Measurement of an angle in an inclined plane in G17

With measurement type 17, two resulting angles α ₀ and α ₁ are determined for the skew of the

plane and entered in $AC_MEAS_RESULTS[0 ... 1]:

• $AC_MEAS_RESULTS[0] → Rotation around the abscissa

• $AC_MEAS_RESULTS[1] → Rotation around the ordinate

These angles are calculated with the three measuring points P1, P2 and P3.

With measurement type 17, the angle for the applicate ($AC_MEAS_RESULTS[2]) is always

preset with 0.

A set rotation that is entered in the result frame can be specified for the abscissa and/or the

ordinate. If only one angle is specified with a setpoint, the second angle is calculated so that the

three measuring points are on an inclined plane with the setpoint angle. Only rotations are

entered in the result frame, the WCS reference point is retained. The WCS is rotated so that Z' is

perpendicular to the inclined plane.

Figure 10-13

Redefining the WCS on the inclined plane in G17

Measurement of plane

The plane is measured in one measuring cycle. The cycle records the three measuring points and

passes the necessary values to the variable interface.

The MEASURE() function calculates the solid angles and translational offset of the new WCS' on

the basis of the input values.

628

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

Measurement

10.5 Workpiece and tool measurement

Transformation of measuring frame

The results of the calculation, i.e. the solid angles and translation, are entered in the

$AC_MEAS_FRAME measuring frame. The measuring frame is transformed according to the

selected frame in the frame chain. The solid angles are also stored in the

$AC_MEAS_RESULTS[0 ... 2] output values.

• $AC_MEAS_RESULTS[0]: Angle around the abscissa of the old WCS

• $AC_MEAS_RESULTS[1]: Angle around the ordinate

• $AC_MEAS_RESULTS[2]: Angle around the applicate

Specifying the new WCS' zero point

After performing the calculation, the measuring cycle can write and activate the selected frame

in the frame chain with the measuring frame. After activation, the new WCS' is positioned at

surface normal on the inclined plane, with measuring point P1 as the zero point of the new WCS'.

The programmed positions then refer to the inclined plane.

Application

CAD systems often define inclined planes by specifying three points P1, P2 and P3 on this plane.

Whereby, the 1st measuring point P1 is used as the new WCS' reference point, the 2nd

measuring point P2 specifies the direction of the abscissa X' of the new rotated WCS' coordinate

system and the 3rd measuring point P3 is required to determine the solid angles.

Measurement type 26: Backup of data management frames

Function

This measurement type offers the option of saving some or all data management frames with

their current value assignments to a file. The measurement can be initiated by executing a

command or via the part program. The function can also be activated from different channels.

The files are saved in the "_N_SYF_DIR" directory.

A Restore operation deletes the backed-up data and a new Save operation overwrites the

existing back-up.

The data saved last can be deleted from the data management through a new backup with the

following settings:

• $AC_MEAS_CHSFR = 0 ; System frames

• $AC_MEAS_NCBFR = 0 ; Global basic frames

• $AC_MEAS_CHBFR = 0 ; Channel basic frames

• $AC_MEAS_UIFR = 0 ; Number of settable frames

Note

If you decide to create a backup of all data management frames, remember that 1 KB of memory

is needed to save each frame. If insufficient memory is available, the process is aborted with an

error message.

Remedy: Adapt the configuration of the static user memory.

Measurement type 28: Specification of an additive rotation for taper turning

Function

Measuring type 28 can be used to specify an additive rotation through an angle α of the active

or a certain plane.

Value range: - 90 ° ≤ α ≤ + 90 °

The rotation takes place on the coordinate axis at right angles to the plane.

Figure 10-16

Specification of an additive rotation (α = +30°) for taper turning in the G17/G18/G19 plane

Application

With taper turning, the active plane is rotated by the taper angle, whereby the rotation is written

in the active cycle frame. The cycle frame is deleted with reset. Re-activation may be necessary.

The selection of the cycle frame is made depending on the SZS position display. If after activation

of the rotation, e.g. with active plane G18, traversing is performed in the direction of Z', the

actual positions of the corresponding axes change simultaneously for X and Z. Rotations with

active planes G17 and G19 behave similarly and are displayed in the above figure.

Preconditions

For simulated measuring, all of the machine axes in the system must be parameterized as

simulated axes:

Position-related switch request

Function

"Position-related switch request" is selected using the following NC-specific machine data:

• MD13230 $MN_MEAS_PROBE_SOURCE = 0

• MD13231 $MN_MEAS_PROBE_OFFSET = <position offset>

The axial switching position is calculated from the axial end position programmed in the

measuring block and the parameterized position offset:

Switching position[axis] = End position[axis] - position offset

During the measuring block, it is cyclically checked as to whether the switching position of the

axis is reached:

Setpoint position[axis] ≥ switching position[axis]

When the switching position is reached, the rising edge of the switching signal is generated for

probes 1 and 2. One position controller cycle later, the following edges.

Brief description

Contents

The PLC/NC interface comprises a data interface on one side and a function interface on the

other. The data interface contains status and control signals, auxiliary and G commands, while

the function interface is used to transfer jobs from the PLC to the NC.

This Description describes the functionality of interface signals, which are of general relevance

but are not included in the descriptions of functions.

Screen refresh behavior for overload

There are part programs, where the main run must wait until the preprocessing run provides

new blocks.

Preprocessing run and display refresh compete for NC processor time.

The following machine data can be used to set how the NC should behave if the preprocessing

run is too slow:

MD10131 $MN_SUPPRESS_SCREEN_REFRESH

Value

Meaning

0

If the preprocessing run of a channel is too slow, the display is not refreshed in all channels.

1

If the preprocessing run of a channel is too slow, the display is only refreshed in the time critical channels in order to

obtain processor time for the preprocessing run.

2

Display refresh is not suppressed.

The DEF... / REDEF... NC commands can be used to assign default settings to global user data

12.2.3

Read/write PLC variable

High-speed data channel

For high-speed exchange of information between the PLC and NC, a memory area is reserved in

the communications buffer on these modules (dual-port RAM). Variables of any type (I/O, DB,

DW, flags) may be exchanged within this memory area.

The PLC accesses this memory using 'Function Calls' (FC) while the NC uses system variables.

Organization of memory area

The user's programming engineer (NC and PLC) is responsible for organizing (structuring) this

memory area.

Every storage position in the memory can be addressed provided that the limit is selected

according to the appropriate data format (i.e. a DWORD for a 4-byte limit, a WORD for a 2-byte

limit, etc.).

The memory is accessed via the data type and the position offset within the memory area.

Access from NC

System variables are available in the NC for fast access to PLC variables from a part program or

synchronized action. The data is read/written directly by the NC. The data type results from the

identifier of the system variables. The position within the memory area is specified as index in

bytes.

Access from PLC

The PLC uses function calls (FC) to access the memory. The data is read and written immediately

in the DPR with the FC and not just at the beginning of the PLC cycle. Data type and position in

the memory area are transferred as parameters to the FC.

Communications buffer (DPR) for NC/PLC communication

Boundary conditions

• The structuring of the DPR memory area is the sole responsibility of the user. No checks are

made for matching configuration.

• A total of 4096 bytes are available in the input and output directions.

• Single-bit operations are not supported and must be linked back to byte operations by the

user.

• Since the contents of variables are manipulated directly in the communications buffer, the

user must remember that intermediate changes in values occur as a result of multiple access

operations where a variable is evaluated several times or when variables are linked (i.e. it may

be necessary to store values temporarily in local variables or R parameters or to set up a

semaphore).

• The user's programming engineer is responsible for coordinating access operations to the

communications buffer from different channels.

• Data consistency can be guaranteed only for access operations up to 16 bits (byte and word).

The user is solely responsible for ensuring consistent transmission of 32-bit variables (double

and real). A simple semaphore mechanism is available in the PLC for this purpose.

Access features

• Protection level 1 provides the greatest number of access rights, protection level 7 the least.

• If certain access rights are granted to a protection level, these protection rights automatically

apply to any higher protection levels.

• Conversely, protection rights for a certain protection level can only be altered from a higher

protection level.

• The access rights for protection levels 1 - 3 are defined by Siemens by default.

• Access rights can be set by querying the current keyswitch positions and comparing the

passwords entered. When a password is entered it overwrites the access rights of the

keyswitch position.

• Options can be protected on each protection level. However, option data can only be entered

in protection level 1.

• Access rights for protection levels 4 - 7 are merely suggested settings and can be altered by

the machine tool manufacturer or user.

- Lowercase characters

- Numbers

- Special characters (ASCII 0x20 to 0x7E)

• The character combination of a password must contain:

- At least one numeral

- At least one uppercase letter

- At least one lowercase letter

• A password must not be too similar to the following names:

- User names (manufacturer, service, user)

- Computer name

- The additional values that can be stored for a user in the Linux password file (so-called

GECOS data)

We recommend that you confine yourself to the characters available on the operator panel front

when selecting a password.

NOTICE

Default passwords must be changed

The default passwords of protection levels 1 - 3 must be changed to user-defined/individual

passwords at the latest before operational use.

NOTICE

SIEMENS cannot reset the passwords

SIEMENS has no way of resetting a password to the default password on a SINUMERIK.

Therefore, take good care of your modified passwords. The passwords can only be reset by

erasing the memory card and reinstalling a software version (restore -full). An update (restore

-update) does not reset the passwords to the default passwords.

NOTICE

Passwords are not included in the archive

Passwords are not included in the SINUMERIK archive. For this reason, they may have to be

Assigning secure passwords

Observe the following rules when assigning new passwords:

• When assigning new passwords, make sure that you do not assign passwords that can be

easily guessed, e.g. simple words, key combinations that can be easily guessed, etc.

• Passwords must always contain a combination of uppercase and lowercase letters as well as

numbers and special characters. Passwords must comprise at least eight characters. PINS

must comprise an arbitrary sequence of digits.

• Wherever possible and where it is supported by the IT systems, a password must always have

a character sequence as complex as possible.

Further rules for the assignment of secure passwords can be found at Federal Office for

Information Security (Bundesamt für Sicherheit in der Informationstechnik, abbreviated as BSI).

(https://www.bsi.bund.de/SharedDocs/Downloads/DE/BSI/Grundschutz/International/

GSK_15_EL_EN_Draft.pdf?__blob=publicationFile&v=2)

You can use a program for password management for assistance when dealing with passwords.

With its help, you can save passwords and PINs in encrypted form, manage them and generate

secure passwords.

Linux passwords

NC and Linux passwords are brought together on the SINUMERIK control system. The passwords

that apply in the NC for the access levels Manufacturer (OEM), Service and User are identical

to the passwords that apply in Linux for the corresponding Linux users manufact, service

and user. This means that if the NC password is changed via the HMI user interface, the

password of the Linux user is also changed. Conversely, a password change in Linux results in

simultaneous changing of the NC passwords.

The following equivalences apply:

Access level in the NC

Linux user

Manufacturer (OEM)

manufact

Service

service

User

user

After a software update, the passwords currently stored in the Linux system apply immediately

to the NC. The Linux passwords are the same as the default passwords that applied in the

delivered condition. If they were subsequently changed, these changed passwords apply to the

NC immediately after the software update.

disabled:

• Keyswitch position 0 represents the lowest access rights.

• Keyswitch position 3 represents the highest access rights.

Interface signals

The interface signals of keyswitch positions 1 to 3 can either be directly specified from the

keyswitch on the machine control panel or from the PLC user program.

DB10 DBX56.4 / .5 / .6 / .7 (switch positions 0 / 1 / 2 / 3)

It is only permissible to set one bit. If several bits are set simultaneously, the control internally

activates switch position 3.

Formatting interfaces

Formatting

The formatting interface is used to set which bits of the request and display interface are used

to address the motor data sets (MDS) and which are used to address the drive data sets (DDS):

DB31, ... DBX130.0 - 4, with bit x = <value>

<value>

Meaning

0

Bit position for motor data set (MDS) - or invalid bit position

1

Bit position for drive data set (DDS)

Motor and drive data sets in the drive

Formatting depends on the number of motor data sets (MDS) and drive data sets (DDS) in the

drive. The number can be determined using the following drive parameters:

• p0130 (number of motor data sets)

• p0180 (number drive data sets)

Validity of the interfaces

After powering up, as soon as the control has received all the required information from the drive

and this has been evaluated by the NC, the request (Page 688) and display interfaces

(Page 689) are shown as valid:

DB31, ... DBX130.7 == 1 (request and display interfaces valid)

If no or incompatible information is transferred from the drive, the request and display interfaces

are shown as invalid.

Note

With invalid request and display interfaces, it however remains the sole responsibility of the

user / machine manufacturer to perform a data set switchover via the invalid request and display

interfaces.
