GENERAL
INTRODUCTION
ASSET (Advanced Super Set Extension Tool) is a programming language that enhances
10 Series standard programming capabilities. It provides a set of instructions, variables and
variables handling rules that facilitate customisation of 10 Series functions.
In particular, ASSET permits to:
• create personalised video screens.
• create data entry windows and personalise their size, position, graphic layout, background and
foreground colors, and the number and length of the various data entry fields.
• open, read, write and close ASCII files.
• manage PLUS tables and read and/or write accessible parameters.
• read and/or write PLUS I/O variables.
• handle a series of process commands used for reading the process status, the axes position,
the tool parameters, etc.
• handle the serial line from part programs.
• send out operating commands in emulation of the Front Panel/Teach Pendant.
These operations can be carried out by means of specific 3-letter ASSET codes or by writing in the
program blocks the ASSET variables that provide access to parameters that are normally
inaccessible to the programming environment. These commands can be given by the part program
or entered from keyboard, i.e. written by the operator when the system is in MDI mode.
For example, ASSET can be used for programming a machining operation that needs to be
automatically interrupted and kept on hold by the system until the operator fills in a given data entry
window. Each ASSET command described in the manual is supplied with application examples.
10 Series CNC ASSET Reference Manual (06) 1-1
Chapter 1
General
Like all high level languages, ASSET must also be used by adequately trained personnel that are
also well acquainted with the characteristics of the system. If inappropriate alterations are made to
the system and logic parameters accessible via ASSET, serious system errors and malfunctions
may occur.
ASSET instructions can be easily combined with the traditional 10 Series programming language.
Actually, ASSET enhances 10 Series programming capabilities by making it possible for 10 Series
commands to handle ASSET variables.
In addition to standard commands, functions and variables, ASSET uses 10 Series syntactic rules
and conventions. For more information about these programming rules and conventions, please
refer to 10 Series CNC Programming Manual.
1-2 10 Series CNC ASSET Reference Manual (06)
Chapter 1
General
VARIABLES
ASSET permits to write, read and alter any system variable, with the exception of those to which
special restrictions apply. In doing so it applies the same syntactic rules and conventions as the
standard 10 Series programming language. For more information about standard programming,
please refer to Chapter 7 of 10 Series Programming Manual.
Here is a list of variables handled by ASSET:
• Local variables: E and H.
• System variables: SN and SC.
• User variables: They are identified by an exclamation mark followed by a name. For example,
!USER1. They can contain long real numerical formats and alphanumeric characters.
• PLUS variables: They are identified by an @ followed by a name. For example, @PROG They
can contain short, long or boolean numerical values.
• User Table variables: They are identified by an L followed by a numerical index from 0 through
399 which indicates the table cell. The index-cell relationship will be discussed in a later
chapter.
• PLUS Table variables: They are identified by the $ character followed by the name given to the
variable in the table and an index enclosed between brackets which provides the axes ID (axes
table), the record number (tools table) or the tool offset number (tool offsets table).
Examples:
$AXORIG(2) Identifies the current origin of the axis whose ID is 2 (read only)
$TSTATUS(25) Identifies the condition of the tool stored in record 25 of the tools table
$TACTL1(125) Identifies the current length of the tool stored in record 125 of the tools offset
table.
User Table and PLUS variables are described later in this chapter. For more information about
local, system user variables, please refer to the following 10 Series documents: Programming
Manual, Characterisation Manual, and PLUS Library Manual.
10 Series CNC ASSET Reference Manual (06) 1-3
Chapter 1
General
User Table Variables
The User Table (refer to Chapter 3 in the "PLUS Application Manual") has 100 records, each one
of which is made up of 4 variables, for a total 400 variables. The variable index ranges from 0 to
399.
The records and the variables stored in them are arranged sequentially, as shown in the following
table:
Record N° Variable 1 Variable 2 Variable 3 Variable 4
000001 L0 L1 L2 L3
000002 L4 L5 L6 L7
000003 L8 L9 L10 L11
000004 L12 L13 L14 L15
...............
...............
000099 L392 L393 L394 L395
000100 L396 L397 L398 L399
To calculate the index when the position of the cell in the table and the variable are known, the
following formula can be used:
Index = (Record Number - 1) x 4 + (Number of the variable in the record - 1)
For example, the index of the highlighted cell in the table is as follows:
Index = (4 - 1) x 4 + (3 - 1) = 14
To calculate the record number and the variable when the index is known, the following formula
may be used:
Record = (Index / 4) + 1
Variable = [Remainder of (Index / 4)] + 1
For example, L145 addresses record 37 (145 / 4 + 1) and variable 2 (remainder of the division + 1
= 1 + 1).
1-4 10 Series CNC ASSET Reference Manual (06)
Chapter 1
General
PLUS Tables Variables
PLUS Tables include the Axes Tables, the Tools Tables and the Tools Offsets Tables. The
contents of these tables are normally handled by the machine logic. Each PLUS Table is made up
of a given number of pages which contain the parameters that describe the object of the table. The
number of pages in each table is as follows:
Table N° of Pages Contents
Axes table 32 Axes identification
Tools Table 250 Record number in the table
Tool OffsetsTable 300 Tool offsets number
The table page number coincides with the index that follows the variable name.
The type, number and symbol of a parameter vary from table to table. The sections that follow
illustrate a typical page of each table. For further information about these tables, refer to Chapter 3
of the "PLUS Application Manual".
The ASSET instruction LCK permits to write protect PLUS tables. When write protection is active,
PLUS tables may be accessed only via ASSET. More information about the LCK triliteral is
provided in the final section of this chapter.
Values read or written in PLUS tables using ASSET are not affected by the
current unit of measure (G70/G71) but are considered as absolute values. It
should be remembered therefore that any numeric values representing
lengths are with reference to the machine's unit of measure configured in
AMP; it is up to the operator to perform any conversion required.

General
PLUS I/O
PLUS inputs are arranged in 85 11-bit arrays followed by 427 16-bit arrays; outputs are arranged in
85 6-bit arrays followed by 427 16-bit arrays. Accordingly, a total of 7767 inputs and 7342 outputs
has to be managed.
An array and its Input or Output are identified by an I or an O preceded by $ and followed by the bit
index between brackets: $I(index) or $O(index), as in the User Table. For example, $I(35),
$O(812).
The Input/Output arrays can be pictured as tables, as shown in the figures below.
Inputs (the first 85 arrays)
Arrays or groups of inputs may be numbered from 00 to 84, whereas the 11 bits in the array are
numbered from 0 to 10. The index of the first input variable will be 0, whereas the index of the last
input variable will be 934, as shown in the table below:
Array bit 0 bit 1 bit 2 bit 3 bit 4 bit 5 bit 6 bit 7 bit 8 bit 9 bit 10

To calculate the index from the cell position, i.e. when the array and bit numbers are known, use
this formula:
Index = array number x 11 + bit number
For example, to address bit 7 from array 03, the $I variable must be assigned the following index:
Index = 3 x 11 + 7 = 40
The resulting variable will be $I(40), as shown in the table.
To calculate the array and bit numbers from the index, divide the index by 11: the ---- will be the
array number and the remainder will indicate the bit number.
For example, the $I(172) variable will address the 15 (172 / 11) array and the 7 (172 - 15 x 11) bit.

Chapter 1
General
Inputs (after the 85th array)
The numbering of the individual input arrays or input groups goes from 85 to 511; the 16 bits within
an array are numbered from 0 to 15. In these conditions the index of the first input variable will be
935, the index of the last variable will be 7766, as can be seen from the table below:
Array bit 0 bit 1 bit2bit3bit4bit5bit6bit7bit8bit9bit10bit11bit12bit13bit14bit 15

$I(7735) $I(7736) $I(7750)
$I(7751) $I(7752) $I(7766)
The formula used to define an index starting from the position of the cell (i.e., the array number and
the bit number), is as follows:
index = (array number – 85) X 16 + 935 + bit number
For example, if we want to address bit 13 in array 86 (i.e., the grey-coloured cell), the index of
variable $I must be determined as follows:
Index = (86 – 85) X 16 + 935 +13 = 964
In this case, the variable will therefore turn out to be $I(964), as shown in the table. Conversely, if
we want to determine an array and a bit, knowing the relative index, we must subtract 935 from the
index and then divide the value obtained by 16. By adding 85 to the whole number determined in
this manner, we get the array number, while the difference will identify the bit within the array. For
example: for variable $I (7736) we get array 510 ((7736-935)/16+85) and bit 1 ((7736-935) / 16).

Outputs (the first 85 arrays)
Arrays or groups of outputs may be numbered from 00 to 84, whereas the 6 bits in the array are
numbered from 0 to 5. The index of the first output variable will be 0, whereas the index of the last
output variable will be 509, as shown in the table below:
Array bit 0 bit 1 bit 2 bit 3 bit 4 bit 5

84 $O(504) $O(505) $O(506) $O(507) $O(508) $O(509)
To calculate the index from the cell position, i.e. when the array and bit numbers are known, use
this formula:
Index = array number x 6 + bit number
Examples:
1. To address bit 2 from array 03, the $O variable must be assigned the following index:
Index = 3 x 6 + 2 = 20
The resulting variable will be $O(20), as shown in the table.
2. To calculate the array and bit numbers from the index, divide the index by 16: the integer value
obtained through the division will be the array number and the remainder will indicate the bit
number.
For example, the $O(214) variable will address the 35 (214/6) array and the 4 (214 - 35 x 6) bit.

$O(7326) $O(7327) $0(7341)
The formula used to define an index starting from the position of the cell (i.e., the array number and
the bit number), is as follows:
index = (array number – 85) X 16 + 510 + bit number
For example, if we want to address bit 7 in array 86 (i.e., the grey-coloured cell), variable $O must
be assigned the following index:
Index = (86 – 85) X 16 + 510 + 7 = 533
In this case, the variable will therefore turn out to be $O(533), as shown in the table. Conversely, if
we want to determine an array and a bit, knowing the relative index, we must subtract 510 from the
index and then divide the value obtained by 16. By adding 85 to the whole number determined in
this manner, we get the array number, while the difference will identify the bit within the array. For
example: for variable $O (680) we get array 95 ((680-510)/16+85) and bit 10 ((680-510) / 16).

FILE
10 Series ASSET can manage two types of files:
• ASCII files
• Binary (data) files
Except where otherwise stated, these files are located in default directory E:\FILE or F:\FILE, which
ASSET can access. However it is also possible to read or write with ASSET in files belonging to
other directories. In this case, the full pathname and extension of the file in question must be
specified (e.g. E:\USER\FILE|FILE1.DAT).
These files are located in the E:\FILE or F:\FILE directories, which are accessible to ASSET. Their
main characteristics are discussed in the sections that follow.
ASCII files
ASCII files may contain part programs, messages, etc. They are not formatted and have records of
undefined length that must be written and read sequentially. ASCII files are given the .ASC
extension by the system by default, in cases where the file was opened in read or write mode
without the full pathname and extension being specified.
In an ASCII file it is not possible to read, write or search for a specific record. Maximum record
length is 127 characters.
The system always starts reading an ASCII file from the first record, on which it positions
automatically as it opens the file.
Writing an ASCII file means adding a new record after the last record in the file. To edit an ASCII
file it is necessary to read it sequentially, make the necessary alterations and write a new file that
will replace the old one.

General
Binary files
Binary files are formatted files that are used for storing the parameters managed by the system, i.e.
variables, numbers, parameters, etc. Records have a fixed length that is declared when the first
record is written. Binary files are given the .DAT extension by the system by default, in cases
where the file was opened in read or write mode without the full pathname and extension being
specified.
For example, to write into a file the tool code with the relevant TUSER1-4 user variables the binary
file record will be as follows:
TCODE TUSER1 TUSER2 TUSER3 TUSER4
When the system writes the first record it automatically creates a header that is invisible to the user
and defines the format of all the file records.
Binary file records can be searched for and addressed for reading and writing operations.
A record can be up to 300 bytes long.
To calculate the record length in bytes it is necessary to know the length of each of the variables
stored in the record. This information is listed in the table below:
Variable Length in bytes
Boolean 1
Byte 1
Short 2
Long 4
Real 4
Long Real (Double) 8
String Number of characters in the string.
For example: SC0.4 --> 4 characters --> 4 bytes
Example:
if you write the following variables into a table:
(WRT,1,E1,E5,L3)
The record will occupy 24 bytes because there are 3 double variables and 3 x 8 = 24
For the following writing command:
(WRT,1,SC0.60,L5,"TEST")
the record length will be 72 bytes (60 + 8 + 4).
Unless otherwise specified in the reading or writing command, access to the file occurs at the first
record for reading and after the last record for writing. After a record has been read or written the
cursor will position to the subsequent record.
When reading or writing commands including ASSET binary files it is possible to declare a
parameter that specifies the number of the target record.

COMMANDS
ASSET ensures full compatibility with the commands and instructions typical of the standard
programming environment. For more information about parametric programming, please refer to
Chapter 7 of the 10 Series Programming Manual.
Here is a list of syntactic and typographical conventions used throughout the manual:
The function name and the mandatory signs will be printed in boldface type. Mandatory parameters
associated to a function will be indicated by an italicised mnemonics. Parameters may be enclosed
between brackets.
[ ] Square brackets enclose optional parameters that may be omitted. Do not write these
brackets into the block.
{ } Graphs enclose parameters that are alternative to one another and are separated by a |. Do
not write graphs into the block.
| The vertical bar is the separator between two alternative parameters. Do not write this bar into
the block.
Parameters may be expressed by letters, alphanumeric characters and numbers. Letters are used
as keys or to identify the characteristic of a command. Alphanumeric characters identify file and
variable names and are used for messages. Numbers identify parameters, multiple elements, etc.
Non significant zeroes can be omitted.
Example:
(OPN, channel, filename, {A|B}, {R|W})
The three-letter code, the commas and the brackets are mandatory. A is alternative to B and R is
alternative to W.
The sections that follow describe ASSET functions. For each function the following information is
provided:
• Function name
• Meaning
• Syntax
• Mandatory and optional parameters
• Other characteristics and notes
• Examples.

LCK - Locking/Unlocking PLUS tables
This instruction permits to inform the logic or other applications that the specified table is being
edited and is not accessible to them. After the table has been edited it is necessary to give another
LCK in order to indicate that the table is available.
Syntax:
(LCK, table number, {0 | 1})
where:
table number Is a number from 1 to 4 that identifies the write protected table. It can be
expressed as a numerical value, a local variable or a system variable with the
following mening:
1 axes table (origins)
2 tools table
3 tool offsets table
4 user table (L variables).
0 | 1 Write 1 to indicate that the specified table is write protected by ASSET. If the
table is already reserved by another user, such as PLUS or Table Editor, an
error message will be displayed:
NC270 PLUS Table already locked
This error can be managed from program by setting ERR = 1. For more
information refer to Appendix B.
Write 0 to indicate that the table is no longer reserved for ASSET and can be
accessed by other users.
Characteristics
$xxxxxx or L variables are always accessible and need not be write protected with ASSET.
However, it is recommended to lock the table to make sure that no other user has access to the
memory area written by ASSET.
Use LCK to unprotect a table only when it has been write protected from part program. Otherwise,
you may unprotect a table that was reserved for other users (such as the machine logic).

INPUT COMMANDS
Input commands permit to create, customise and manage data entry windows. In particular, they
make it possible to:
• Define the labels of the data entry fields and the destination of input data;
• Define the layout of the data entry window: window size and position, text position, etc.
• Define the background, foreground and text colors.
The three-letter codes that allow to program these features are as follows:
• DIF
• INP

Chapter 2
Input Commands
DIF - Definition of a data field
DIF permits to define the size and color of a data entry window that has been programmed with the
INP command. It must be used when the characteristics to be configured are different from the
default ones.
Syntax
(DIF, window number, first line, first column, first field line, first field column, empty lines, number
of fields [,background color, text color, field color])
where:
window number identifies a predefined window. It is an integer from 1 to 10. DIF,0 invokes the
default window, which cannot be modified.
first line is the screen line where the data entry window starts. It is an integer from 0 to
18.
Line 19 is always reserved for error messages.
first column is the screen column where the border of the window is positioned. It is an
integer from 0 to 79 which must obviously be selected according to the length of
the displayed data.
first field line is the line occupied by the first window field declared in the INP block. This field
may be the name of the window or a data field.
It is a value in the 0 to 18 range which depends on the value of the first line
parameter.
first field column is the screen column occupied by the first INP field and measures the distance
from the screen border to the window border in characters. If programmed with
the INP command the field will be automatically centered.
It is an integer from 0 to 79 which must obviously be selected according to the
length of the displayed data.
empty lines is the number of empty lines that separates two subsequent comment or field
lines.
It is an integer from 0 to 18 which must obviously be selected according to the
available space and the length of the displayed data. If you write 0 there will be
no empty lines.
If INP programs only one data entry field, the empty lines value is use for
positioning the lower border with respect to the last displayed line.
number of fields specifies the number of fields to be displayed on the same line. It ranges from 1
to 4. The distance between two fields is 3 characters.
background color (optional) Defines the color of the data entry window background. If it is omitted,
the default background color is blue. Allowed values are between 0 and 7. The
meaning of these values is shown in the Characteristics section.
