PREFACE

This manual contains the description of all block functions (FB) needed for the logic application projects of the 10 Series CNC.

It contains the corresponding instruction list (IL) code for each FB and a description of the input and output variables.

This manual deals specifically with functions and function blocks. For further information on PLUS, its language and its applications in the 10 Series CNC environment consult the following manuals:

10 Series CNC PLUS APPLICATION MANUAL Code 45006677Z 10 Series CNC PLUS LANGUAGE & PLUSEDIT Code 45006672 P

You can find an FB or a function more easily if you look up the Function Reference List below in this preface.

In this list the functions are ordered alphabetically and for each of them there is a short description plus the page number.

In this manual the various function blocks have been subdivided into groups depending on the type of operation they fulfil or the environment to which they belong. So if you do not know the exact name of an FB, but know the environment to which it refers, you can easily find the FB in the manual by consulting the index.

COMMON FEATURES OF FUNCTION BLOCKS:

All function blocks can be used in the Ladder Diagram / Function Block Diagram (LD/FBD) editors and in the MACRO Instruction List (MACRO-IL) editor. The function blocks discussed in Chapters 1 and 3 are base function blocks i.e. built from standard elements of the instruction list (IL). All the other function blocks are extensions which internally use a function call. These functions can also be used in the IL editor. For each FB there is an example for the calls and the necessary parameters in IL.

NOTE:

When using function calls in IL, there is no control to ensure that the number and type of parameters are correct. When using the MACRO-IL editor, the function block parameters are always checked.

Preface

enable input Many of the function blocks shown in this manual have an “enable” input which enables/disables the

execution of the block.

• Enable is a Boolean variable which can be inverted if necessary.

• You can link all types of Boolean variables available in PLUS including the Boolean constants KB1

and KB0.

• The enable signal linked to the FB P1 (pulse) or the use of FBs for controlling the program flow allows you to write faster and attain a more efficient machine code. In general it is better to try to limit the number of always enabled FB (enable always = 1) by disabling them when their function is not required, in order to increase the performance of the machine logic.

stat_wrd output (function status output word) The function status output is available on all system function blocks. After the relevant function has

been completed, this word contain a value indicating that all went well or that there was some kind of problem. When everything was ok, the status word will be zero. In case of problems the value of the status word is different from zero. Please refer to the specific function block for the meaning of the values returned in the status word. Often you're not interested in knowing the status of the functions because your program has been tested and always works well. You can then hook up only one single short variable, e.g. MW 999, to the status output of many functions.

ax_id input (physical axis identifier) The axis identifier is used for many system functions. It is a number identifying the internal resources

for one axis on an axes module. Each axes module supports 8 axes, 6 resources are reserved for physical axes (which read encoders and/or write to D/A converters) and 2 for virtual axes. A machine axis (e.g. "X") may be related to any of the available physical axis resources on any of the axes modules. There can be up to 4 axes modules in the 10 Series CNC chassis, allowing for up to 32 axes (theoretically). The axis identifier now, is a number in the range of 1 through 32. It must be assigned during the axes configuration in AMP and will also serve to define the page number of the axes table on which this axis will be managed. Even when you move the physical connections (encoder, D/A) of an axis to another axes module, its ax_id will remain unchanged and the axis data will remain available on the same page of the axes table. The function A_TO_ID converts an ASCII axis address to its physical axis identifier number.

tc_id input (transducer/converter physical identifier) The identifiers of the tansducer inputs are numbers in the range of 100Hex up to 1nnHex. On the first

servo module you will find (top to bottom) the transducers 100Hex through 105Hex, on the second 106Hex through 10BHex, on the third module 10CHex through 111, and so on. The D/A converters have a similar numbering system. On the first module you will find the converters 200Hex through 205Hex, on the second module 206Hex through 20BHex, and so on.

symbolic names Symbolic names to be associated to the user subroutine (DSRB) and to the label (LBL) must be

different from those predefined in PLUS (FB names, predefined routines, etc.) and should never begin with a $. Furthermore, symbolic names should always begin with a letter and not with a number.

TYPES OF SYSTEM FUNCTION CALLS

There can be 3 different types of system function calls (system function blocks):

WAIT

A WAIT function call suspends the execution of the task that called it. This task will resume its activity after the function has been completely executed.

The suspension of a task implies the suspension of all routines that make up this task. The WAIT function is normally executed by an environment other than the I/O processor module (the system).

For this reason a WAIT function is a synchronous call: when the logic scan exits from a WAIT function block, this block has been completely executed.

NOWAIT

A NOWAIT function call does not suspend the execution of the logic task that called it. Immediately after the call has been issued, the logic task resumes execution. The function call will be executed by an environment other than the I/O processor module (system).

For this reason a NOWAIT function is an asynchronous call: when the logic scan exits from a NOWAIT function block, the function is still being executed by another environment.

The execution of many NOWAIT function calls from a logic task may cause a system overloading since the simultaneous execution of many functions is required.

When 15 NOWAIT functions are in parallel execution, the function that has generated the last call is in any case executed and it returns to the word status a warning code (1000 hexadecimal).

If you continue to call NOWAIT functions after the warning message, that is when 25 functions are in parallel execution, an unrecoverable emergency is generated ("too many requests").

INTERNAL

An INTERNAL function is similar to a WAIT function call but its execution is much faster because it's done by the same environment that calls the function (PLUS). An INTERNAL function call is in all aspects like a subroutine available to the PLUS environment. For this reason an INTERNAL function is a synchronous call: when the logic scan exits from an INTERNAL function block, this block has been completely executed.

BASIC LANGUAGE FUNCTION BLOCKS

The basic language function blocks are the direct equivalents of the corresponding instruction list elements. Every time you use one of these function blocks, its internal (IL) code will be inserted in your program. In this sense the basic language function block behave like macros. The function blocks discussed in this chapter do not call any functions. Each one of the sections in this chapter covers a group of function blocks which all work on the identical data format.

Those function blocks which internally use a system function call are covered in the other chapters of this manual. They are called language extensions because they expand the capabilities of the language beyond the capabilities of the single instructions.

For each of the basic language function blocks you will find a table which contains the attributes of the inputs and outputs of a function block. The columns in this table are:

NAME : Name of the connection INVERSION : Indicates whether the input or output can be logically inverted. This attribute

is only available for Boolean connections.

DUPLICATION : If this attribute shows yes, you are allowed to make one or more copies of

this connection. Each one of the copied connections will have the same attributes as the original and the connected variable will be processed just like the original variable.

FORMAT : The format of an operand to be connected to an input or an output can be

one of:

Boolean only bits allowed short 16 bit integer operand double 64 bit floating point operand char string or string constant all no check, all formats possible special for special operands NAM and LAB only

As you enter an operand for a function block, it will be checked if it matches the required format.

GROUP : The different types of operands are divided into groups. For certain function

block connections some groups will be excluded (e.g. it is not allowed to connect an input to a Boolean function block output). The letters in this column indicate which type of operand may be used:

WARNING

Basic Language Function Blocks

M M variables (depending on the format you must select M Boolean

MW -> short MD -> double).

G global retentive G variables (depending on the format you must

select G -> Boolean, GW -> short or GD -> double).

S System flags or S variables. (again, select the S or SW

depending on the format of the connection; S -> Boolean or SW > short)

T Timer variables. T or TW depending on the format (T -> Boolean,

TW -> short).

C Counter variables. C or CW depending on the format (C ->

Boolean, CW short).

K Constants. KB -> Boolean, KW or KH -> short, KD -> double. X local variables. Select X -> Boolean, XW -> short or XD -> double,

depending on the format of the connection.

Y subroutine parameters. select Y -> Boolean, YW -> short or YD -

> double in accordance with the format of the connection.

A ASCII string variable. #" Text constants. NAM subroutine names, PLUS routine names LAB label names

Double constants (KD) are defined with the following format:

KD ± x.yyyyE ± zzz

The decimal part yyyy must always be written in full (4 figures).

IMPORTANT

Basic Language Function Blocks

LINE ELEMENT

The line element can be used to "connect" a variable or a constant (left side) with one or more other variables (right side). The variables (constants) on both sides must have the same type (i.e. short). The line element is only available to connect Boolean, short and double variables and constants.

Examples:

short constant c onnected to short variable s

KH00FF

Boolean constant connect ed to boolean variables

KB1 O 24,03

Short constant connected to a timer preset word

KW100 TW 020

MW 200 MW 201

G 010,00

Of course you cannot connect inputs and/or constants to the right side of a line element. For an explanation of how to insert a line element please refer to the Plusedit manual.

When you design a logic program using Function Blocks please consider some rules related to “broken” Line Elements. We will explain this using an example:

GD 00 I 00,00

SE TD I1 En

GD 01

The use of a 'broken' line element in this example forces the PLUS development package to assign an automatic variable (MD 151) for this line. This variable will always be assigned to the destination variable GD 1, independent of the status of I 00,00. The translation of the block shows clearly why:

As you can see, the assignment of MD 115 to GD 01 is not conditioned by the input I 00,00 of the Function Block SETD.

To avoid this probably undesired behaviour you should connect the destination variable GD 01 using a straight line:

G D 00 I 0 0,0 0

S E T D I1 E n

G D 0 1

Using this straight connection, the translation in IL does not require an automatic variable:

Please keep in mind these considerations when using FB programming:

• The use of 'broken' line elements as explained above can cause 'abnormal' behaviour of your logic

program. Problems due to an unwanted assignment as in above example

• Broken' line elements use automatic variables and generate extra code which requires more

memory and more execution time.

• Avoid to use 'broken' line elements to keep your logic as fast as possible.
