of parameters:

$TC_MTPPL[300, 1] = 30.0

; all MT locations are implicitly created using the command

Then an attempt is made to change the distance type (that was previously defined using

$TC_MTP_KD[300] = 2):

$TC_MTPPL[300, 1] = 3

;After the MT locations have been created, the type of

Positioning a multitool

It is only possible to position a multitool, if

a) It is located on a tool holder

b) No offset is active. This means that none of the tools in this multitool may be active.

Positioning can be performed via the language command POSMT or the similar PI service

(POSMT). Positioning from the PLC via an asynchronous transfer is also possible.

$TC_MTPP2 - MT location type

The location type of a tool must match the location type of the MT location. It is checked when

the multitool is loaded by writing parameter $TC_MTPP6.

The location type may only be changed when the new value is compatible with the value of the

location type of a loaded tool.

The default value is selected (each tool fits the MT location) in such a way that, when the

"Location type check" function is not required in the specific application for the tool loading

operation, the parameter does not have to be considered, and therefore the default setting is

already suitable.

$TC_MTPP4 - MT location state

The following location states have been defined (bit numbers and definition based on the state

of the magazine location; $TC_MPP4):

0 Disabled

1 Free to accept a tool

$TC_MTPP6 - T number of the loaded tool

The locations of the multitools can be loaded with tools. The loading can only be defined with

the aid of parameter $TC_MTPP6. In particular, loading involving the PLC has not been defined.

(The OPI PI service _N_TMMVTL and the NC language command MVTOOL are exclusively for the

loading/unloading of tools and multitools to and from magazines.) With $TC_MTPP6[MT no.,

loc. no.] = T number, loading is performed. With $TC_MTPP6[MT no., loc. no.] = 0, a tool is

removed from the multitool.

The multitool can contain tools with the same or different names. Each tool fits into each location

of a multitool with the default value of $TC_MTPP2. Generally, it is assumed that a multitool is

a mechanical entity whose correct loading is the sole responsibility of the user.

If $TC_MTP8, bit 16 = 1 has been set for the MT state, the following must be considered:

When loading a tool to an MT or removing a tool from an MT, the MT state "disabled"/"not

disabled" can change. The following applies:

• After loading, the states of the tools in the MT determine whether and how the state of the

multitool is changed automatically.

When removing a tool from an MT, the following applies:

• After removing the tool, the states of the remaining tools in the MT determine whether and

how the state of the MT is changed automatically.

7.7 Multitool data

Formally, a tool can be loaded to an MT or removed from an MT at any time. It is the responsibility

of the user to ensure compliance with the application. For example, the user must know what

it means to remove an MT loaded on a tool holder from the tool holder, or to remove and active

tool from an MT.

A tool can be assigned either to a magazine or to an MT, but not to both at the same time. Such

an attempt is rejected with alarm 17260 "Illegal magazine location definition".

When loading a tool to an MT, the magazine location type of the tool and the MT location are

checked for compatibility if the MT location type does not have the value "Every tool fits the

location" (this is the default value). A tool can only be loaded to an MT location when the state

of the MT location is "Free".

Note

Multitools do not have a "Consider adjacent location" function for oversized tools. This means

that the tool size is not evaluated when loading a tool to an MT location.

$TC_MTPPL, $TC_MTPPA - Location distance

The distance between the tools in the multitool is defined alternatively with one of these

parameters. Which parameter is to be defined for the specific multitool is determined via the MT

parameter $TC_MTP_KD. The change rules for the date are those that have also been defined for

the multitool sizes. System parameters are not required for the distance coding "MT location

number". When creating the locations for an MT, the locations are automatically assigned the

numbers 1, 2, ...

D numbers of replacement tools

Replacement tools can be defined and used when tool management is active. The machining

part program does not generally indicate whether any replacement tools are available. As a rule,

the machining program addresses tools with T="Identifier". (Programming T="location number"

is referred back to T="identifier" internally). The program otherwise only contains the actual

programming of the offset (the D number). Therefore, the D number for the tool and

replacement tool must be identical.

Example

Active tool and replacement tools for T="drill_5mm"

• T No. = 10 with D numbers 1, 2, 3 (active)

• T No. = 11 with D numbers 1, 2, 3 (replacement)

• T No. = 12 with D numbers 1, 2, 3 (replacement)

Active tool and replacement tools for T="drill_3mm"

• T No. = 20 with D numbers 1, 2, 3 (active)

• T No. = 21 with D numbers 1, 2, 3 (replacement)

• T No. = 22 with D numbers 1, 2, 3 (replacement)

CHKDNO - without parameters specified - detects a collision of D numbers 1, 2 and 3 for

"drill_5mm" with D numbers 1, 2 and 3 for "drill_3mm", but not between the D numbers of the

active and replacement tools.

The collisions are displayed as individual alarms, e.g.:

• "Channel 1 D number 1 defined for tool T no. 10 and 20"

• "Channel 1 D number 1 defined for tool T no. 10 and 21"

The state = FALSE is also returned in the event that the parameterization is invalid. (The T or D

number called is not defined in the channel.)

If the following applies: MAX_CUTTING_EDGE_NO ≤ MAX_CUTTING_EDGE_PER_TOOL ,

CHKDNO always returns the TRUE state, irrespective of the parameter settings.

SETPIECE - decrementing the workpiece counter

With the SETPIECE function, the user can update the count monitoring data of the tools

associated with the machining process. Each tool that has been loaded since the last activation

of SETPIECE is acquired. The function serves as a rule for programming at the end of the NC

part program to decrement the count from all the tools associated with count monitoring.

Note

The command is not active in the block search (with/without calculation). If the value for the

count = 0, the internal table for flagged tools/cutting edges is deleted.

Note

SETPIECE works through the table "blindly". This means that every cutting edge entered in the

table is recorded. It is irrelevant where the tool is located at the time of the SETPIECE

programming, whether it is stored in the magazine, remains on the spindle, or has been

unloaded.

If it is set that the tool remains active after a reset and there is a tool in the spindle at the start

of the program, this tool is selected internally and an entry is made in the Setpiece table.

GETSELT - Read the selected T number

The function GETSELT is available with TMMO and TMMG.

The GETSELT function returns the T number of the selected tool with regard to the individual

tool holders or spindles from the NC program viewpoint and is used to access the offset data of

the selected tool during T programming and cutting edge selection.

During preprocessing or while the NC program is running, the selected T number is not available

until after the next cutting edge selection. The task of the function GETSELT is to establish

synchronization with the main run earlier.

NOTICE

Alarm delay

If an alarm delay is active ($MC_TOOL_CHANGE_ERROR_MODE, bit 0 = 1) and an alarm occurs

during the tool preparation, which is to be delayed until after M06 and programmed before the

programming of M06 GETSELT, the T number found by GETSELT has the value = -1.

Block search: Returns the tool selected before block

search or test mode

If "ssl" is set (="S" for "searchrun"), during the block search or test mode, the GETSELT NC

command returns the tool number of the selected tool on the specified tool holder before the

block search or before the test mode. At the end of the block search or test mode, the GETSELT

NC command returns the value irrespective of ssl after the first T programming for the specified

tool holder.

After program end / abort, the T numbers of all the tool holders that were returned with GETSELT

are set to the value = 0. For the master tool holder, the value is then set to the corresponding

setting in $MC_RESET_MODE_MASK, or after a program restart to the corresponding setting in

$MC_START_MODE_MASK.

If required, the function makes an implicit preprocessing stop if the main run has not received

the tool preparation command.

OPI variable

The values supplied by the "GETSELT" function are available in the OPI variable "toolHolderData"

of the C/S block.

Parameter no. 2 returns the value of GETSELT(tNo, Th).

Parameter no. 4 returns the value of GETSELT(tNo, Th, "S").

The OPI variable is available in all versions of the tool management.

Data type:

INT

= 0

There is no loaded T number or the tool has been deleted in the

meantime (occurs only with ssl="S").

th= 0,1, ..., ≤ 20

Number of spindle or of the tool holder (optional). If th is not specified, GETEXET refers to the

current master spindle.

Data type:

INT

= 0:

If ssl="" or is not set, the command refers to the currently active main

spindle / tool holder.

If ssl="S", the command refers to the tool holder that determined the

D offset before the block search.

ssl

Block search (optional)

Data type

CHAR

= "":

Function as previously, i.e. the current state after the NC program

= "S":

Block search function: Returns the tool loaded before the block

search or test mode.

If "ssl" is set (="S" for "searchrun"), during the block search or test mode, the GETEXET NC

command returns the T number of the loaded tool on the specified tool holder before the block

search or before the test mode. At the end of the block search or test mode, the GETEXET NC

command returns the value independent of ssl after the first programming of a tool change for

the specified tool holder.

If required, the function makes an implicit preprocessing stop if the main run has not received

the tool change command.

After the program end / abort, the "getexet" T numbers of all tool holders are set to the value =

0. For the master tool holder, the value is then set to the corresponding setting in

Tool management

7.9 NC language commands

$MC_RESET_MODE_MASK, or after a program restart to the corresponding setting in

$MC_START_MODE_MASK.

Note

If the tool change is only programmed with T ($MC_TOOL_CHANGE_MODE), GETSELT and

GETEXET return the same T number.

If the tool change is programmed with T (selection) and M06 (change), the two commands have

different contents.

OPI variable

The values supplied by the "GETEXET" function are available in the OPI variable "toolHolderData"

of the C/S block.

Parameter no. 3 returns the value of GETEXET(tNo, Th).

Parameter no. 5 returns the value of GETEXET(tNo, Th, "S").

The OPI variable is available in all versions of the tool management.

Example (1)

Three tools are defined with Tno. = 5 / Name = "Tool5" , Tno. = 7 / Name = "Tool7" and Tno. = 9 /

Name = "Tool9".

The tool change is programmed with T + M6.

Two tool holders have been defined. Tool holder 2 is the master tool holder.

At the start, there is neither a tool on the tool holder nor a tool active or programmed:

Use of $P_TOOLNO - GETEXET

With active tool management, GETEXET should generally be used.

If the following specification are complied with, $P_TOOLNO can also be used:

After programming D, $P_TOOLNO always returns the correct value of the active T number.

tool change was performed as this was master tool holder.

In the above case, the variable $P_MTHSDC has the value 2, because on this tool holder the last

$P_TH_OF_D = 2

In a ProgEvent program, after a block search, the situation is to be established with regard to

tools and tool offset that would have existed without a block search.

After a block search on a block between N100 and N130, it is determined how the currently

active "D5" from block N30 is established. For this purpose, it must be recognized that "D5"

comes from the tool on tool holder 1. The last tool change on a main tool holder was performed

on block N20 on tool holder 1. This information is provided by system variable $P_TH_OF_D.

The variable $P_TH_OF_D specifies on which tool holder the tool is located that determines the

currently active D offset.

The variable $P_MTHSDC specifies on which tool holder the tool is located that determines the

offset at the next D programming.

$P_TH_OF_D = 0 means that currently no tool holder is defined to which the current tool offset

"D" refers. The active tool is then also T=0 and the active D no. =0.

GETACTT - Read the active internal T number

Function GETACTT returns the T number of the tool with status "active" and "was in use" via

parameter "TNo" from a tool group "name" (a tool becomes "active" immediately before it is

loaded into the tool holder)

Note

GETACCT cannot detect a tool that is positioned in the spindle for its first use.

The tool sequence in a group is not defined. GETACCT will read any random tool in the group

where the status bits "active" and "was in use" are set.
