Various NC/PLC interface signals and functions

12.2 Functions

Value range

Addressing a motor or drive data set n, with n = 1, 2, 3, ..., is realized based on its index i, with

i = n - 1 = 0, 1, 2, ...

• Motor data sets: MDS[ 0, 1, 2, ... 15 ]

• Drive data sets: DDS[ 0, 1, 2, ... 31 ]

Formatting interfaces

Formatting the request interface, i.e. which bits are used to address the motor data sets (MDS)

- and which are used to address the drive data sets (DDS) is set via the formatting interface

(Page 688).

Motor and drive data sets in the drive

The number of motor data sets (MDS) and drive data sets (DDS) in the drive can be determined

using the following drive parameters:

• p0130 (number of motor data sets)

• p0180 (number drive data sets)

Motor data set (MDS) for main spindle drives

For main spindle drives, the following association applies:

• MDS[ 0 ] → star operation

• MDS[ 1 ] → delta operation

12.2.5.4

Display interface

The active motor data set (MDS) and drive data set (DDS) are displayed via the interface:

DB31, ... DBX93.0 - .4 == <MDS / DDS index>

Value range and formatting are identical to the request interface (Page 688).

12.2.5.5

Example

Two motor data sets (MDS) and two drive data sets (DDS) are available in the drive for each motor

data set. This corresponds to "No.": 9 of the possible data set combinations displayed in

the Figure 12-2 Principle of the motor/drive data set switchover (Page 691).

Format

Bit positions for drive data set switchover (DDS):

• DB31, ... DBX130.0 == 1

Examples

12.3.1

Parameter set changeover

A parameter set changeover is performed to change the position control gain (K_Vfactor) from K_V

= 4.0 to K_V = 0.5 for machine axis X1.

Preconditions

The parameter set changeover must be enabled by the machine data:

MD35590 $MA_PARAMSET_CHANGE_ENABLE [AX1] = 1 or 2 (parameter set change possible)

The 1st parameter set for machine axis X1 is set, in accordance with machine data with index "0"

Switchover

In order to switch over the position-control gain, the PLC user program selects the 4th parameter

set for machine axis X1.

• Request by PLC user program:

DB31, … DBX9.0 - DBX9.2 = 3 (parameter set servo)

- A request to change over to the 4th parameter set is sent for machine axis AX1.

- The parameter set is changed over once a delay has elapsed.

- Parameter set 4 is now active, in accordance with machine data with index "3"

• Feedback by NC:

DB31, … DBX69.0 - DBX69.2 = 3 (parameter set servo)

- The NC confirms/acknowledges the parameter-set changeover.

Brief description

13.1.1

Function

Auxiliary functions permit activation of the system functions of the NC and PLC user functions.

Auxiliary functions can be programmed in:

• Part programs

• Synchronized actions

• User cycles

For detailed information on the use of auxiliary function outputs in synchronized actions, see:

Further information

Function Manual Synchronized Actions

Userdefined auxiliary functions

User-defined auxiliary functions are either extended predefined auxiliary functions or user-

specific auxiliary functions.

Extension of predefined auxiliary functions

Extension of predefined auxiliary functions refers to the "address extensions" parameter. The

address extension defines the number of the spindle to which the auxiliary function applies. The

spindle function M3 (spindle right) is predefined for the master spindle of a channel. If a

13.1.2

Definition of an auxiliary function

An auxiliary function is defined by the following parameters:

• Type, address extension and value

The three parameters are output to the NC/PLC interface.

• Output behavior

The auxiliary function-specific output behavior defines for how long an auxiliary function is

output to the NC/PLC interface and when it is output relative to the traversing motion

programmed in the same part program block.

• Group assignment

An auxiliary function can be assigned to a particular auxiliary function group. The output

behavior can be defined separately for each auxiliary function group. This becomes active if

no auxiliary function-specific output behavior has been defined. Group membership also

affects output of an auxiliary function after block search.

If tool management is active, neither a T change signal nor a T word is output at the channel-

specific NC/PLC interface.

The type for the values can be selected by the user via MD22110 $MC_AUX-

Because of the limited display options on the operator panel screens, the REAL type values

displayed are restricted to:

-999 999 999.9999 to 999 999 999.9999

The NC calculates internally but with complete accuracy.

The REAL values are rounded and output to the PLC when setting the machine data:

MD22110 $MC_AUXFU_H_TYPE_INT = 1 (type of H-auxiliary functions is an integer)

The PLC user program must interpret the value transferred according to the machine data

setting.

13.2 Predefined auxiliary functions

If the tool management is active, the meaning of the address extension can be parameter-

ized. Address extension = 0 means the value must be replaced by that of the master spindle

number, i.e. it is equivalent to not programming the address extension.

Auxiliary functions M19 "Position spindle" collected during a block search are not output to

the PLC.

M6: Range of values of the address extension:

- without tool management: 0 ... 99

- with tool management: 0 ... maximum spindle number

0: To be replaced by the value of the master spindle number or master tool holder

If tool management is active, the auxiliary function M6 "Tool change" can only be program-

med once in a part program block, irrespective the address extensions that are programmed.

Maximum number of auxiliary functions per part program block.

13.2

Predefined auxiliary functions

Function

Every pre-defined auxiliary function is assigned to a system function and cannot be changed. If a

pre-defined auxiliary function is programmed in a part program/cycle, then this is output to the

PLC via the NC/PLC interface and the corresponding system function is executed in the NC.

Definition of a predefined auxiliary function

The parameters of the predefined auxiliary function are stored in machine data and can be

changed in some cases. All machine data, which are assigned to an auxiliary function, have the

same index <n>.

Auxiliary function outputs to PLC

13.2 Predefined auxiliary functions

Significance of the bits

Bit

Meaning

Acknowledgement "normal" after an OB1 cycle

An auxiliary function with normal acknowledgment is output to the NC/PLC interface at the beginning of the OB1 cycle.

The auxiliary function-specific change signal indicates to the PLC user program that the auxiliary function is valid.

The auxiliary function is acknowledged as soon as organization block OB1 has run once. This corresponds to a complete

PLC user cycle.

The auxiliary function with normal acknowledgment is output in synchronism with the part program block in which it

is programmed. If execution of the parts program block, e.g. path and/or positioning axis movements, is completed

before acknowledgment of the auxiliary function, the block change is delayed until after acknowledgment by the PLC.

In continuous-path mode, a constant path velocity can be maintained in conjunction with an auxiliary function with

normal acknowledgment, if the auxiliary function is output by the PLC during the traversing motion and before reaching

the end of the block.

Acknowledgement "quick" with OB40

An auxiliary function with quick acknowledgment is output to the NC/PLC interface before the next OB1 cycle. The

auxiliary function-specific change signal indicates to the PLC user program that the auxiliary function is valid.

The auxiliary function is acknowledged immediately by the PLC basic program in the next OB40 cycle. Acknowledgment

of the auxiliary function is not confirmation that the corresponding PLC user function has been executed. The auxiliary

function is still executed in the OB1 cycle. Next output of the auxiliary functions to the PLC is therefore not possible until

after this OB1 cycle has run completely. This is noticeable in continuous-path mode (drop in path velocity) especially if

auxiliary functions with quick acknowledgment are output in several consecutive part program blocks.

With auxiliary functions with quick acknowledgment, it cannot be guaranteed that the PLC user program will respond

in synchronism with the block.

Note

Parameterization of the output behavior of auxiliary functions as "quick auxiliary functions" is only possible in conjunc-

tion with user-defined auxiliary functions.

No predefined auxiliary function

A predefined auxiliary function is treated like a user-defined auxiliary function with this setting. The auxiliary function

then no longer triggers the corresponding system function but is only output to the PLC.

Example:

Reconfiguration of the "Position spindle" auxiliary function (index 9) to a user-defined auxiliary function with normal

acknowledgment and output prior to the traversing motion.

MD22080 $MC_AUXFU_PREDEF_SPEC [ 9 ] = 'H25' (100101B)

No output to the PLC

The auxiliary function is not output to the PLC.

Spindle response after acknowledgement by the PLC

The associated system function is only executed after acknowledgment by the PLC.

Output prior to motion

The auxiliary function is output to the PLC before the traversing motions programmed in the part program block (path

and/or block-related positioning axis movements).

Output during motion

The auxiliary function is output to the PLC during the traversing motions programmed in the part program block (path

and/or block-related positioning axis movements).

Output at block end

The auxiliary function is output to the PLC after the traversing motions programmed in the part program block have been

completed (path and/or block-related positioning axis movements).

Not output after block search, types 1, 2, 4

Block search, types 1, 2, 4: The auxiliary function collected during the block search is not output.

For a block search with program test, the auxiliary function is collected group-specific in the following system variables:

• $AC_AUXFU_M_VALUE[<n>]

• $AC_AUXFU_M_EXT[<n>]

• $AC_AUXFU_M_STATE[<n>]

No output during block search with program test (type 5, SERUPRO)

For block search with program test, the auxiliary function is not output to the PLC.

Cross-channel auxiliary function (SERUPRO)

For block search with program test (SERUPRO), the help function is collected on a cross-channel basis in the global list

of the auxiliary functions.

Note

For each auxiliary function group, only the last auxiliary function of the group is always collected.

Output performed via synchronized action (read only)

The bit is set if the auxiliary function was output to the PLC via a synchronized action.

Implicit auxiliary function (read-only)

The bit is set if the auxiliary function was implicitly output to the PLC.

Active M01 (read only)

The bit is set if the auxiliary function, for active M01, was output to the PLC.

No output during positioning test run

During the run-in test, the auxiliary function is not output to the PLC.

Parameterization

13.2.3.1

Group assignment

The handling of the auxiliary functions for a block search is defined using the group assignment

of an auxiliary function. The 168 auxiliary function groups available are subdivided into

predefined and user-definable groups:

Predefined groups:

1 ... 4

10 ... 12

72 ... 168

User-defined groups:

5 ... 9

13 ... 71

13.2 Predefined auxiliary functions

Each predefined auxiliary function is assigned, as standard, to an auxiliary function group. For

most pre-defined auxiliary functions, this assignment can be changed using the following

machine data:

MD22040 $MC_AUXFU_PREDEF_GROUP[<n>] (group assignment of predefined auxiliary

functions)

If an auxiliary function is not assigned to any group, then a value of "0" should be entered into

the machine data.

For the pre-defined auxiliary functions with the following indices <n>, the group assignment

cannot be changed: 0, 1, 2, 3, 4, 22, 23, 24

Note

1. Auxiliary function group and block search

Auxiliary functions of the 1st auxiliary function group are, for a block search, only collected, but

not output.

13.2.3.2

Type, address extension and value

An auxiliary function is programmed via the type, address extension and value parameters (see

Section "Programming an auxiliary function (Page 732)").

Type

The identifier of an auxiliary function is defined via the "type," e.g.:

"M"

For additional function

"S"

For spindle function

"F"

For feed

The setting is made via the following machine data:

MD22050 $MC_AUXFU_PREDEF_TYPE[<n>] (type of predefined auxiliary functions)

Note

The "type" cannot be changed for predefined auxiliary functions.

Address extension

The "address extension" of an auxiliary function is for addressing different components of the

same type. In the case of predefined auxiliary functions, the value of the "address extension" is

the spindle number to which the auxiliary function applies.

The setting is made via the following machine data:

MD22060 $MC_AUXFU_PREDEF_EXTENSION[<n>] (address extension for predefined auxiliary

functions)

Grouping together auxiliary functions

719

Auxiliary function outputs to PLC

13.2 Predefined auxiliary functions

To assign an auxiliary function for all spindles of a channel to the same auxiliary function group,

the value "-1" is entered for the "address extension" parameter.

Example:

The auxiliary function M3 (machine data index = 6) is assigned to the second auxiliary function

group for all the channel's spindles.

MD22040 $MC_AUXFU_PREDEF_GROUP[ 6 ]

= 2

MD22050 $MC_AUXFU_PREDEF_TYPE[ 6 ]

= "M"

MD22060 $MC_AUXFU_PREDEF_EXTENSION[ 6 ]

= -1

MD22070 $MC_AUXFU_PREDEF_VALUE[ 6 ]

= 3

Value

The parameters "value" and "type" define the meaning of an auxiliary function, i.e. the system

function that is activated on the basis of this auxiliary function.

The "value" of an auxiliary function is defined in the machine data:

MD22070 $MC_AUXFU_PREDEF_VALUE[<n>] (value of predefined auxiliary functions)

Note

The "value" cannot be changed for a predefined auxiliary function. For some predefined auxiliary

functions, the "value" can be reconfigured via additional machine data (see Section "Associated

auxiliary functions (Page 728)").

13.2.3.3

Output behavior

Parameter "Output behavior" defines when the predefined auxiliary function is output to the NC/

PLC interface and when it is acknowledged by the PLC.

The setting is done via the following machine data:

MD22080 $MC_AUXFU_PREDEF_SPEC[<n>] (output behavior of predefined auxiliary functions)

Output behavior relative to motion

Output prior to motion

• The traversing motions (path and/or block-related positioning axis movements) of the

previous part program block end with an exact stop.

• The auxiliary functions are output at the beginning of the current parts program block.

• The traversing motion of the actual part program block (path and/or positioning axis motion)

is only started after acknowledgment of the auxiliary functions by the PLC:

- Output duration one OB1 cycle (normal acknowledgment): after one OB1 cycle

- Output duration one OB40 cycle (quick acknowledgment): after one OB40 cycle

Basic functions

720

Function Manual, 10/2020, 6FC5397-2GP40-0BA1

Auxiliary function outputs to PLC

13.2 Predefined auxiliary functions

Output during motion

• The auxiliary functions are output at the beginning of the traversing motions (path and/or

positioning axis movements).

• The path velocity of the current parts program block is reduced so that the time to the end

of the block is greater than the time to acknowledgment of the auxiliary functions by the PLC.

- Output duration one OB1 cycle (normal acknowledgment): one OB1 cycle

- Output duration one OB40 cycle (quick acknowledgment): one OB40 cycle

Output after motion

• The traversing motions (path and/or block-related positioning axis movements) of the

current part program block end with an exact stop.

• The auxiliary functions are output after completion of the traversing motions.

• The block change is performed after acknowledgment of the auxiliary functions by the PLC:

- Output duration one OB1 cycle (normal acknowledgment): after one OB1 cycle

- Output duration one OB40 cycle (quick acknowledgment): after one OB40 cycle

Examples of different output behavior

The following figures illustrate the differing behavior regarding:

• Output and acknowledgment of the auxiliary function

• Spindle response (speed change)

• Traverse movement (velocity change)

The binary values specified in the diagrams under "Output behavior" refer to the parameterized

output behavior (MD22080).

Userdefined auxiliary functions

There are two uses for user-defined auxiliary functions:

• Extension of predefined auxiliary functions

• User-specific auxiliary functions

Extension of predefined auxiliary functions

Because there is only one set of machine data for the predefined auxiliary functions, they can

only ever be used to address one spindle of the channel. To address further spindles, user-

defined auxiliary functions must be parameterized to supplement the predefined auxiliary

functions.

Extension of predefined auxiliary functions refers to the "address extensions" parameter. The

number of the spindle that the auxiliary function refers to is entered in the "address extension"

parameter.

Address extension = 1 is the default value used in the auxiliary functions predefined in the machine data

Example:

Extension of the predefined auxiliary function for the system function "spindle right" for the

second and third spindle of the channel.

Auxiliary function "spindle right" for the second spindle of the channel:

MD22010 $MC_AUXFU_ASSIGN_TYPE[ n ]

= "M"

MD22020 $MC_AUXFU_ASSIGN_EXTENSION[ n ]

= 2

MD22030 $MC_AUXFU_ ASSIGN_VALUE[ n ]

= 3

Auxiliary function "spindle right" for the third spindle of the channel:

MD22010 $MC_AUXFU_ ASSIGN_TYPE[ m ]

= "M"

MD22020 $MC_AUXFU_ASSIGN_EXTENSION[ m ]

= 3

MD22030 $MC_AUXFU_ ASSIGN_VALUE[ m ]

= 3

User-specific auxiliary functions

User-specific auxiliary functions have the following characteristics:

• User-specific auxiliary functions only activate user functions.

• No system functions can be activated by user-specific auxiliary functions.

• A user-specific auxiliary function is output to the PLC according to the parameterized output

behavior.

• The functionality of a user-specific auxiliary function is implemented by the machine

manufacturer/user in the PLC user program.

13.3 Userdefined auxiliary functions

13.3.1

Parameterization

13.3.1.1

Maximum number of user-defined auxiliary functions

The maximum number of user-defined auxiliary function per channel can be parameterized via

the machine data:

MD11100 $MN_AUXFU_MAXNUM_GROUP_ASSIGN (maximum number of user-defined

auxiliary functions)

13.3.1.2

Group assignment

The handling of the auxiliary functions for a block search is defined using the group assignment

of an auxiliary function. The 168 auxiliary function groups available are subdivided into

predefined and user-definable groups:

Predefined groups:

1 ... 4

10 ... 12

72 ... 168

User-defined groups:

5 ... 9

13 ... 71

Every user-defined auxiliary function is assigned as standard to the 1st auxiliary function group.

The assignment can be changed using the following machine data:

MD22000 $MC_AUXFU_ASSIGN_GROUP[<n>] (group assignment of user-defined auxiliary

functions)

If an auxiliary function is not assigned to any group, then a value of "0" should be entered into

the machine data.

Note

1. Auxiliary function group and block search

Auxiliary functions of the 1st auxiliary function group are, for a block search, only collected, but

not output.

13.3.1.3

Type, address extension and value

An auxiliary function is programmed via the type, address extension and value parameters (see

Section "Programming an auxiliary function (Page 732)").

Type

The name of an auxiliary function is defined via the "type".

13.3 Userdefined auxiliary functions

The identifiers for user-defined auxiliary functions are:

Type

Meaning

"H"

Auxiliary function

User-specific auxiliary functions

"M"

Special function

Extension of predefined auxiliary func-

tions

"S"

Spindle function

"T"

Tool number

The setting is made via the following machine data:

MD22010 $MC_AUXFU_ASSIGN_TYPE[<n>] (type of user-defined auxiliary functions)

Address extension

MD22020 $MC_AUXFU_ASSIGN_EXTENSION[<n>] (address extension user-defined auxiliary

functions)

The functionality of the address extension is not defined in user-specific auxiliary functions. It is

generally used to distinguish between auxiliary functions with the same "value".

Grouping together auxiliary functions

If all the auxiliary functions of the same type and value are assigned to the same auxiliary

function group, a value of "-1" must be entered for the "address extension" parameter.

Example:

All user-specific auxiliary functions with the value "= 8" are assigned to the tenth auxiliary

function group.

MD22000 $MC_AUXFU_ASSIGN_GROUP [ 1 ]

= 10

MD22010 $MC_AUXFU_ ASSIGN_TYPE [ 1 ]

= "H"

MD22020 $MC_AUXFU_ ASSIGN_EXTENSION [ 1 ]

= -1

MD22030 $MC_AUXFU_ ASSIGN_VALUE [ 1 ]

= 8

Value

MD22030 $MC_AUXFU_ASSIGN_VALUE[<n>] (value of user-defined auxiliary functions)

The functionality of the "value" parameter is not defined in user-specific auxiliary functions. The

value is generally used to activate the corresponding PLC user function.

Grouping together auxiliary functions

If all the auxiliary functions of the same type and address extension are assigned to the same

auxiliary function group, a value of "-1" must be entered for the "value" parameter.

Example:

All user-specific auxiliary functions with the address extension "= 2" are assigned to the eleventh

auxiliary function group.

Output behavior

The "output behavior" of user-defined auxiliary functions can be parameterized via the machine

data:

MD22035 $MC_AUXFU_ASSIGN_SPEC[<n>] (output behavior of user-defined auxiliary

functions)

For a description of the individual output parameters, see the "Output behavior (Page 720)"

section of the predefined auxiliary functions. The information given there can be applied

analogously to the output behavior of user-defined auxiliary functions.

13.4

Associated auxiliary functions

Function

Associated help functions are user-defined help functions with the same properties as the

corresponding predefined help functions. User-defined auxiliary functions can be associated for

the following predefined auxiliary functions:

• M0 (programmed stop)

• M1 (optional stop)

G group

An associated help function is assigned to the G group of the corresponding predefined help

function.

Parameterization

Association of a user-defined auxiliary function with one of the predefined auxiliary functions

mentioned is set in the machine data:

• MD22254 $MC_AUXFU_ASSOC_M0_VALUE (associated M function for "Programmed stop")

• MD22256 $MC_AUXFU_ASSOC_M1_VALUE (associated M function for "Optional stop")

Selection

Selection of "Associated help function" (M-1) is made via the SINUMERIK Operate user interface

in the operating area "Automatic" > "Program control" by setting the HMI/PLC interface signal

DB21, ... DBX24.4.

Depending on the value of the FB1 parameter MMCToIf, the interface signal is transmitted from

the basic PLC program to the NC/PLC interface signal DB21, ... DBX30.5:

• "TRUE": Transmission

• "FALSE": No transmission

By default, the value of the parameter is "TRUE".

Note

Selection option via user interface SINUMERIK Operate

The selection of an associated help function is only displayed in the "Automatic" > "Program

control" operating area if it is parameterized in the machine data.

Application

Associated auxiliary functions can be used in:

• Main program

• Subprogram

• Cycle

Note

Associated auxiliary functions may not be used in synchronized actions.

NC/PLC interface signals

In the case of an associated user-defined auxiliary function, the same signals are output to the

NC/PLC interface as for the corresponding predefined auxiliary function. To distinguish which

auxiliary function has actually been programmed, the value of the user-defined auxiliary

function ("value" parameter) is output as the value of the auxiliary function. This means it is

possible to distinguish between predefined and user-defined auxiliary functions in the PLC user

program.

NC/PLC interface signals for associated help functions:

• DB21, ... DBX24.4 (associated help function selected)

• DB21, ... DBX30.5 (activate associated help function)

• DB21, ... DBX318.5 (associated help function active)

Boundary conditions

Please note the following boundary conditions:

• A user-defined auxiliary function may not be associated a multiple number of times.

• It is not permissible to associate predefined auxiliary functions (e.g. M3, M4, M5 etc.).

13.5 Type-specific output behavior

Examples

1. Associating the user-defined auxiliary function M111 for M0:

MD22254 $MC_AUXFU_ASSOC_M0_VALUE = 111

The user-defined auxiliary function M111 therefore has the same functionality as M0.

2. Associating the user-defined auxiliary function M222 for M1:

MD22256 $MC_AUXFU_ASSOC_M1_VALUE = 222

The user-defined auxiliary function M222 therefore has the same functionality as M1.

13.5

Type-specific output behavior

Function

The output behavior of auxiliary functions relative to a traversing motions programmed in the

parts program block can be defined type-specifically.

13.7 Programming an auxiliary function

Note

If no address extension is programmed, the address extension is implicitly set = 0.

Predefined auxiliary functions with the address extension = 0 always refer to the master spindle

of the channel.

Symbolic addressing

The values for the "address extension" and "value" parameters can also be specified symbolically.

The symbolic name for the address extension must then be stated in brackets.

Example:

Symbolic programming of the auxiliary function M3 (spindle right) for the 1st spindle:

; 1st spindle in the channel

DEF DREHRICHTUNG=3

; Clockwise rotation

N100 M[SPINDEL_NR]=DREHRICHTUNG

; in accordance with: M1=3

Note

If you use symbolic names to program an auxiliary function, the symbolic name is not

transferred when the auxiliary function is output to the PLC. The corresponding numerical value

is transferred instead.

Auxiliary functions without block change delay

Function

For auxiliary functions with parameterized and/or programmed output behavior, too:

• "Output duration one OB40 cycle (quick acknowledgment)"

• "Output before the motion" or "Output during the motion"

there may be drops in velocity in continuos-path mode (short traverse paths and high velocities).

This the system has to wait for acknowledgment of the auxiliary function by the PLC toward the

end of the block. To avoid these velocity drops, the block change can be made irrespective of

whether such auxiliary functions have been acknowledged:

Parameter assignment

Suppression of the block change delay with quick auxiliary functions is set via the machine data:

MD22100 $MC_AUXFU_QUICK_BLOCKCHANGE (block change delay with quick auxiliary

functions)

Value

Meaning

In the case of quick auxiliary function output to the PLC, the block change is delayed until

acknowledgment by the PLC (OB40).

In the case of quick auxiliary function output to the PLC, the block change is not delayed.

Boundary conditions

Synchronism of auxiliary functions that are output without a block change delay is no longer

ensured for the part program block in which they are programmed. In the worst case scenario,

acknowledgment comes one OB40 cycle and execution of the auxiliary function comes one OB1

cycle after the change to the next part program block.

M function with an implicit preprocessing stop

Function

Triggering a preprocessing stop in conjunction with an auxiliary function can be programmed

explicitly via the STOPRE part program command. Always triggering a preprocessing stop in M

function programming can be parameterized for each M function via the following machine

data:

MD10713 $MN_M_NO_FCT_STOPRE[<n>] (M function with preprocessing stop)

The user-defined M function M88 is intended to trigger a preprocessing stop.

• NC START to resume an interrupted part program

the auxiliary functions that are output at the start can be changed by the "Overstore" function.

13.13 Behavior during block search

Possible applications include:

• Addition of auxiliary functions after block search

• Restoring the initial state to position a part program

Types of auxiliary functions that can be overstored

The following types of auxiliary functions can be overstored:

• M (special function)

• S (spindle speed)

• T (tool number)

• H (aux. function)

• D (tool offset number)

• DL (additive tool offset)

• F (feed)

Duration of validity

An overstored auxiliary function, e.g. M3 (spindle right), is valid until it is overwritten by another

auxiliary function from the same auxiliary function group, by additional overstoring or by

programming in a part program block.

Behavior during block search

13.13.1

Auxiliary function output during type 1, 2, and 4 block searches

Output behavior

In the case of type 1, 2, and 4 block searches, the auxiliary functions are collected on the basis of

specific groups. The last auxiliary function in each auxiliary function group is output after NC-

START in a separate part program block before the actual reentry block, and has the following

output behavior:

• Output duration of one OB1 cycle (normal acknowledgement)

• Output prior to motion

Auxiliary function outputs to PLC

13.13 Behavior during block search

Output control

Whether or not the auxiliary function is output to the PLC after a block search can be configured

via bit 8 of the machine data:

• MD22080 $MC_AUXFU_PREDEF_SPEC[<n>]

(output behavior of predefined auxiliary functions)

where <n> = system function index (0 ... 32)

• MD22035 $MC_AUXFU_ASSIGN_SPEC[<n>]

(output behavior of user-defined auxiliary functions)

where <n> = auxiliary function index (0 ... 254)

• MD11110 $MN_AUXFU_GROUP_SPEC[<n>]

(output behavior of the auxiliary functions in a group)

where <n> = group index (0 ... 63)

Bit

Value

Meaning

Output during type 1, 2, and 4 block searches

No output during type 1, 2, and 4 block searches

This behavior does not affect the display and does not affect variables $AC_AUXFU_STATE[<n>],

$AC_AUXFU_VALUE[<n>], and $AC_AUXFU_EXT[<n>].

The auxiliary functions are always regarded as collected after a block search, even though they

are not output to the PLC.

During collection, an auxiliary function that is not output after a block search also overwrites an

auxiliary function whose bit 8 is not set.

The user can scan the collected auxiliary functions after a block search and, under certain

circumstances, output them again by means of the subprogram or synchronized actions.

Note

The following auxiliary functions are not collected:

• Auxiliary functions which are not assigned to any auxiliary function group.

• Auxiliary functions which are assigned to the first auxiliary function group.

Overstorage of auxiliary functions

After completion of a block search, the collected auxiliary functions are ouput on the next NC-

START. If it is necessary to output additional auxiliary functions, they can be added via the

"Overstore" function (see Section "Response to overstore (Page 737)").

M19 behavior (position spindle)

After a block search, the last spindle positioning command programmed with M19 is always

carried out, even if other spindle-specific auxiliary functions are programmed between the part

program with M19 and the target block. Setting the necessary spindle enables must therefore

be derived from the interface signals of the traverse commands in the PLC user program:

DB31, ... DBX64.6/64.7 (traversing command minus/plus)

13.13 Behavior during block search

In this case, the spindle-specific auxiliary functions M3, M4, and M5 are not suitable because

they might not be output to the PLC until after the spindle positioning.

For detailed information on the block search, see Section "Mode group, channel, program

operation, reset response (Page 25)".

13.13.2

Assignment of an auxiliary function to a number of groups

Function

User-defined auxiliary functions can also be assigned to multiple groups via the group

assignment (MD22000 $MC_AUXFU_ASSIGN_GROUP). During the block search these auxiliary

functions are collected for all the configured groups.

Note

Predefined auxiliary functions can only be assigned to one group.

Example

The DIN includes the following M-commands for coolant output:

• M7: Coolant 2 ON

• M8: Coolant 1 ON

• M9: Coolants 1 and 2 OFF

Consequently, both coolants can also be active together:

• If M7 and M8 are collected in two separate groups (e.g. groups 5 and 6)

• If M9 has to be assigned to these two groups, e.g.

- Group 5: M7, M9

- Group 6: M8, M9

MD11100 $MN_AUXFU_MAXNUM_GROUP_ASSIGN = 4

Time stamp of the active M auxiliary function

When outputting collected auxiliary functions following a block search, attention must be paid

to the sequence during collecting. For this reason, each group is assigned a time stamp which

can be queried on a group-specific basis by way of the system variable below:

$AC_AUXFU_M_TICK[<n>] (time stamp of the active M auxiliary function)

The following predefined procedure is provided to simplify the process of determining the

The function determines the sequence in which the M auxiliary functions, which have been

collected on a group-specific basis, are output for the predefined M codes. The sequence is

determined from the collection times $AC_AUXFU_M_TICK[<n>] (see Section "Time stamp of

the active M auxiliary function (Page 741)").

A particular M code is only taken into account once, even if it belongs to more than one group.

If the number of relevant M commands is less than or equal to 0, all the collected M codes are

output. The number of relevant M commands is limited to 64.

M commands for coolant output:

• M7: Coolant 2 ON

• M8: Coolant 1 ON

• M9: Coolants 1 and 2 OFF

During block searches, the auxiliary functions are collected on the basis of specific groups. The

last auxiliary function in an auxiliary function group is output to the PLC following a block search:

• Group 5: M7

• Group 6: M9

If they are output in the sequence M7 → M9, no coolant is then active. However, coolant 2 would

be active during the execution of the program. Therefore, the correct output sequence for the

M auxiliary functions is determined with an ASUP which contains the predefined procedure

13.13.5

Output suppression of spindle-specific auxiliary functions

Function

In certain situations, such as a tool change, it may be necessary not to output the spindle-

specific auxiliary functions collected during the block search in action blocks, but to delay

output, for example, until after a tool change. The automatic output of the spindle-specific

auxiliary functions after a block search may be suppressed for this purpose. Output can then be

performed manually later by overstoring or by an ASUP.

Parameterization

Suppression of the automatic output of the spindle-specific auxiliary functions after a block

search is set via machine data:

MD11450 $MN_SEARCH_RUN_MODE (behavior after a block search)

Bit

Value

Meaning

The output of the spindle-specific auxiliary functions is performed in the action blocks.

Output of the auxiliary functions is suppressed in the action blocks.

Note

The contents of the system variables $P_S, $P_DIR and $P_SGEAR may be lost after block search

due to synchronization operations.

Explanation of example

If the number of spindles is known, outputs of the same type can be written in one part program

block to reduce program runtime.

Output of $P_SEARCH_SDIR should be made in a separate part program block because spindle

positioning or switchover to axis mode in conjunction with the gear change can cause an alarm.

If the ASUP which has been started is ended with REPOSA, spindle 1 remains at position 111

degrees, while spindle 2 is repositioned at position 77 degrees.

If a different response is required, the program sequence for block search (for example) "N05

M3 S..." and "N30 SPOS[2] = IC(...)" requires special treatment.

Whether block search is active can be ascertained in the ASUP via the system variable

$P_SEARCH.

$P_SEARCH==1 ; Block search active

In the case of incremental positioning after speed control operation, the path to be traversed is

defined but, in some cases, the final position reached only becomes known during positioning.

This is the case, for example, during position calibration on crossing the zero mark when

switching on position control. For this reason, the distance programmed after the zero position

is accepted as the REPOS position (REPOSA in the ASUP).

Collected S values

Basic functions

Function Manual, 10/2020, 6FC5397-2GP40-0BA1

745

Auxiliary function outputs to PLC

13.13 Behavior during block search

The meaning of an S value in the part program depends on the feed type that is currently active:

G93, G94, G95, G97, G971:

The S value is interpreted as the speed

G96, G961:

The S value is interpreted as a constant cutting rate

If the feed operation is changed (e.g. for a tool change) before output of the system variable

$P_SEARCH_S, the original setting from the target block in the part program must be restored to

avoid use of the wrong type of feed.

Collected direction of rotation

For output of the direction of rotation, the system variable $P_SEARCH_SDIR is assigned default

value "-5" at the start of the block search. This value has no effect on output.

This ensures that the last spindle operating mode is retained for a block search across program

sections in which spindles are not programmed with a direction of rotation, positioning or axis

mode.

The programming of M19, SPOS, and SPOSA is collected as "M-19" (internal M19) in the system

variables $P_SEARCH_SDIR as an alternative to M3, M4, M5, and M70.

For the output of "M-19", the positioning data is read internally from the system variables

$P_SEARCH_SPOS and $P_SEARCH_SPOSMODE. Both system variables can also be written to, in

order, for example, to make corrections.

Note

Because of the assignments described above (e.g. M[<n>] = $P_SEARCH_SDIR[<n>]), the values

"-5" and "19" generally remain hidden from the user and only have to be observed in the case of

special evaluation of the system variables in the ASUP.

The global list is structured on the basis of the sequence in which the search target was found.

It is intended to be used as a system proposal for auxiliary functions to be output in the following

ASUP at the end of SERUPRO. If an auxiliary function is not to be output, the corresponding group

index is to be set to "0".

Behavior regarding spindle auxiliary functions

Following the start of the block search, all the channels collect the auxiliary functions in the

channel variables on a group-specific basis. In order to perform a far-reaching restoration of the

spindle state in the SERUPRO target block using the collected auxiliary functions, the last active

auxiliary function in any group of spindle auxiliary functions must characterize the state of the

spindle in the target block. In the case of transitions in spindle states, obsolete auxiliary

functions are deleted or, if necessary, implicit auxiliary functions are entered.

All the spindle auxiliary functions from the global auxiliary function list must correspond to the

spindle states achieved in the target block to enable the auxiliary functions to be processed

when the list is output and to ensure that no alarms or unintended spindle states are requested

which could prevent the continuation of the part program.

13.13 Behavior during block search

This affects the groups of auxiliary functions for any spindle configured in the system, whereby

the spindle number corresponds to an auxiliary function's address extension.

Group b:

M40, M41, M42, M43, M44, M45

Group c:

Deleting obsolete auxiliary functions

In the functions below, the auxiliary functions from group a are deleted for the spindle

concerned:

• For the following spindle when a generic coupling, such as COUPON, TRAILON, EGON, etc. is

switched on

Generating implicit auxiliary functions from group a

In the functions below, the auxiliary functions from group a are generated implicitly for the

spindle concerned:

• For the following spindle when the synchronous spindle coupling is switched off

- COUPOF generates M3, M4 and S or M5 in the main run depending on the coupling

situation.

- COUPOF(S<n>, S<m>, POS) and COUPOFS(S<n>, S<m>, POS, POS) generate M3, M4 and

- COUPOFS generates M5 in the main run.

- COUPOFS(S<n>, S<m>, POS) generates M19 in the main run.

The implicit M19 ("SPOS[<address extension>] = IC(0)" in the ASUP) activates the

positioning mode without a traversing motion.

• M70 is generated during a traversing motion as an axis or during the transition to axis mode

by selecting a transformation during which the spindle enters as an axis.

• M5 is generated during SPCOF.

Note

Within the context of the "axis interchange" and "axis container rotation" functions, the auxiliary

functions for programming the spindle must always be specified in a way which ensures

compatibility with the actual (motor) state during interchange/rotation. A distinction is made

here between the axis interchange and axis container mechanisms.

Example of axis container rotation:

An axis container has four spindles, each assigned to a separate channel (1 - 4). M3 S1000 is

always programmed in channel 1, and an axis container rotation is then executed. The other

channels do not perform any spindle programming. Following the third axis container rotation

and the fourth spindle programming, M3, all four spindles rotate clockwise at a speed of 1000

rpm. If the end of the SERUPRO now lies within this range, every ASUP for a channel is expected

to contain an M3 S1000 for the local spindle.

During interchange however, the collected auxiliary functions may only be assigned to the

channel where the spindle is currently located.

13.13 Behavior during block search

Cross-channel auxiliary function

An auxiliary function can also be collected on a cross-channel basis in the global auxiliary

function list in the case of type 5 block searches (SERUPRO). Only the last auxiliary function

collected from this group (highest counter state) is entered in the global list.

The appropriate configuring is performed with the following machine data:

• MD22080 $MC_AUXFU_PREDEF_SPEC[<n>], Bit 11

(output behavior of predefined auxiliary functions)

where <n> = system function index

• MD22035 $MC_AUXFU_ASSIGN_SPEC[<n>], Bit 11

(output behavior of user-defined auxiliary functions)

where <n> = auxiliary function index

• MD11110 $MN_AUXFU_GROUP_SPEC[<n>], Bit 11

(output behavior of the auxiliary functions in a group)

where <n> = group index

Bit

Value

Meaning

Channel-specific collection

Cross-channel collection

The spindle auxiliary functions are filtered out beforehand at the end of the block search

depending on the spindle state. The channel data is updated accordingly. The global auxiliary

function list can be processed sequentially in the ASUPs at the end of the SERUPRO, and the

sorted auxiliary functions can be output with channel synchronization.

Querying the last auxiliary function collected

The index of the last auxiliary function collected in the global list can be queried using the system

variable $AN_AUXFU_LIST_ENDINDEX.

13.13.7

ASUB at the end of the SERUPRO

Function

After completing the block search with the program test (SERUPRO), before starting the

subsequent processing, the auxiliary functions collected during the block search must be

output. For this purpose, during the block search, the auxiliary functions are collected in a global

list. The SERUPRO end ASUPs generate the corresponding part program blocks channel-specific

from this list. This ensures that the collected auxiliary functions can be output both channel-

specific as well as cross-channel in the correct sequence. A fully functional SERUPRO end ASUP

is a component of the NC software.

Users/machinery construction OEMs can change the SERUPRO end ASUP. The subsequently

described functions support processing the global list of auxiliary functions and generating the

part program blocks required for synchronized auxiliary function output.

13.13 Behavior during block search

Function AUXFUSYNC(...)

Function:

The function AUXFUSYNC generates a complete part program block as string from the global list

of auxiliary functions at each call. The part program block either contains auxiliary functions or

commands to synchronize auxiliary function outputs (WAITM, G4, etc.).

The function triggers a preprocessing stop.

Syntax:

PROC AUXFUSYNC(VAR INT <NUM>, VAR INT <GROUPINDEX>[10], VAR

STRING[400] <ASSEMBLED>)

Parameters:

<NUM>:

Contains information about the part program block, supplied in param-

eter <ASSEMBLED> or the auxiliary functions contained in it.

Value range: -1, 0, 1 ... 10

Val- Meaning

≥1

Number of auxiliary functions contained in the part program

block

Part program block without auxiliary functions, e.g. WAITM, G4

-1

End identifier. The global list of auxiliary functions has been com-

pletely processed for the actual channel.

<GROUP INDEX>:

Contains the indices of the auxiliary function groups contained in the

part program block. With index = number of the auxiliary function group

- 1

<ASSEMBLED>:

Contains the complete part program block for the channel-specific SER-

UPRO end ASUP as string.

Further information:

If auxiliary functions were collected via a synchronized action, two NC blocks are generated. One

NC block to output the auxiliary functions. An executable NC block via which the NC block is

transported to the main run to output the auxiliary functions:

1. Output of the auxiliary functions via synchronized action, e.g.: WHEN TRUE DO M100 M102

2. Executable NC block, e.g.: G4 F0.001

Function AUXFUDEL(...)

Function:

The function AUXFUDEL deletes the specified auxiliary function from the global list of auxiliary

functions channel-specific for the calling channel. Deletion is realized by setting the

corresponding group index ...GROUPINDEX[n] to 0.

The function must be called before calling AUXFUSYNC.

The function triggers a preprocessing stop.

Parameters:

<TYPE>:

Type of auxiliary function to be deleted

<EXTENSION>:

Address extension of the auxiliary function to be deleted

<VALUE>:

Value of auxiliary function to be deleted

<GROUP>:

Number of the auxiliary function group

Function AUXFUDELG(...)

Function:

The function AUXFUDELG deletes all auxiliary functions of the specified auxiliary function group

from the global list of auxiliary functions channel-specific for the calling channel. Deletion is

realized by setting the corresponding group index ...GROUPINDEX[n] to 0.

The function must be called before calling AUXFUSYNC.

The function triggers a preprocessing stop.

Syntax:

PROC AUXFUDELG(INT <GROUP>)

Parameters:

<GROUP>:

Number of the auxiliary function group

Multi-channel block search

NOTICE

Multi-channel block search and AUXFUDEL / AUXFUDELG

If, for a multi-channel block search in the SERUPRO end ASUPs, auxiliary functions with

AUXFUDEL / AUXFUDELG are deleted from the global list of auxiliary functions, before calling

the AUXFUSYNC function, the channels involved must be synchronized. The synchronization

ensures that before calling the AUXFUSYNC, all delete requests are processed and a consistent

list is available.
