Mode group, channel, program operation, reset response

3.15 Process Datashare - output to an external device/file

<ExtDev>:

Parameter 2: Symbolic identifier for the external device/file to be opened

Type:

STRING

The symbolic identifier comprises:

1. the logical device name

2. where relevant, followed by a file path (attached using "/").

The following logical device names have been defined:

"LOCAL_DRIVE":

Local CF card (pre-defined)

"CYC_DRIVE":

Reserved drive name for use in SIEMENS cycles (pre-de-

fined)

"/dev/ext/1", ...

Available network drives

"/dev/ext/9":

Note:

It is necessary to configure in the extdev.ini file!

"/dev/cyc/1",

Reserved drive names for use in SIEMENS cycles

"/dev/cyc/2":

Note:

It is necessary to configure in the extdev.ini file!

File path:

• A file path must be specified for "LOCAL_DRIVE" and "CYC_DRIVE" e.g.

"LOCAL_DRIVE/my_dir/my_file.txt"

• The logical device names "/dev/ext/1...9" and "/dev/cyc/1...2" can be configured:

- To already refer to a file, in which case only the logical device names may be

specified, e.g.:

"/dev/ext/4"

- Or to a directory, in which case a file path must be specified, e.g.:

"/dev/ext/5/my_dir/my_file.txt"

Note:

For the logical device names "/dev/ext/1...9", "/dev/v24" and "/dev/cyc/1...2" up-

percase/lowercase is ignored; uppercase/lowercase is significant for specifying a

path to a file. Only uppercase letters are permissible for "LOCAL_DRIVE" and

"CYC_DRIVE".

<SyncMode>:

Parameter 3: Processing mode for the WRITE commands to this device/file

Type:

STRING

Values:

"SYN":

Synchronous writing

Program execution is stopped until the write operation

has been completed.

Successfully completing the synchronous write opera-

tion can be checked by evaluating the error variables of

the WRITE command.

"ASYN":

Asynchronous writing

Program execution is not interrupted by the WRITE com-

mand.

Note.

In this mode, the result variable of the WRITE command

does not provide any information and always has the

value 0 (no error). In this particular mode, there is no

certainty that the WRITE command was successful.

<AccessMode>:

Parameter 4: Usage mode for this device/file

Type:

STRING

Values:

"SHARED":

Device/file is requested in the "shared" mode. Other

channels can also use the device, i.e. also open in this

mode.

"EXCL":

Device/file is exclusively used in the channel; no other

channel can use the device.

<WriteMode>:

Parameter 5: Write mode for the WRITE commands to this file/device (optional)

Type:

STRING

Values:

"APP":

Attaching

The file is always kept regarding its contents; write calls

are attached at the end.

"OVR":

Overwrite

The contents of the file are deleted and re-generated

using the subsequent write calls.

Note:

Using this parameter, the write mode configured in the extdev.ini file cannot be

overwritten. In the case of a conflict, then the EXTOPEN call is acknowledged with

error.

WRITE:

Pre-defined procedure to write output data

EXTCLOSE:

Pre-defined procedure to close an external device/file that has been opened

<Result>:

Parameter 1: Result variable

Type:

INT

Values:

No error

Invalid external path has been programmed

Error when closing the external device

<ExtDev>:

Parameter 2: Symbolic identifier for the external device/file description to be

closed, see EXTOPEN!

Note:

The identifier must be identical to the identifier specified in the EXTOPEN call!

Supplementary conditions

Effect on continuous path mode

The EXTOPEN, WRITE and EXTCLOSE commands trigger a preprocessing stop and therefore

interrupt the continuous path mode.

Behavior during block search

During "block search with calculation" with WRITE, no output is made. However, the EXTOPEN

and EXTCLOSE commands are collected and set active with NC start after the search target was

reached. The following WRITE commands therefore find the same environment as for the normal

program processing.

For a block search with calculation in the (SERUPRO) "Program test" mode, EXTOPEN, WRITE and

EXTCLOSE are executed just the same as for normal program processing.

• MD20112, bit 4 = 1

• MD20112, bit 5 = 1

Note

MD20110/MD20112, bit 5 and bit 6

If MD20110/MD20112 are parameterized so that tool length compensation or a frame is

active on a part program start in the automatic or MDI mode, the first programming of the

axes must use absolute measurements (because of the traversing of the offset).

Exception: With MD42442/MD42440 the offsetting process for G91 is suppressed.

3.16.2

Tool withdrawal after POWER ON with orientation transformation

Function

If a part program with a machining operation with tool orientation is aborted due to a power

failure or reset, it is possible to select the previously active transformation and generate a frame

in the direction of the tool axis after the control has run up (power on). The tool can then be

retracted in JOG mode by means of a retraction movement towards the tool axis.

Requirement

The active measuring systems must have a machine reference for all the machine axes involved

in the transformation. See Function Manual "Axes and Spindles", Section "Automatic restoration

of the machine reference".

• MD20110 $MC_RESET_MODE_MASK, bit 0 = 1

• MD20110 $MC_RESET_MODE_MASK, bit 7 = 1

See also Section "System settings for power-up, RESET / part program end and part program start

(Page 207)".

Programming

Wait for machine reference WAITENC

With the command WAITENC, the system waits channel-specific in a program until there is a valid

machine reference for all the active measuring systems of the parameterized axes. See the

"Requirement" section above. The parameter assignment of the axes is performed via:

MD34800 $MA_WAIT_ENC_VALID = 1

Application

In the user program (…/_N_CMA_DIR/_N_PROG_EVENT_SPF) to be called event-controlled when

running up (requirement: MD20108 bit 3 = 1), the system must wait using the command

WAITENC until the valid axis positions are available.

A frame that positions the tool axis in the direction of the X, Y or Z axis can then be generated

using the NC language command TOROTX/TOROTY/TOROTZ.

Example

Orientation transformation and orientation axes with incremental encoders.

Meaning:

MD10720 $MN_OPERATING_MODE_DEFAULT [ 0 ] = 6

AUTOMATIC mode

For automatic execution of programs in the AUTOMATIC mode, all the machine axes, whose

actual position of the active measuring system has been restored, must be referenced.

MDI mode and overstore

In the MDI mode and for the overstore function, machining can also be performed, without

referencing the axes, with restored positions. To do this, NC start with restored positions must

be enabled explicitly for a specific channel:

MD20700 $MC_REFP_NC_START_LOCK = 2

Boundary condition

Axes with incremental encoders and without actual value buffering

It is to be assumed that axes with incremental encoders and without actual value buffering are

clamped with sufficient speed in the event of a power failure to prevent them drifting from their

last position setpoint.

Replacing functions by subprograms

3.17.1

Overview

Function

User-specific auxiliary functions (e.g. M101) do not trigger any system functions. They are only

output to the NC/PLC interface. The functionality of the auxiliary function must be implemented

by the user / machine manufacturer in the PLC user program. A description will be provided as

to how a user-specific subprogram call can be configured (replacement subprogram) instead of

the output to NC/PLC interface, which is the default setting.

Function M101 is then still programmed in the part program. However, when executing the part

program, the substitute subprogram is called. Therefore, the NC replaces the function by a

subprogram call. This results in the following advantages:

• When adapting to the production process, an existing, tested and proven part program can

still be used, unchanged. The changes required are then shifted into the user-specific

subprograms.

• The functionality can be implemented within the substitute subprogram with the full

functional scope of the NC language.

• The communication overhead between NC and PLC is not required.

Functions that can be replaced

The following functions can be replaced by subprograms:

Auxiliary functions

Switching functions

Tool selection

TCA

Tool selection independent of the tool status

Tool offset

Additive tool offset

Spindle-related functions during active synchronous spindle coupling

M40

3.17.2

Replacement of M, T/TCA and D/DL functions

3.17.2.1

Replacement of M functions

General Information

The following conditions are applicable for replacing the M functions:

• Per block only one M function is replaced.

• A block in which an M function is to be replaced, must not contain the following elements:

- M98

- Modal subprogram call

- Subprogram return

- Part program end

• M functions that trigger system functions must not be replaced by a subprogram (see Section

"Non-replaceable M functions").

Parameterization

M function and subprogram

M functions and the replacement subprograms are parameterized in the following machine

data:

• MD10715 $MC_M_NO_FCT_CYCLE[<Index>] = <M function number>

• MD10716 $MC_M_NO_FCT_CYCLE_NAME[<Index>] = "<subprogram name>"

The M function and the corresponding replacement subprogram are connected through the

same index.

Example: M function M101 is replaced by subprogram SUB_M101 and M function M102 by

SUB_M102:

MD10715 $MC_M_NO_FCT_CYCLE[ 0 ]

= 101

MD10716 $MC_M_NO_FCT_CYCLE_NAME[ 0 ]

= "SUB_M101"

MD10715 $MC_M_NO_FCT_CYCLE[ 1 ]

= 102

MD10716 $MC_M_NO_FCT_CYCLE_NAME[ 1 ]

= "SUB_M102"

System variable for transferring information

For a freely selectable M function, information regarding the M function that has been replaced

and additional functions (T, TCA, D, DL) for evaluation in the replacement subprogram are made

available via the system variable (see Section "System variable (Page 220)"). The data contained

in the system variables refers to the block in which the M function to be replaced is programmed.

The M function is selected with the index of machine data MD10715

$MC_M_NO_FCT_CYCLE[<Index>] in which the M function to be replaced has been

parameterized:

3.17 Replacing functions by subprograms

MD10718 $MC_M_NO_FCT_CYCLE_PAR = <Index>

Note

For an M function replacement with transfer of information via system variable, the address

extension and function value of the M function must be programmed as constant values.

Permissible programming:

• M<function value>

• M=<function value>

• M[<address extension>]=<function value>

Illegal programming:

• M=<variable1>

• M[<variable2>]=<variable1>

Programming

Rules for replacing M functions:

• The replacement subprogram is called at the block end

• Within the replacement subprogram, no M functions are replaced

• In an ASUB, the M function is also replaced if the ASUB was started within the replacement

subprogram.

M functions that cannot be replaced

The following M functions trigger system functions as pre-defined auxiliary functions and

must not be replaced by a subprogram:

• M0 ... M5

• M17, M30,

• M19

• M40 ... M45

• M98, M99 (only for MD18800 $MN_MM_EXTERN_LANGUAGE ≠ 0)

User-specific M functions parameterized via machine data must also not be replaced by a

subprogram as they also trigger system functions.

Replacing T/TCA and D/DL functions

Supplementary conditions

For replacing functions T, TCA, D and DL, the following supplementary conditions apply:

• A maximum of one function replacement is active per block.

• A block with the function replacement must not contain the following elements:

- M98

- Modal subprogram call

- Subprogram return

- Part program end

• If the multitool slot number is programmed with address MTL for the multitool select with

T = slot number, the T replacement also replaces the MTL address. The programmed values

can be queried in the replacement subprogram using the $C_MTL_PROG and $C_MTL system

variables.

3.17 Replacing functions by subprograms

Note

It is recommended that the same subprogram is used to replace T, TCA and D/DL functions.

Parameterization: Behavior regarding D or DL function with simultaneous T function

When D or DL and T functions are simultaneously programmed in a block, the D or DL number

is either transferred as parameter to the replacement subprogram or the D or DL function is

executed before calling the replacement subprogram. The behavior is configurable via:

MD10719 $MN_T_NO_FCT_CYCLE_MODE (parameterization of the T function replacement)

Bit

Value

Meaning

The D or DL number is available in the subprogram in the form of a system variable (initial

state).

The D or DL number is calculated directly in the block.

Note:

This function is only active if the tool change was configured with M function:

MD22550 $MC_TOOL_CHANGE_MODE = 1

otherwise the D or DL values are always transferred.

System variable for transferring information

The replacement subprogram is provided with all of the information relevant to the functions

programmed in the block via system variables (see Section "System variable (Page 220)").

The data contained in the system variables refers to the block in which the function to be

replaced was programmed.

Parameterization: Time that the replacement subprogram is called

The call time of the replacement subprogram is set via:

MD10719 $MN_T_NO_FCT_CYCLE_MODE, bit 1 and bit 2

Bit 2

Bit 1

Time that the replacement subprogram is called

At the end of the block

After the replacement subprogram has been executed, the interpretation is resumed

with the program line following the line that triggered the replacement operation.

At block start

After the replacement subprogram has been executed, the program line, which re-

sulted in the replacement subprogram being called, is interpreted. The T address and

the D or DL address and the M function for the tool change are no longer processed.

At block start and block end

The replacement program is called twice.

Replacement of spindle functions

3.17.3.1

General information

Function

When a coupling is active the following spindle functions can be replaced for leading spindles:

• M40: Automatic gear stage change

• M41 ... M45 Programmed gear stage change

• SPOS, SPOSA and M19: Spindle positioning

Boundary conditions

• To replace a spindle function, the following conditions must be met:

- The programmed spindle must be the leading spindle of an active coupling.

- Leading and following spindle are located in the same channel. This is only detected if the

leading spindle is located in the channel in which the coupling was closed. If the leading

spindle is changed to another channel, a gear stage change or positioning of this spindle

does not call the replacement subprogram.

- A programmed gear stage change must result in a real gear stage change. For this

purpose, the programmed and active gear stage must differ.

• In a block, only one spindle function can be replaced. Multiple replacements lead to the

termination of the program processing. The spindle functions, which are to be replaced,

must then be distributed over several blocks.

Parameterization

Replacement active, subprogram call is made at the block start

Replacement active, subprogram call is made at the block end

Block processing

If the replacement subprogram is called at the block start, after processing the replacement

subprogram, the block that initiated the call is processed. The replaced commands are no longer

processed.

If the replacement subprogram is called at the block end, the block that initiated calling the

replacement subprogram is first processed without the commands to be replaced. The

replacement subprogram is then subsequently called.

3.17.3.2

Replacement of M40 - M45 (gear stage change)

Time that the subprogram is called

• M40

The time of the call cannot be set. The replacement subprogram is always called at the block

• M41 ... M45

The call time depends on the configured output behavior of the auxiliary function to the PLC

(see below MD22080):

- Output before or during motion: Subprogram call at the start of the block.

- Output after motion: Subprogram call at the end of the block

System variable to transfer information

The replacement subroutine is provided with all of the information relevant to the functions

programmed in the block via system variables (see Chapter "System variable (Page 230)"). The

data refer exclusively to the block, in which the function to be replaced has been programmed.

3.17.3.3

Replacement of SPOS, SPOSA, M19 (spindle positioning)

Function

When a coupling is active, the positioning commands (SPOS, SPOSA or M19) of a leading spindle

are replaced by calling a user-specific subprogram (replacement subprogram).

Application example

When machining workpieces in parallel on a double-spindle machine, the spindles are coupled

through a coupling factor not equal to 1. When changing the tool, they must be brought to the

same position. The replacement subprogram opens the coupling, separately positions the

spindles at the tool change position and then recloses the coupling.

3.17.4

Properties of the subprograms

General rules

• The subprogram called when making the replacement can contain the command PROC and

the attribute SBLOF and DISPLOF.

• The replacement is also made in the ISO language mode. However, the replacement

subprograms are exclusively processed in the standard language mode (Siemens). There is

an implicit switchover into the standard language mode. The original language mode is

reselected with the return jump from the replacement subprogram.

• System variables are exclusively used to transfer information to the replacement

subprogram. Transfer parameters are not possible.

• The behavior for a single block and attribute SBLOF depends on the setting in:

MD10702 IGNORE_SINGLEBLOCK_MASK, bit 14 (prevent single-block stop)

Value

Meaning

The replacement subprogram behaves like a "normal" subprogram:

• Return jump with M17: Stop at the end of the subprogram

Note

The output of the M function at the PLC depends on:

MD20800 $MC_SPF_END_TO_VDI, bit 0 (subprogram end to PLC)

- Bit 0 = 0: No output

- Bit 0 = 1: M17 is output to the PLC.

• Return jump with RET: No stop at the end of the replacement subprogram

In the block, in which the replacement subprogram is called, only one stop is made. Regardless

of whether:

• The subprogram was called at the block start and/or at the block end

• Other subprograms are called in the subprogram

• The subprogram is exited with M17 or RET

The single-block stop takes place for the replacement of M functions at the end of the replace-

ment subprogram.

For the replacement of T and D/DL functions, the time of the single-block stop depends on when

the subprogram is called:

• Call at block start: Single-block stop at the end of the block

• Call at the block end: Single-block stop at the end of the replacement subprogram

Basic functions

236

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

Mode group, channel, program operation, reset response

3.17 Replacing functions by subprograms

• For replacement subprograms with the attribute DISPLOF in the block display, the program

line is displayed as actual block, which resulted in the subprogram being called.

• In the replacement subprogram, areas or the complete replacement subprogram can be

protected against interruptions, such as NC stop, read-in inhibit etc., using the DELAYFSTON

and DELAYFSTOF commands.

• Replacements do not occur recursively, i.e. the function that has led to the replacement

subprogram call is no longer replaced if it is programmed again in the replacement

subprogram.

Output of auxiliary functions to PLC

When replacing auxiliary functions, calling the replacement subprogram does not initiate that

the auxiliary function is output to the PLC. The auxiliary function is only output if the auxiliary

function is reprogrammed in the replacement subprogram.

Behavior during block search

The replacement subprogram is also called in the block search modes "Block search with

calculation" and "Block search with calculation in the program test mode" (SERUPRO). Any

special features must be implemented in the replacement subprogram using the system

variable: $P_SEARCH, $AC_SERUPRO.

Regarding collecting actions for "block search with calculation", replacement subprograms

behave just like "normal" subprograms.

3.17.5

Restrictions

• Function replacements are not permitted in:

- Synchronized actions

- Technology cycles

• There must be no blockwise synchronized actions in front of a block that contains functions

at the beginning to be replaced. See the paragraph below "Example for: Non-modal

synchronized actions".

• Only the actions required for the respective replacements can be performed in the

replacement subprogram.

• In a block, in which the replacement subprogram is called at the block end, the following

should be observed:

- No modal subprogram call should be active

- No subprogram return jump should be programmed

- No program end should be programmed

Note

The controller does not monitor whether the function to be replaced has been realized in

the replacement subprogram.

If, in block N1010, the function M43 initiates that a replacement subprogram is called,

machining is interrupted and an alarm is output.

3.18

Renaming/locking NC commands

Function

The machine manufacturer or user can change the names of existing NC commands with the

"Rename/lock NC commands" function.

Application

The function can be used for the following purposes:

• Improve the readability of part programs

• Lock NC commands

• User-specific extension of NC functions

Parameterization

The renaming/locking of NC commands is made via the machine data:

MD10712 $MN_NC_USER_CODE_CONF_NAME_TAB[<n>] (list of reconfigured NC codes)

An even index [<n>] contains the original name of the command. The following uneven index

contains the new name of the command.

An empty string ("") as new name means that there is no new name for the command.

Consequently, the command is locked and can no longer be programmed.

Changes of MD10712 become effective during the control system startup.

Example

Rename command G00 and deactivate G01

MD10712 $MN_NC_USER_CODE_CONF_NAME_TAB[0] = "G00"

MD10712 $MN_NC_USER_CODE_CONF_NAME_TAB[1] = "RAPIDTRAVERSE"

MD10712 $MN_NC_USER_CODE_CONF_NAME_TAB[2] = "G01"

MD10712 $MN_NC_USER_CODE_CONF_NAME_TAB[3] = ""

After activation with Power On, rapid traverse can no longer be programmed with the G00

command, but only with the RAPIDTRAVERSE command. G01 can no longer be programmed.

3.19

Program runtime / part counter

Information on the program runtime and workpiece counter is provided to support the machine

tool operator.

This information can be processed as system variables in the NC and/or PLC program. This

information is also available to be displayed on the operator interface.

3.19.1

Program runtime

3.19.1.1

Function

The "Program runtime" function provides various timers to monitor technological processes,

which can be read into the part program and into synchronized actions via system variables.

There are two types of timers:

1. Standard timers

Standard timers are always active

2. Timers that can be activated

Timers that can be activated must be activated via machine data.

Standard timers

Time since the last control power-up

System variable

Meaning

$AN_SETUP_TIME

Time since the last control power-up with default values in minutes.

Is automatically reset to "0" in each control power-up with default values.

$AN_POWERON_TIME

Time since the last normal control power-up ("warm restart") in minutes.

Is automatically reset to "0" in each normal control power-up.

239

Mode group, channel, program operation, reset response

3.19 Program runtime / part counter

Program runtime

The timers to measure the program runtimes are only available in AUTOMATIC mode.

System variable (channel-specific)

Description

$AC_ACT_PROG_NET_TIME

Actual net runtime of the current program in seconds

Net runtime means that the time, in which the program was stopped, has been

deducted.

If, in the AUTOMATIC operating mode, a part program is restarted from the RESET

channel state, then $AC_ACT_PROG_NET_TIME is automatically reset to "0".

Additional properties:

• The reset button does not reset $AC_ACT_PROG_NET_TIME back to "0", but

rather only stops the timer.

• When starting an ASUB, $AC_ACT_PROG_NET_TIME is set to "0" and also

counts the runtime of the ASUB. At the end of an ASUB, it behaves just the

same as for the RESET button: The timer is only held, but is not set to "0".

• $AC_ACT_PROG_NET_TIME is not reset when starting an event-controlled

program (PROG_EVENT).

The program runtime is only counted further if it involves a start, M30 or a

search PROG_EVENT.

• The behavior of $AC_ACT_PROG_NET_TIME for GOTOS and override = 0% can

be parameterized using MD27850 (refer to Section "Parameterization")

Tip:

With $AC_PROG_NET_TIME_TRIGGER, $AC_ACT_PROG_NET_TIME can be manip-

ulated further.

$AC_OLD_PROG_NET_TIME

Net runtime in seconds of the program that has just been correctly ended

"Correctly ended" means that the program was not interrupted with RESET, but

instead ended properly with M30.

If a new program is started, $AC_OLD_PROG_NET_TIME remains unscanned,

till M30 is reached again.

Additional properties:

• $AC_OLD_PROG_NET_TIME is set to "0" if the currently selected program is

edited.

• $AC_OLD_PROG_NET_TIME is not changed at the end of an ASUB or an event-

controlled program (PROG_EVENT).

Tip:

The implied copying process of $AC_ACT_PROG_NET_TIME after

$AC_OLD_PROG_NET_TIME takes place only when $AC_PROG_NET_TIME_TRIG-

GER is not written.

3.19 Program runtime / part counter

System variable (channel-specific)

Description

$AC_OLD_PROG_NET_TIME_COUNT

Changes to $AC_OLD_PROG_NET_TIME

After POWER ON, $AC_OLD_PROG_NET_TIME_COUNT is at "0".

$AC_OLD_PROG_NET_TIME_COUNT is always increased if the control has newly

written to $AC_OLD_PROG_NET_TIME.

If the user terminates the running program with RESET,

$AC_OLD_PROG_NET_TIME and $AC_OLD_PROG_NET_TIME_COUNT remain un-

changed.

With $AC_OLD_PROG_NET_TIME_COUNT it can thus be ascertained, whether

$AC_OLD_PROG_NET_TIME was written.

Example:

If two programs running consecutively have the same runtime and were ended

correctly, then the user can identify this via the changed value in

$AC_OLD_PROG_NET_TIME_COUNT.

$AC_PROG_NET_TIME_TRIGGER

Trigger for the selective measurement of program sections.

The function is triggered by the writing of the value to the variable:

Val-

Function

Not active

Terminates the measurement

• $AC_OLD_PROG_NET_TIME = $AC_ACT_PROG_NET_TIME

• $AC_ACT_PROG_NET_TIME = 0 and then continues to run

Starts the measurement

• $AC_ACT_PROG_NET_TIME = 0

• $AC_OLD_PROG_NET_TIME is not changed

Stops the measurement

• $AC_OLD_PROG_NET_TIME is not changed

• $AC_ACT_PROG_NET_TIME is not changed

Continues the stopped measurement

• $AC_ACT_PROG_NET_TIME continues to run

• $AC_OLD_PROG_NET_TIME is not changed

All system variables are reset to 0 as a result of POWER ON!

Note

Residual time for a workpiece

If the same workpieces are machined one after the other then using the following timer values

the remaining residual time for a workpiece can be determined.

• Processing time for the last workpiece produced (see $AC_OLD_PROG_NET_TIME)

• Current processing time (see $AC_ACT_PROG_NET_TIME)

The residual time is displayed on the user interface in addition to the current processing time.

Note

Using STOPRE

The system variables $AC_OLD_PROG_NET_TIME and $AC_OLD_PROG_NET_TIME_COUNT do

not generate any implicit preprocessing stop. This is uncritical when used in the part program if

the value of the system variables comes from the previous program run. However, if the trigger

for the runtime measurement ($AC_PROG_NET_TIME_TRIGGER) is written very frequently and

as a result $AC_OLD_PROG_NET_TIME changes very frequently, then an explicit STOPRE should

be used in the part program.

Timers that can be activated

Program runtime

The timers to measure the program runtimes are only available in AUTOMATIC mode.

System variable (channel-

Description

specific)

$AC_OPERATING_TIME

Total runtime of NC programs in Automatic mode (in s)

In the automatic mode, the runtimes of all programs between NC start and end of pro-

gram / reset are summed up.

The default is not to count in NC stop and override = 0%. Continued counting can be activated

at an override of 0% via MD27860.

The value is automatically reset to "0" every time the control powers up.

$AC_CYCLE_TIME

Runtime of the selected NC program (in seconds)

The runtime between NC Start and end of program / NC reset is measured in the selected NC

program.

The default is not to count in NC stop and override = 0%. Continued counting can be activated

at an override of 0% via MD27860.

The value is automatically reset to "0" every time a new NC program starts up. MD27860 can

be set to ensure that this value will be deleted even if there is a jump to the beginning of the

program with GOTOS or in the event of ASUBs and PROG_EVENTs starting.

$AC_CUTTING_TIME

Processing time in seconds

The runtime of the path axes (at least one is active) is measured in all NC programs between

NC Start and end of program / NC reset without rapid traverse active. MD27860 can be used

to set whether measuring should only be conducted when the tool is active or independent

of the tool state.

The measurement is interrupted when a dwell time is active.

The value is automatically reset to "0" every time the control powers up with default values.

Behavior of the timer that is always active

The behavior of the timer that is always active for GOTOS and override = 0% is set using machine

data:

MD27850 $MC_PROG_NET_TIMER_MODE

Bit

Value

Meaning

$AC_ACT_PROG_NET_TIME is not reset to "0" in case of a jump with GOTOS to the pro-

gram start (initial setting).

With a jump with GOTOS to the start of the program, $AC_ACT_PROG_NET_TIME is reset

to "0", the value is first saved in $AC_OLD_PROG_NET_TIME and the program counter

$AC_OLD_PROG_NET_TIME_COUNT is incremented.

$AC_ACT_PROG_NET_TIME is not increased for override = 0%. This means that the pro-

gram runtime is measured without the time for which the override was set to "0" (basic

setting).

$AC_ACT_PROG_NET_TIME is also increased for override = 0%. This means that the pro-

gram runtime is measured with the time for which the override was set to "0".

Behavior of the timer that can be activated

The behavior of the timer that can be activated for certain functions (e.g. test run feedrate,

program test) is set using machine data:

MD27860 $MC_PROCESSTIMER_MODE

Bit

Value

Meaning

No measurement during active dry run feedrate.

Measurement during active dry run feedrate.

No measurement during program test.

Only for bit 1 = 1 (timer for $AC_CYCLE_TIME is active)

$AC_CYCLE_TIME is reset to "0" also in case of Start through ASUB and PROG_EVENTs.

$AC_CYCLE_TIME is not reset to "0" in case of Start through ASUB and PROG_EVENTs.

Only for bit 2 = 1 (timer for $AC_CUTTING_TIME is active)

Timer for $AC_CUTTING_TIME counts only for the active tool.

Timer for $AC_CUTTING_TIME counts independent of the tool.

Examples

Example 1: Parameterization of the runtime measurement via MD27860

Activating the runtime measurement for the active NC program and hence no measurement in

case of active dry run feedrate and program test:

MD27860 $MC_PROCESSTIMER_MODE = 'H2'

Activating the measurement for the tool action time and measurement also with active dry run

feedrate and program test.

MD27860 $MC_PROCESSTIMER_MODE = 'H34'

Activating the measurement for the total runtime and the processing time with an active tool,

including measurement with a program test:

MD27860 $MC_PROCESSTIMER_MODE = 'H25'

Activating the measurement for the total runtime and the machining time (independent of the

tool), including measurement with a program test:

MD27860 $MC_PROCESSTIMER_MODE = 'Ha5'

Activating the measurement for the processing time with an active tool, including

measurements at an override = 0%, but not with a trial run feed active:

"Channel %1 workpiece target = %2 reached"

and of the channel-specific NC/PLC interface signal:

DB21, DBX317.1 (workpiece target reached)

$AC_TOTAL_PARTS

Total number of completed workpieces (actual workpiece total)

This counter specifies the total number of workpieces produced since the

start time. The value is only automatically reset to "0" when the control

runs up with default values.

$AC_ACTUAL_PARTS

Number of completed workpieces (actual workpiece total)

This counter registers the total number of workpieces produced since the

start time. On condition that $AC_REQUIRED_PARTS > 0, the counter is

automatically reset to "0" when the required number of workpieces

($AC_REQUIRED_PARTS) is reached.

$AC_SPECIAL_PARTS

Number of workpieces selected by the user

This counter supports user-specific workpiece counts. An alarm can be

defined to be output when the setpoint number of workpieces is reached

($AC_REQUIRED_PARTS). Users must reset the counter themselves.

Note

All workpiece counters are set to "0" when the control runs up with default values and can be

read and written independent of their activation.

Parameter assignment

Workpiece counting with user-defined M command

If the corresponding bit is set in MD27880, then the count pulse can be triggered via a user-

defined M command parameterized via the following machine data instead of via the end of

program M2/M30.

MD27882 $MC_PART_COUNTER_MCODE[<n>] (workpiece counting with user-defined M

command)

<n>

Meaning

MD27882[0] defines the M command in which $AC_TOTAL_PARTS is incremented.

MD27882[1] defines the M command in which $AC_ACTUAL_PARTS is incremented.

MD27882[2] defines the M command in which $AC_SPECIAL_PARTS is incremented.

The respective workpiece counter is incremented by "1", when a user-defined M command is

called.

Protection level for workpiece counting

Using the following machine data, the protection level for activating/deactivating the workpiece

counting at the user interface is set.

Program simulation

3.20.1

Function

The current part program is calculated completely in the program simulation and the result is

graphically displayed in the user interface. The result of programming is verified without

traversing the machine axes. Incorrectly programmed machining steps are detected at an early

stage and incorrect machining on the workpiece prevented.

3.20 Program simulation

Simulation NC

The simulation uses its own NC instance (simulation NC). Therefore, before a simulation is

started, the real NC must be aligned to the simulation NC. With this alignment, all active machine

data is read out of the NC and read into the simulation NC. The NC and cycle machine data is

included in the active machine data.

3.20.2

Program simulation in conjunction with compile cycles

Some compile cycles (CC) are supported in program simulation. The machine data of the

supported compile cycles is aligned once after the control has powered-up. An alignment with

"simulation start" does not take place!

Note

In part programs, CC-specific language commands and machine data of unsupported

CCs cannot be used (see also paragraph "CC-commands in the part program").

Special motion of supported CCs (OEM transformations) are - under certain circumstances -

incorrectly displayed.

CC-commands in the part program

Language commands in the part program of compile cycles that are not supported

(OMA1 ... OMA5, OEMIPO1/2, G810 ... G829, own procedures and functions) therefore result in

an alarm message and cancellation of the simulation without any individual handling.

Solution:

Individually handle the missing CC-specific language elements in the part program ($P_SIM

query).

Example:

Program code

Comment

N1 G01 X200 F500

IF (1==$P_SIM)

N5 X300

; CC not active for simulation.

4.1.1

Axes

Machine axes

Machine axes are the axes that actually exist on a machine tool.

Channel axes

Every geometry axis and every special axis is assigned to a channel and, therefore, a channel

axis. Geometry axes and additional axes are always traversed in "their" channel.

Geometry axes

The three geometry axes always make up a fictitious rectangular coordinate system, the basic

coordinate system (BCS).

By using FRAMES (offset, rotation, scaling, mirroring), it is possible to image geometry axes of

the workpiece coordinate system (WCS) on the BCS.

Special axes

In contrast to geometry axes, no geometrical relationship is defined between the special axes.

Path axes

Path axes are interpolated together (all the path axes of a channel have a common path

interpolator).

All the path axes of one channel have the same acceleration phase, constant travel phase and

delay phase.

Positioning axes

Positioning axes are interpolated separately (each positioning axis has its own axis interpolator).

Each positioning axis has its own feedrate and acceleration characteristic.

Synchronized axes

Synchronous axes are interpolated together with path axes (all path axes and synchronous axes

of one channel have a common path interpolator).

Basic functions

257

Axes, coordinate systems, frames

4.1 Brief description

All path axes and all synchronous axes of a channel have the same acceleration phase, constant

travel phase and deceleration phase.

Axis configuration

The machine data below are used to assign the geometry axes, special axes, channel axes and

machine axes as well as the names of the individual axis types:

MD20050 $MC_AXCONF_GEOAX_ASIGN_TAB (assignment of geometry axis to channel axis)

MD20060 $MC_AXCONF_GEOAX_NAME_TAB (name of the geometry axis in the channel)

MD20070 $MC_AXCONF_MACHAX_USED (machine axis number valid in channel)

MD20080 $MC_AXCONF_CHANAX_NAME_TAB (name of the channel axis in the channel)

MD10000 $MN_AXCONF_MACHAX_NAME_TAB (machine axis name)

MD35000 $MA_SPIND_ASSIGN_TO_MACHAX (assignment of spindle to machine axis)

Replaceable geometry axes

The "Replaceable geometry axes" function allows the geometry axes in a grouping to be replaced

by other channel axes.

Axes that are initially configured as synchronous special axes in a channel can replace any

selected geometry axis in response to a program command.

Link axis

Link axes are axes, which are physically connected to another NCU and whose position is

controlled from this NCU. Link axes can be assigned dynamically to channels of another NCU.

Link axes are not local axes from the perspective of a particular NCU.

The axis container concept is used for the dynamic modification of the assignment to an NCU.

Axis replacement with GET and RELEASE from the part program is not available for link axes

across NCU boundaries.

Further information

The link axes are described under Distributed systems (Page 815).

Axis container

An axis container is a circular buffer data structure, in which local axes and/or link axes are

assigned to channels. The entries in the circular buffer can be shifted cyclically.

In addition to the direct reference to local axes or link axes, the link axis configuration in the

logical machine axis image also allows references to axis containers.

This type of reference consists of:

• Axis container number

• A slot (circular buffer location within the corresponding container)

Coordinate systems

MCS

The machine coordinate system (MCS) has the following properties:

• It is defined by the machine axes.

• The machine axes can be perpendicular to each other to form Cartesian system or arranged

in any other way.

• The names of the machine axes can be defined.

• The machine axes can be linear or rotary axes.

BCS

The basic coordinates system (BCS) has the following properties:

• The geometry axes form a perpendicular Cartesian coordinate system.

• The BCS is derived from a kinematic transformation of the MCS.

BZS

The basic zero system (BZS) is the basic coordinate system with a basic offset.

SZS

The settable zero system (SZS) is the workpiece coordinate system with a programmable frame

from the viewpoint of the WCS. The workpiece zero is defined by the settable frames G54

to G599.

WCS

The workpiece coordinate system (WCS) has the following properties:

• In the workpiece coordinate system all the axes coordinates are programmed (parts

program).

• It is made up of geometry axes and special axes.

• Geometry axes always form a perpendicular Cartesian coordinate system

Axes, coordinate systems, frames

4.1 Brief description

• Special axes form a coordinate system without any geometrical relation between the special

axes.

• The names of the geometry axes and special axes can be defined.

• The workpiece coordinate system can be translated, rotated, scaled or mirrored with FRAMES

(TRANS, ROT, SCALE, MIRROR).

Multiple translations, rotational movements, etc., are also possible.

External work offset

The zero offset external has the following properties:

• At a time defined in the PLC, a predefined additional zero offset between the basic and the

workpiece coordinate systems is activated.

• The magnitudes of the offsets can be set by the following for each of the axes involved:

- PLC

- Operator panel

- Part program

• Activated offsets take effect at the instant the first motion block of the relevant axes is

processed after offset activation. The offsets are superimposed on the programmed path (no

interpolation).

The velocity, at which the zero offset external is applied, is as follows:

Programmed F value + 1/2 JOG velocity

The zero offset external is traversed at the end of G0 blocks.

• The activated offsets are retained after RESET and end of program.

• After POWER ON, the last active offset is still stored in the control but must be reactivated by

the PLC.

4.1.3

Frames

A frame is a closed calculation rule (algorithm) that translates one Cartesian coordinate system

into another.

Frame components

A frame consists of the following components:

Frame components

Coarse and fine offsets

As the assignment of machine axes to channel axes and, in particular, to geometry axes, can be

different in all channels, there is consequently no unique cross-channel geometric relationship

between the channel axes. Therefore, only offset, scaling and mirroring is possible for NCU-

global frames. Rotations are not possible.

G58: Absolute axis-specific programmable work offset (coarse offset)

The absolute component of the translatory offset (coarse offset) is programmed axis-specifically

with G58. The additive component of the translatory offset (fine offset) is retained.

G59: Additive axis-specific programmable work offset (fine offset)

The additive component of the translatory offset (fine offset) is programmed axis-specifically

with G59. The absolute component of the translatory offset (coarse offset) is retained.

G59 can only be used when the fine offset has been released:

• MD18600 $MN_MM_FRAME_FINE_TRANS = TRUE

• MD24000 $MC_FRAME_ADD_COMPONENTS = TRUE

Axes, coordinate systems, frames

4.1 Brief description

Rotation

Orientations in space are defined via frame rotations as follows:

• Rotation with ROT defines the individual rotations for all geometry axes.

• Solid angles with ROTS, AROTS, CROTS define the orientation of a plane in space.

• Frame rotation with TOFRAME defines a frame with a Z axis pointing in the tool direction.

Scaling

SCALE is used to program the programmable scale factors for all geometry axes and special axes.

If a new scaling is to be based on a previous scaling, rotation, translation or mirroring, then

ASCALE must be programmed.

Mirroring

The following machine data is used to set how the mirroring is to be performed:

MD10610 $MN_MIRROR_REF_AX

Concatenation

Frames and frame components can be combined using the concatenation operator ":". The

channel-specific active frame $P_ACTFRAME results, for example, from the chaining of all active

frames of the channel:

$P_ACTFRAME =

$P_PARTFRAME : $P_SETFRAME : $P_EXTFRAME :

$P_ISO1FRAME : $P_ISO2FRAME : $P_ISO3FRAME :

$P_ACTBFRAME : $P_IFRAME : $P_GFRAME :

$P_TOOLFRAME : $P_WPFRAME : $P_TRAFRAME :

$P_PFRAME : $P_ISO4FRAME : $P_CYCFRAME

Supplementary conditions

Incremental dimensioning G91

Incremental programming with G91 is defined such that the offset value is traversed additively

to the incrementally programmed value when a work offset is selected.

The behavior depends on the setting in the setting data:

SD42440 $SC_FRAME_OFFSET_INCR_PROG (work offsets in frames)

Value

Meaning

Work offset is applied on FRAME and incremental programming of an axis (= default setting).

Only the programmed path is traversed.

4.2.3

Channel axes

Meaning

Each geometry axis and each special axis is assigned to a channel. Geometry axes and additional

axes are always traversed in "their" channel.

4.2.4

Geometry axes

Meaning

The three geometry axes always make up a fictitious rectangular coordinate system.

By using FRAMES (offset, rotation, scaling, mirroring), it is possible to image geometry axes of

the workpiece coordinate system (WCS) on the BCS.

Application

Geometry axes are used to program the workpiece geometry (the contour).

Plane selection G17, G18 and G19 (DIN 66217) always refers to the three geometry axes. That

is why it is advantageous to name the three geometry axes X, Y and Z.

4.2.5

Special axes

Significance

In contrast to geometry axes, no geometrical relationship is defined between the special axes.

Note

Geometry axes have an exactly defined relationship in the form of a rightangled coordinate

system.

Special axes are part of the basic coordinate system (BCS). With FRAMES (translation, scaling,

mirroring), special axes of the workpiece coordinate system can be mapped on the basic

coordinate system.

Axes, coordinate systems, frames

4.2 Axes

Application

Typical special axes are:

• Rotary axes

• Machine tool axes

• Tool revolver axes

• Loader axes

4.2.6

Path axes

Meaning

Path axes are interpolated together (all the path axes of a channel have a common path

interpolator).

All the path axes of one channel have the same acceleration phase, constant travel phase and

delay phase.

The feedrate programmed under address F (path feedrate) applies to all the path axes

programmed in a block, with the following exceptions:

• An axis has been programmed that has been defined as having no control over the path

velocity with instruction FGROUP.

• Axes programmed with instructions POS or POSA have an individual feedrate setting (axis

interpolator).

Application

Path axes are used to machine the workpiece with the programmed contour.

4.2.7

Positioning axes

Meaning

Positioning axes are interpolated separately (each positioning axis has its own axis interpolator).

Each positioning axis has its own feedrate and acceleration characteristic. Positioning axes can

be programmed in addition to path axes (even in the same block). Path axis interpolation (path

interpolator) is not affected by the positioning axes. Path axes and the individual positioning

axes do not necessarily reach their block end points at the same time.

Basic functions

266

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

Axes, coordinate systems, frames

4.2 Axes

Instructions POS and POSA are used to program positioning axes and define block change

criteria:

• POS

Block change takes place when the path axes and positioning axes have reached their block

end points.

• POSA

Block change takes place when the path axes have reached their end of block position.

Positioning axes continue to traverse beyond block limits to their block end point.

Concurrent positioning axes differ from positioning axes in that they:

• Only receive their block end points from the PLC

• Can be started at any time (not at block limits)

• Do not affect the execution of current part programs.

Application

Typical positioning axes are:

• Loaders for moving workpieces away from machine

• Tool magazine/turret

4.2.8

Main axes

Meaning

A main axis is an axis that is interpolated by the main run.

This interpolation can be started as follows:

• From synchronized actions

(as command axes due to an event via block-related, modal or static synchronized actions)

• From the PLC via special function blocks in the basic PLC program

(named as a concurrent positioning axis or a PLC axis)

• Via the setting data or from the part program

(as an asynchronous or block-synchronous oscillating axis)

4.2 Axes

Channel control

An axis interpolated by the main axis reacts in terms of:

• NC stop

• Alarm handling

• Program control

• End of program

• RESET

Note

The response at the end of the program varies. The axis movement need not always be

completed and, therefore, may carry on beyond the end of the program.

Application

Certain axes in the main run can be decoupled at the channel response triggered by the NC

program sequence and controlled from the PLC. These axes are also interpolated in the main run

and respond independently for the channel and program sequence.

A PLC-controlled axis can then be controlled independently by the NC. This concerns the

following actions:

• The sequence for canceling the axis (equivalent to delete distancetogo)

• Stopping or interrupting the axis

• Continuing the axis (continue sequence of motion)

• Resetting the axis to its basic status

4.2.9

Synchronized axes

Meaning

Synchronous axes are components of the path axes, which are not referenced in order to

calculate the tool path velocity. They are interpolated together with path axes (all path axes and

synchronous axes of one channel have a common path interpolator).

All path axes and all synchronous axes of a channel have the same acceleration phase, constant

travel phase and deceleration phase.

The feedrate (path feedrate) programmed under address F applies to all the path axes

programmed in a block but not to the synchronous axes.

Synchronous axes take the same time to cover the programmed path as the path axes.

FGROUP command

The command FGROUP specifies whether the axis is a feed-defining path axis (used to calculate

the path velocity) or a synchronous axis (not used to calculate the path velocity).

N05 G00 G94 G90 M3 S1000 X0 Y0 Z0

; Axes X and Y are path axes,

Z is a synchronous axis

N20 G01 X100 Y100 F1000

; Progr. feedrate 1000 mm/min.

Feedrate of axis X = 707 mm/min.

Feedrate of axis Y = 707 mm/min.

N30 FGROUP (X)

; Axis X is a path axis,

axis Y is a synchronous axis

N20 X200 Y150

; Progr. Feedrate 1000 mm/min

Feedrate of Axis X = 1000 mm/min

Feedrate of Axis Y is set to 500 mm/min,

because only half the distance is to be

traversed.

Note

The channel axis name must be used for the FGROUP command.

This is defined by the machine data:

MD20080 $MC_AXCONF_CHANAX_NAME_TAB (name of the channel axis in the channel)

Application

In the case of helical interpolation FGROUP can be programmed to determine whether:

• The programmed feedrate should be valid on the path

(all three programmed axes are path axes)

• The programmed feedrate should be valid on the circle

(two axes are path axes and the infeed axis is a synchronous axis)

Drive assignment

Boundary conditions

• Leading zeros for user-defined axis names are ignored:

MD10000 `$MN_AXCONF_MACHAX_NAME_TAB[0] = X01 corresponds to X1

• The geometry axes must be assigned to the channel axes in ascending order without any

gaps.

• All channel axes that are not geometry axes are special axes.

Channel axis gaps

Normally, each channel axis defined in machine data MD20080

$MC_AXCONF_CHANAX_NAME_TAB must be assigned a machine axis via MD20070

$MC_AXCONF_MACHAX_USED.

In order to simplify commissioning series of machines with a different number of machine axes,

channel axes may also be defined, which are not assigned to any machine axis. As a result, gaps

can occur in the numbering sequence of the channel axes.

Any channel axis gaps must be explicitly enabled:

MD11640 $MN_ENABLE_CHAN_AX_GAP = 1

Without being enabled, a value of 0 in machine data MD20070 $MC_AXCONF_MACHAX_USED

stops the assignment of further channel axes to machine axes.

Example

Channel axis B is not assigned to a machine axis.

Axis configuration with channel axis gap (excerpt)

Boundary conditions

• Channel axes without assigned machine axes (channel axis gaps) are, regarding the number

and indexing of the channel axes, treated just like normal channel axes with associated

machine axes.

• If a channel axis without assigned machine axis (channel axis gap) is defined as geometry

axis, then this is rejected without an alarm.

4.2.11

Link axes

Meaning

A link axis is a machine axis that is not on the NCU from which it is traversed. The name of a local

machine axis is not entered in the machine data for the logical machine axis image of the

traversing NCU, but the NCU and machine axis name of the NCU to which it is physically

connected.

As an example, machine axis AX1 of NCU2 should be traversed from NCU1:

• NCU1: MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB[n] = NC2_AX1

Requirement

The NCUs involved must be connected using link communication as a requirement for using link

axes. The link axes and link communication functions are described in detail in Distributed

systems (Page 815).

Zero points and reference points

4.3.1

Reference points in working space

Zeros and reference points

The neutral position of the machine is obtained from the coordinate axes and the constructive

characteristics of the machine. The zero of the coordinate system is obtained by defining a

suitable reference point on the machine in its neutral position.

The position of the coordinate systems (MCS, BCS, BZS, SZS, WCS) is determined by means of

zeros.

Zero points

Reference points

M = Machine zero

R = Reference point

W = Workpiece zero

T = Toolholder reference point

Machine zero M

The machine zero M defines the machine coordinate system MCS. All other reference points refer

to the machine zero.

Workpiece zero W

The workpiece zero W defines the workpiece coordinate system in relation to the machine zero

M. The programmed part-program blocks are executed in the workpiece coordinate system WCS.

Reference point R

The position of the reference point R is defined by cam switches. Reference point R calibrates the

position measuring system.

With incremental encoders, the reference point must be approached every time the control

power is switched on. The control can only then work with the measuring system and transfer

all position values to the coordinate systems.

Toolholder reference point T

The toolholder reference point T is located on the toolholder locator. By entering the tool

lengths, the control calculates the distance between the tool tip (TCP Tool Center Position) and

the toolholder reference point.
