Legal information Warning notice system

This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are graded according to the degree of danger.

DANGER

indicates that death or severe personal injury will result if proper precautions are not taken.

WARNING

indicates that death or severe personal injury may result if proper precautions are not taken.

CAUTION

with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.

CAUTION

Information on structure and contents

"Fundamentals" and "Advanced" Programming Manual

The description of the NC programming is divided into two manuals:

1. Fundamentals

This "Fundamentals" Programming Manual is intended for use by skilled machine operators with the appropriate expertise in drilling, milling and turning operations. Simple programming examples are used to explain the commands and statements which are also defined according to DIN 66025.

2. Job planning

The Programming Manual "Advanced" is intended for use by technicians with in-depth, comprehensive programming knowledge. By virtue of a special programming language, the SINUMERIK control enables the user to program complex workpiece programs (e.g. for free-form surfaces, channel coordination, ...) and makes programming of complicated operations easy for technologists.

Preface

1.1 Variables

1.1.1 General information about variables

The use of variables, especially in conjunction with arithmetic functions and check structures, enables part programs and cycles to be set up with extremely high levels of flexibility. For this purpose the system makes three different types of variable available.

• System variables

System variables are variables with a fixed predefined meaning; they are defined in the system and made available to the user. They are also read and written by the system software. Example: Machine data

The meaning of a system variable is, to a large extent, predefined by the system and its properties are fixed. However, minor modifications can be made to the properties by the user in the form of redefinition. See "Redefinition of system variables, user variables, and NC language commands (REDEF) [Page 31]".

• User variables

User variables are variables whose meaning is not known to the system; they are not evaluated by the system. The meaning is defined exclusively by the user.

User variables are subdivided into:

- Predefined user variables

Predefined user variables are variables which have already been defined in the system and whose number simply has to be parameterized by the user via specific machine data. The user can make significant changes to the properties of these variables. See "Redefinition of system variables, user variables, and NC language commands (REDEF) [Page 31]".

- User-defined variables

User-defined variables are variables which are defined exclusively by the user and are not created by the system until runtime. Their number, data type, visibility, and all other properties are defined exclusively by the user.

See "Definition of user variables (DEF) [Page 25]".

1.1.2 System variables

System variables are variables which are predefined in the system and provide access to the actual parameter settings associated with the control, as well as machine, control, and process statuses, in part programs and cycles.

Preprocessing variables

Preprocessing variables are system variables that are read and written in the context of preprocessing; in other words, at the point in time at which the part program block in which the system variable is programmed is interpreted. Preprocessing variables do not trigger preprocessing stops.

Main run variables

Main run variables are system variables which are read and written in the context of the main run; in other words at the point in time at which the part program block in which the system variable is programmed is executed. The following are main run variables:

• System variables which can be programmed in synchronized actions (read/write)

• System variables which can be programmed in the part program and trigger preprocessing stops (read/write)

• System variables which can be programmed in the part program and whose value is calculated during preprocessing but not written until the main run (main run synchronized: write only)

Prefix system

Flexible NC programming

1.1 Variables

In order that they can be specifically identified, the names of system variables are usually preceded by a prefix comprising the $ sign followed by one or two letters and an underscore.

$ + 1. Letter Significance: Data type System variables which are read/written during preprocessing $M

Machine data

Setting data, protection zones $T Tool management data $P Programmed values $C Cycle variables of ISO envelope cycles $O Option data R

R-parameters (arithmetic parameters) System variables which are read/written during the main run $$M

$$S

Machine data

Setting data $A Up-to-date main run data $V Servo data $R

When machine and setting data are used in the part program/cycle as preprocessing variables, the

R-parameters (arithmetic parameters)

prefix is written with one $ sign. When they are used in synchronized actions as main run variables, the prefix is written with two $ signs.

When an R-parameter is used in the part program/cycle as a preprocessing variable, the prefix is omitted, e.g. R10. When it is used in a synchronized action as a main run variable, a $ sign is written as a prefix, e.g. $R10.

General conditions

Exceptions in the prefix system

The following system of variables deviate from the prefix system specified above:

• $TC_...: Here, the 2nd letter C does not refer to channel-specific system variables but to toolholder-specific system variables (TC= tool carrier).

• $P_ ...: Channel-specific system variables

Flexible NC programming

1.1 Variables

Use of machine and setting data in synchronized actions

When machine and setting data are used in synchronized actions, the prefix can be used to define whether the machine or setting data will be read/written synchronous to the preprocessing run or the main run.

If the data remains unchanged during machining, it can be read synchronous to the preprocessing run. For this purpose, the machine or setting data prefix is written with a $ sign:

Program code

ID=1 WHENEVER G710 $AA_IM[z] < $SA_OSCILL_REVERSE_POS2[Z]–6 DO $AA_OVR[X]=0

If the data changes during machining, it must be read/written synchronous to the main run. For this purpose, the machine or setting data prefix is written with two $ signs:

Program code

ID=1 WHENEVER $AA_IM[z] < $$SA_OSCILL_REVERSE_POS2[Z]–6 DO $AA_OVR[X]=0

Note Writing machine data

When writing an item of machine or setting data, it is important to ensure that the access level which is active when the part program/cycle is executed permits write access and that the data is set to take "IMMEDIATE" effect.

1.1.3 Predefined user variables: Arithmetic parameters (R)

Function

Arithmetic parameters or R-parameters are predefined user variables with the designation R, defined as an array of the REAL data type. For historical reasons, notation both with array

index, e.g. R[10], and without array index, e.g. R10, is permitted for R-parameters.

When using synchronized actions, the $ sign must be included as a prefix, e.g. $R10.

When used as a preprocessing variable:

R<n> R[<expression>]

1.1.4 Predefined user variables: Link variables

Function

Link variables can be used in the context of the "NCU-Link" function for cyclic data exchange between NCUs which are linked on a network. They facilitate data-format-specific access to the link variables memory. The link variables memory is defined both in terms of size and data structure on a system-specific basis by the user/machine manufacturer.

Link variables are system-global user variables which can be read and written in part programs and cycles by all NCUs involved in a link if link communication has been configured. Unlike global user variables (GUD), link variables can also be used in synchronized actions.

On systems without an active NCU link, link variables can be used locally on the control as additional global user variables alongside global user variables (GUD).

• MAX_INDEX is calculated from the parameterized size of the link variables memory: MAX_INDEX = (MD18700 $MN_MM_SIZEOF_LINKVAR_DATA) - 1

• Only indices may be programmed, so that the bytes addressed in the link variables memory are located on a data format limit ⇒ Index = n * bytes, where n = 0, 1, 2, etc.

– $A_DLB[i]: i = 0, 1, 2, etc. – $A_DLW[i]: i = 0, 2, 4, etc. – $A_DLD[i]: i = 0, 4, 8, etc. – $A_DLR[i]: i = 0, 8, 16, etc.

Example

An automation system contains 2 NCUs (NCU1 and NCU2). Machine axis AX2 is connected to NCU1. It is traversed as a link axis of NCU2.

NCU1 writes the actual current value ($VA_CURR) of axis AX2 cyclically to the link variables memory. NCU2 reads the actual current value transmitted via link communication cyclically and displays alarm 61000 if the limit value is exceeded.

The data structure in the link variables memory is illustrated in the following figure. The actual current value is transmitted in the REAL value.

1.1.5 Definition of user variables (DEF)

Function

Flexible NC programming

1.1 Variables

The DEF command is used to define user-specific variables and assign values to them. To set them apart from system variables, these are called user-defined variables or user variables

(user data).

According to range of validity (in other words, the range in which the variable is visible) there are the following categories of user variable:

• Local user variables (LUD)

Local user variables (LUD) are variables defined in a part program which is not the main program at the time of execution. They are created when the part program is called and deleted at the end of the part program or when the NC is reset. Local user variables can only be accessed within the part program in which they are defined.

• Program-global user variables (PUD)

Program-global user variables (PUD) are user variables defined in a part program used as the main program. They are created when the part program starts up and deleted at the end of the part program or when the NC is reset. It is possible to access PUD in the main program and in all subprograms of the main program.

• Global user variables (GUD)

Global user variables (GUD) are NC- or channel-global variables which are defined in a data block (SGUD, MGUD, UGUD, GUD4 to GUD9) and are retained following shutdown and restart. GUD can be accessed in all part programs.

Job planning Programming Manual, 02/2011, 6FC5398-2BP40-1BA0

Flexible NC programming

1.1 Variables

User variables must be defined before they can be used (read/write). The following rules must be observed in this context:

• GUD have to be defined in a definition file, e.g. _N_DEF_DIR/_M_SGUD_DEF.

• PUD and LUD have to be defined in a definition section of the part program.

• The data must be defined in a dedicated block.

• Only one data type may be used for each data definition.

• A number of variables of the same data type can be defined for each data definition.

Program-global user variables (PUD)

NOTICE Visibility of program-local user variables (PUD) Program-local user variables (PUD) defined in the main program will only be visible in

subprograms if the following machine data is set:

MD11120$MN_LUD_EXTENDED_SCOPE = 1

If MD11120 = 0 the program-local user variables defined in the main program will only be visible in the main program.

Cross-channel use of an NCK-global user variable of the AXIS data type

An NCK-global user variable of the AXIS data type initialized during definition in the data block with an axis identifier can then only be used in other NC channels if the axis has the

same channel axis number in these channels.
