Safety Guidelines

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

without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.

Notice

indicates that an unintended result or situation can occur if the corresponding information is not taken into account.

If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage.

1.1Variables and arithmetic parameters (user-defined variables, arithmetic parameters, system variables)

Function

Using variables in place of constant values makes a program more flexible. You can respond to signals such as measured values or, by storing setpoints in the variables, you can use the same program for different geometries.

With variable calculation and jump instructions a skilled programmer is able to create a very flexible program archive and save a lot of programming work.

Variable types

The control uses 3 classes of variable:

User-defined variables	Name and type of variable defined by the user, e.g., arithmetic
	parameter.
Arithmetic variables	Special, predefined arithmetic variable whose address is R plus a
	number. The predefined arithmetic variables are of the REAL type.
System variables	Variable provided by the control that can be processed in the
	program (write, read). System variables provide access to zero
	offsets, tool offsets, actual values, measured values on the axes,
	control states, etc.
	(See Appendix for the meaning of the system variables).

Variable types

Type	Meaning	Value range
INT	Integers with leading sign	±(231 - 1)
REAL	Real numbers (fractions with decimal	±(10-300 … 10+300)
	point, LONG REAL in acc. with IEEE)

Programming Manual, 11/2006, 6FC5398-2BP10-2BA0

Flexible NC programming

1.1 Variables and arithmetic parameters (user-defined variables,arithmetic parameters, system variables)

BOOL	Boolean values: TRUE (1) and	1.0
	FALSE (0)
CHAR	ASCII character specified by the	0 … 255
	code
STRING	Character string, number of	Sequence of values with 0 ... 255
	characters in [...], maximum of
	200 characters
AXIS	Axis identifiers only (axis addresses)	Any axis identifiers in the channel
FRAME	Geometric data for translation,
	rotation, scaling, mirroring, see the
	"Frames" Chapter

Arithmetic variables

Address R provides 100 arithmetic variables of type REAL by default.

The exact number of arithmetic variables (up to 32535) is defined in machine data.

Example: R10=5

System variables

The control provides system variables that can be contained and processed in all running programs.

System variables provide machine and control states. Some system variables cannot be assigned values.

Summary of system variables

Special identifiers of system variables always begin with a "$" sign. The specific names then follow.

1st letter	Meaning
$M	Machine data
$S	Setting data
$T	Tool management data
$P	Programmed values
$A	Current values
$V	Service data
2nd letter	Meaning
N	NCK global
C	Channel-specific
A	Axis-specific

Example: $AA_IM

Meaning: Current axis-specific value in the machine coordinate system.

1.2Variable definition (DEF user-defined variables LUD, GUD, PUD)

Function

In addition to the predefined variables, programmers can define and initialize their own variables.

Local variables (LUD) are only valid in the program where they are defined. Global variables (GUD) are valid in all programs.

Machine data are used to redefine the local user variables (LUD) defined in the main program as program-global user variables (PUD).

1.2 Variable definition (DEF user-defined variables LUD, GUD, PUD)

Note

If a variable is not assigned a value on definition, the system sets zero as the default.

Variables must be defined at the beginning of the program before they are used. The definition must be made in a separate block; only one variable type can be defined per block.

Parameter

INT	Variable type integer, i.e., whole number
REAL	Variable type real, i.e., factional number with decimal point
BOOL	Variable type Boolean, i.e., 1 or 0 (TRUE or FALSE)
CHAR	Variable type char, i.e., ASCII-coded character
	(0 to 255)
STRING	Variable type string, i.e., character string
AXIS	Variable type axis, i.e., axis addresses and spindles
FRAME	Variable type frame, i.e., geometric data

Example:

Variable type	Description
INT
DEF INT NUMBER	This creates a variable of type integer with the
	name NUMBER.
	System initializes with zero.
DEF INT NUMBER=7	This creates a variable of type integer with the
	name NUMBER. The system initializes the
	variable with 7.
REAL
DEF REAL DEPTH	This creates a variable of type real with the name
	DEPTH.
	System initializes with zero (0.0).
DEF REAL DEPTH=6.25	This creates a variable of type real with the name
	DEPTH. The variable is initialized with 6.25.
DEF REAL DEPTH=3.1,LENGTH=2,NUMBER	More than one variable can be defined in a line.
BOOL
DEF BOOL IF_TOO_MUCH	This creates a variable of type BOOL with the
	name IF_TOO_MUCH.
	System initializes with zero (FALSE).
DEF BOOL IF_TOO_MUCH=1 or	This creates a variable of type BOOL with the
DEF BOOL IF_TOO_MUCH=TRUE or	name IF_TOO_MUCH.
DEF BOOL IF_TOO_MUCH=FALSE
CHAR

Flexible NC programming 1.2 Variable definition (DEF user-defined variables LUD, GUD, PUD)

DEF CHAR GUSTAV_1=65	A code value for the corresponding ASCII
	character or the ASCII character itself
DEF CHAR GUSTAV_1="A"	can be assigned to a variable of type CHAR
	(code value 65 corresponds to letter "A").
STRING
DEF STRING[6] MUSTER_1="BEGIN"	Variables of type string can contain a string
	(sequence of characters). The maximum number
	of characters is enclosed in square brackets after
	the variable type.
AXIS
DEF AXIS AXIS_NAME=(X1)	Variables of type AXIS have the name
	AXIS_NAME and are assigned the axis identifier
	of a channel - X1 in this case.
	(Axis names with an extended address must be
	enclosed in parentheses.)
FRAME
DEF FRAME BEVEL_1	Variables of type FRAME have names like
	BEVEL_1.

Note

A variable of type AXIS can contain an axis identifier and a spindle identifier of a channel.

Note

Axis names with an extended address must be enclosed in parentheses.

Example Redefine local (LUD) and program-global user variables (PUD)

If they are defined in the main program, they will also be valid at all levels of the subprograms called. They are created with part-program start and deleted with part-program end or RESET.

If machine data $MN_LUD_EXTENDED_SCOPE is set, it is not possible to define a variable with the same name in the main and subprograms.

	$MN_LUD_EXTENDED_SCOPE=1	;Main program
	PROC MAIN
	DEF INT VAR1	;PUD definition

1.3Array definitions (DEF, SET, REP)

Function

An array is a memory area defined using the variable type with name and size. Arrays with up to two dimensions can be defined.

Note

Maximum array size

When defining arrays, the maximum array size of the 1st and 2nd dimension is 32767 for the array index [n, m].

Initialization of arrays

Initialization values can be assigned to the array elements:

•during the program execution

or

•already with the array definition.

In 2-dimensional arrays, the right array index is incremented first.

• Initialization with value lists; SET Array definition options

DEF Type VARIABLE = SET(VALUE)

DEF Type ARRAY[n,m] = SET(VALUE, value, …) or

DEF Type VARIABLE = Value

DEF Type ARRAY[n,m] = (value, value, …)

Note

SET is optional in the array definition.

Initializing during the program run

ARRAY[n,m]= SET(value, value, value,…)

ARRAY[n,m]= SET(expression, expression, expression,…)

• Initialization with the same values, REP Array definition options

When "Array" variables are created,

DEF Type ARRAY[n,m] = REP(value) initializes all elements. With

DEF Type ARRAY[n,m] = REP(value, no.arrayElements), only the number of array elements defined in "No.arrayElements" is initialized with "Value".

Initialization begins at array index 0. The remaining variable elements are initialized with zero. If "No.arrayElements" = 0, the entire variable array is initialized with zero, as, for example, for all 30 array elements of varName:

DEF REAL varName[30] =REP(3.5, 0)

Note

Variables of type FRAME cannot be initialized.

If a value smaller than zero or larger than the number of array elements is programmed as the range, a "Value range exceeded" alarm is output.

Initializing during the program run

ARRAY[n,m] = REP(value) ARRAY[n,m] = REP(expression)

ARRAY[n,m] = REP(value, no.arrayElements) ARRAY[n,m] = REP(expression, no.arrayElements)

If the range definition "No.arrayElements" = 0, the current values of all array variables remain unchanged, e.g.:

varName [12] =REP(44.5, 0)

Note

Variables of type FRAME are permissible and can be initialized very simply in this way.

Initialization with value lists for the array definition, SET

•As many array elements are assigned as initialization values are programmed.

•Array elements without values (gaps in the value list) are automatically initialized to 0.

•For variables of type AXIS, gaps in the value list are not permitted.

•Programming more values than exist in the remaining array elements triggers an alarm. Example

DEF REAL ARRAY[2,3]=(10, 20, 30, 40)

Initialization with value lists in the program execution, SET

•Initialization is the same as in array definition.

•Expressions are possible values in this case too.

•Initialization starts at the programmed array indexes. Values can also be assigned selectively to subarrays.

Example: Assignment of expressions

ARRAY[0,0] = SET(1, 2, 3, 4, 5)

The axis index of axis variables is not traversed: Example: Initialization in one line

$MA_AX_VELO_LIMIT[1, AX1] = SET(1.1, 2.2, 3.3)

Initialization with the same values for the array definition, REP

All array elements are assigned the same value (constant). Variables of type FRAME cannot be initialized. Examples:

DEF REAL ARRAY5[10,3] = REP(9.9)

Initialize the variable-array ranges varName[0] to varName[3] with 3.5:

DEF REAL varName[30] =REP(3.5, 4)

Set array variable to a programmed value range by range:

varName[5] = REP(4.5, 10) ;Set varName[5] to varName[14] to value 4. Set R parameters to certain values range by range:

R10 = REP(2.4, 15) ;Set R10 to R24 to value 2.4.

Initialization with the same values in the program execution

•Expressions are possible values in this case too.

•All array elements are initialized to the same value.

•Initialization starts at the programmed array indexes. Values can also be assigned selectively to subarrays.

Example: Initialization of all elements with one value

DEF FRAME FRM[10]

FRM[5] = REP(CTRANS (X,5))

1.4Indirect programming

Function

Indirect programming permits general-purpose use of programs. The extended address (index) is substituted by a variable of suitable type.

Indirect G code programming

Indirect programming of G codes using variables facilitates effective cycle programming. Two parameters

G code groups with integer constants

G code numbers with integer/real type variables are available for this purpose.

Programming

ADDRESS[INDEX] or

G[<group_index>] = <integer/real_variable>

Indirect programming of G codes using variables for effective cycle programming

Parameters

All addresses are parameterizable except:

•N - block number

•L - subroutine

Indirect programming is not possible for settable addresses.

Example: X[1] in place of X1 is not permissible.

ADDRESS [INDEX] G<group_index

<Integer/real_variable>

Address with parameter details as index Index variable, e.g., spindle no., axis ....

G code groups: Integer constants with which the G code group is selected.

G code numbers: Variable of the integer or real type with which the G code number is selected

Valid G code groups

Only modal G code groups can be programmed indirectly. Non-modal G code groups are rejected with alarm 12470. Valid G code numbers

Arithmetic functions are not permissible in indirect G code programming.

The G code number must be stored in a variable of type integer or real. Invalid G code numbers are rejected with alarm 12475.

Flexible NC programming 1.4 Indirect programming

If it is necessary to calculate the G code number, this must be done in a separate parts program line before the indirect G code programming.

Note

All the valid G codes are shown in the PG, in the "List of G functions/preparatory functions" section in various groups. See /PG/ Programming Guide Fundamentals, "Tables"
