Preface

10 Series CNC WinPLUS Application Manual

PREFACE

The 10 Series numerical control introduces many new Technical concepts. One of the most important of these concepts is the concept of information exchange between the CNC and the integrated PLC (Programmable Logic Controller).

Conventional controls use a window with a large amount of fixed flags, which are continuously scanned and updated by both CNC and programmable logic control.

The concept of 10 Series by-passes this general conception with a simple but unique solution: both CNC and PLC use function calls to alert each other, to pass information or to request a certain action. These function calls need only be executed on event, thus freeing up CPU capacity and increasing the general system performance.

This manual explains the new concept and shows how applications can use its power.

ABOUT THIS MANUAL

This manual is intended to be used by the OEM personnel in charge of the programming of the machine tool interface. It gives an overview of the software architecture to be used to develop the programmable logic.

• it does NOT explain the WinPLUS programming language and the use of any of its language elements.

SYSTEM - APPLICATION LOGIC HANDSHAKE

Logic Buffer Interface

Chapter 1

Fig. 1-1 System - Application Logic Handshake

THE LOGIC INTERFACE BUFFER – THE M RACK

The system communicates with the logic through a logic interface. This interface is a data buffer in which the system writes the data to send to the machine logic program.

The data buffer is divided according to its functions in different parts called RACKS.

They are always active.

M Rack

10 Series CNC WinPLUS Application Manual (00) 1-1

Chapter 1

System - Application Logic Handshake

SYSTEM FUNCTION CALLS

The logic from its part communicates with the system through a set of function calls which can include a parameter exchange between the two parties. There are two types of function calls:

• NO WAIT functions pass a command (with parameters) to the system without waiting for an answer (the application program execution is not suspended).

• WAIT functions pass a command to the system and wait for a response ( the logic execution is suspended until the response arrives)

COMMON DATA AREAS

The third communication channel between the logic and the system are the common data areas in the battery buffered dual ported memory of the I/O processor board. These areas can be divided in:

• System area. This is a group of 500 variables of the type short (16 bit integer word) containing the status of the system and/or the processes.

• Global variables. These variables are referred to as "G" variables. They have two formats; short and double (precision floating point). They can be read and written by both part program and logic program. The G variables are retentive, i.e. they are not cleared after powering up the system.

• Tables. Tables are retentive memory areas in the dual port of the I/O processor module. They can be commonly accessed by the system and by the logic programs. The data contained in tables includes:

− tool data

− tool offset data

− axes origin data

− axes offsets

1-2 10 Series CNC WinPLUS Application Manual (00)

Chapter 2

ORGANIZATION OF THE MACHINE LOGIC PROGRAM

The logic program is organised in independent routines. All these routines run on the I/O processor module and have different priorities depending on their use.

The various routines are activated by the operating system of the PLC following specific events, or at given times, or may also be run continuously (in loops).

AVAILABLE ROUTINES

Routines activated on time (foreground)

This routine (only one can be present) will be executed on each clock tick of the I/O processor module. This clock tick is currently set at 10 ms. If the foreground routine execution time exceeds the available time (max. 10 ms), the system will generate an "overrun error" and go into emergency status. The routine must have the shortest execution time possible (<5 ms) because the remaining TICK time is used by routines with a lower priority. The primary use of the foreground routine is to "latch" events to be executed with fast, precise timing such as read/write physical I/O device status or handling of security/emergency devices. Requested name for the routine :fore.

Continuously executed routines (background routines)

A background routine executes continuously in a loop like a program in a standard PLC. The I/O processor can run up to 12 background routines in parallel.

Each background routine can execute functions of the WAIT type, which will suspend the execution of that background routine until arrival of the response. In the meantime the other background routines will continue executing. In reality, when one routine is suspended, control passes to the next one.

The logic programmer has to optimise the performance of the I/O processor by distributing the logic in the available background routines. Requested name for the routine : back1 …back12.

10 Series CNC WinPLUS Application Manual (04) 2-1

Chapter 2

Organisation of the Machine Logic Program

Routine activated in an emergency

This routine can be recalled whenever an emergency condition occurs. It can be activated only if it has been loaded. In an emergency, the logic application may have to execute logic sequences in parallel with the actions performed by the system. Mandatory name for the routine:

EventTaskEmg.

Routine activated by pressing a softkey (OEM softkey routine)

This routine is called whenever an OEM softkey is pressed (or released).It can be activated only if it has been loaded.

The OEM softkeys are defined in AMP, enabling the OEM to provide its application with the same appearance and operability as are typical of the standard system (AMP configuration manual). The management routine of an OEM softkey works at a very low priority level. Mandatory name for this routine: EventTaskHum.

Routines activated by part program events (part program interface)

Specific routines (one for each process configured) are called whenever a part program block contains functions relating to the logic (e.g., M codes, S and T functions, and all the other functions that can be grouped under the heading of ancillary logic functions). These routines can be activated only if they have been loaded. Mandatory name for these routines: EventTaskPPX, where X stands for the name of the associated process.

Routines activated from the console (request for enable signal)

Specific routines (one for each process configured) are called whenever a command is imparted to the system (e.g., cycle start, reset, etc.), enabling the logic to read and/or suspend the commands imparted to the system by the operator. These routines can be activated only if they have been loaded.

These routines are provided for most of the commands that can be entered via softkeys and/or from the MTB panel. Mandatory name for these routines: EventTaskConX, where X stands for the name of the associated process.

Routines activated when requested by the logic

Specific routines (from 1 to 39) will be called whenever the logic notifies an event through the SetEventTask function. Once activated, these tasks will be completed through the end.

Mandatory name for these routines: EventTaskLogX, where X stands for the task number.

2-2 10 Series CNC WinPLUS - Application Manual (04)

Chapter 2

Organisation of the Machine Logic Program

Routines activated by Fast Input Events

A routine that is available following activation of a fast input.

This routine will be activated only if it has been loaded. The application logic understands what Fast Input has been executed. To understand which input has been executed refer to the following table.

MW9990

Bit Event

0 Fast Input#1

1 Fast Input#2

2 Fast Input#3

3 Fast Input#4

4-15 Reserved

If two Fast Input events occur at the same time, the routine will be called twice.

Mandatory name for the routine: EventTaskFIN.

ANALYSIS OF RACK M

The data supplied from CNC to the logic is written in RACK M every time that the data is memorised in the interface buffer interrupting the execution of the Background routine for the necessary time that it takes to be written.

TASK SYNCRONISATION

The background routines can be synchronised with a set of semaphores (32) with the WAIT and SEND instructions. With the WAIT instruction and a semaphore number (from 0 to 31) it is possible to suspend the execution of a routine (task) until one of the other routines executes the SEND instruction with the same semaphore number . In this way it is possible to synchronise the execution of a task with another event in another task.

10 Series CNC WinPLUS - Application Manual (04) 2-3

Chapter 2

Organisation of the Machine Logic Program

Fig. 2-1 Task synchronisation

The instruction WAIT (3) suspends the execution of the BackProgram1 task until the command SEND (3) in the BackProgram2 task executes. Naturally the exact point (in time) of task resume depends on its priority.

Chapter 2

Organisation of the Machine Logic Program

NOTE:

If a SEND on a semaphore is issued without a task waiting for this semaphore. The SEND instruction will be ignored. Any routine in WAIT status can only be released by the equivalent SEND instruction. The routine containing the SEND instruction must be synchronised with the routine containing the WAIT status request.

IMPORTANT

You are not allowed to use the WAIT/DLY instructions in foreground, fast input and emergency routines

The use of the SEND and WAIT functions for synchronisation can produce some inhibits to the system if used during the management of the Part Program functions:

RQP RQT TOU GTA GTS

The problem can happen if the task that performs the SEND to the routines managing the functions in the list above also performs process applications (for example NC functions for position or status acquisition).

If they are wanted to use criterions of synchronism founded on WAIT and SEND it it is necessary to make sure that the task that sends the SEND doesn't perform any application toward the NC process. It is suggested that an ad hoc task is created that verifies the conditions of acceptance of the applications (e.g. possibility to use the in demand axes through GTA) and you effect the SEND to unhook the task applicant.

When low priority events occur, like consent request calls, part program Interface calls or even OEM softkey calls, the foreground routine and all other higher priority tasks will not be interrupted. These low priority routines will only run during the time available for background logic execution.

10 Series CNC WinPLUS - Application Manual (04) 2-9

Chapter 2

Organisation of the Machine Logic Program

BACKGROUND EXECUTION

There can be up to 12 background routines. The background routines are those with the lowest priorities among the routines making up the application logic and are executed in turn every 10 ms (WinPlus Tick) for 1 ms. At each WinPlus Tick the integrated PLC updates the I/O's and the foreground routines. Consent routines, part program interfaces and OEM softkeys are enabled at system request and interrupt background execution.

After enabling all high priority routines at each WinPlus Tick, the system enables one of the background routines and lets it run for 1 ms. At each WinPlus Tick the system enables a different background routine. The sequence of activation is determined by the number associated with the routine name. At the first WinPlus Tick the background routine 1 (BACK1) is enabled, at the second the background routine 2 (BACK2) and so on. Once the last background routine has been enabled, the system starts again with the first.

Therefore, an individual background routine is executed over several WinPlus Ticks, alternating part of its code with that of other background routines in time slicing. If a background routine suspends its execution voluntarily by calling a function such as WAIT or DELAY or indirectly by calling system functions of the WAIT type, the remaining time up to the end of the millisecond is available for other system operations (processing a part program, displaying, etc).

If a background routine is shorter than 1 ms, it will execute several times during the WinPlus Tick. If the background task to be enabled is suspended at a new WinPlus Tick, no other background routine is executed and the millisecond reserved for it is used by the system.

Fig. 2-6 Background logic execution

Fig. 2.6 shows 3 background loops with total execution times of 3, of 0.5 and 2 ms respectively.

10 Series CNC WinPLUS - Application Manual (04) 2-11

Chapter 2

Organisation of the Machine Logic Program

As can be seen, at each cycle a different background routine is started, which means that a short background routine is executed more often than a long one.

Referring to the example, the repeat frequency of the 3 loops will be:

$BACK 1 90 ms $BACK 2 30 ms $BACK 3 60 ms

The formula for calculating the frequency of a background routine is:

duration of the background routine x number of background routines x 10

IMPORTANT

In this example it is assumed, that there are no interrupts (fast inputs, OEM softkey, requests form a part program or from the operator)

I/O PROCESSOR /SYSTEM DATA AREAS

The I/O processor and the system share a data area in the dual port memory of the I/O processor module. This data area contains an I/O image, global retentive variables (G), system status variables and 4 retentive tables with machine tool related data. Fig. 3-1 gives a detailed overview of all data areas on the I/O processor, which are available to the application logic.

SYSTEM STATUS FLAGS

There are 500 system variables. They all have the short format. The first 20 variables (SW 00SW 19) are used to exchange some general system information between the logic program and the system. Since the purpose of these variables is predefined, they have predefined symbolic names. Most of the variables are read only by the logic (R/O). Only SW 03, SW4 , SW7 and SW12 can be written and read by the logic (R/W). SW Variables can be managed as words (I) or as single bits (B) or both (B/I).:

PROCESS STATUS FLAGS

All words in the process flag window have mnemonic names that start with the process number. Prefixes from S_1 to S_20 for the processes from 1 to 20. For each process there is one group of 20 words. Each group is identically structured. The access to process variables is as discussed for the system variables. For each process there will be a group of flags as for process number 1. The functionality is identical, the mnemonics are different only to the part relating to the number of the process. The symbolic addresses SW nn must be incremented by 20 for each further process.

These flags are dynamically updated. They are not synchronised with the

CAUTION

execution of the logic (except S_nRESE and S_nHOLDA). Therefore, do not use these flags to synchronise the logic: the signals may change state during the execution of a routine.

Title: Active paramacro G code

The variable provides the number of G-code of the active paramacro. In case of paramacro nesting the paramacro G that is passed is the last programmed one.

IMPORTANT

For the G-codes G00 up to G99, there are 100 reserved bits in the dual port memory. The G-codes are divided into groups. In one group only one G-code can be active. The different groups are indicated by the letters a-m. The Gcodes with the "*" are non-modal, i.e. they are only active for the duration of the part program block they were used in.

S_nSTOPR is set TRUE before the axis' return movement and it is set false at the end of

the boring cycle.

NOTE:

30 ms of time are required at least, from the moment we set at 1 the value and the moment of the axes’s return movement. This time is used by the logic machine to analize the connect strategy to use (ex.: stopping the axis for a long time before returning to allow the spindle stop).

S_nTRAP is set TRUE during the rapid approach phase of the touch probe cycles G72,

G73 and G74. It can be used to clean the workpiece surfaces with compressed air.

USER DEFINED / GLOBAL VARIABLES (G VARIABLES)

In addition to the system flag area and the process areas there is one memory area reserved for user defined variables. These variables are retentive, i.e. once stored, they will not be cleared at power turn on, unless they have been configured to be changed to a specific value by AMP. The variables in this memory area are called G-variables. There a 2 formats of G-variables:

• 16 bit words (value -32768..0..32767) (you can also address the individual bits of these variables)

• 64 bit floating point (double) variables

GW 000

GW 255

GD 00

GD 63

Fig. 3-2 "G variables" memory area

Since the G variables are accessible by the system and by the I/O processor, you can not only use them in the logic program but also in a part program. In this way they can serve as a direct communication channel between the part program and the logic or between the logic and the part program. To make one or more of the variables available for part programs, you have to define them in the AMP configuration program. In order to simplify access, you must assign a logical name to the "physical" address. All logical names for variables in this area have to begin with the "@" character.

AMP allows 3 types of variables to be configured:

• Boolean (max. 128) You can assign any bit (0-15) of the G variables (0.255)

• Short (max. 64) You can assign any of the 256 GW variables (000..255)

• Double (max. 32) You can assign any of the 64 GD variables (00..63)

In AMP it is possible to assign a value to these variables that is loaded every time you switch on the system.

The following examples show an assignment for each of the possible variable types:

Examples:

@POS = G 006,04 (Bit 4 of word GW 006) @SPEED = GW 200 @ACC = GD 18

Chapter 3

I/O Processor /System Data Areas

@ = GW3 (a value can be assigned in AMP, but the variable is not available to the part program

M VARIABLES

The M variables are part of the "memory work area" for the logic.

They are divided logically into two parts:

• User’s area (the work area memory for the logic) 6950 MW and 1950 MD variables

• The M RACK (exchange and request data buffer between CNC and logic)

There are 10000 variables of short type (MW0 -MW9999) and 3000 variables of the double type (MD 000 - MD2999) of which 50MW and 50MD are global (not reserved to a particular process). 150 MW variables and 50 MD variables are dedicated to each process (max 20),.

In general the M RACK is divided functionally into parts that are called RACK. Each of which is composed of a group of variables (read and write) “dedicated “ to a special function.

CAUTION

The system cannot access the M variables directly.

NOTES:

• These variables are NOT retentive! They will be cleared at power turn on.

• The variables MW 0000 - MW 4999 can be addressed as words (MW xxxx) or also as single

bits, (Mxxxx,yy) or as entire MIxxxx .

• In case the processes are less than 20, the variables that otherwise would be dedicated to the concerning process are available, like the user M, MW or MD variables.

The operations that can be executed on the M RACK must follow the rules described in this manual

TABLES

In the DUAL PORT memory, 4 table are available:

• AXES TABLE

• TOOL TABLE

• TOOL OFFSET TABLE

• USER'S TABLE

These tables are persistent: once they are memorized they are not deleted when the system is switched on.

Axes Table

The axis table can contain up to 32 pages. Each page contains information regarding one specific axis. This information is divided into fields:

etc..

Fig. 3-5 Axes table (one page per axis)

10 Series CNC WinPLUS Application Manual (03) 3-19

Chapter 3

I/O Processor /System Data Areas

There is one page in the table for each configured axis (co-ordinate, point to point, transducer-only axis, spindle and virtual axis). The page number of an axis corresponds to its physical identifier as defined in the AMP configuration. The system supports up to 32 axes, so there are 32 pages in this table and 32 physical axes identifiers (1-32).

You can select one of the pages of the axis table with the physical axis identifier of the axis. If you only know the axis name ("X", "Y", etc. in the AXNAME field) and process (AXOWNER field), you can use the function A_TO_ID to find the corresponding physical identifier. The field AXOWNER defines which ambient actually controls that axis:

There are 250 pages in the table for up to 250 tools with tool magazine option; it is possible to assign 250 tools to one or more tool magazines (up to 10). You can access a page of the tool table with the page number (1-250) or if you use the TBLSRCD function also with the tool identification code. Since the data for a specific tool may be in any of the 250 pages, it is better to use the method which uses the TBLSRCD function.

The TBLSRCD function/ function block/ macro can be used to find the page number of the tool table for a given tool identifier:

Fig. 3-8 The table search function block (double search)

In above function block the inputs “n_tab” e “n_field” define the Number of the table and the field to search. The input “srchaval” is connected to the searched tool id, the tool identifier as programmed in the part program. The inputs “n_start”and “n_stop” indicate the first and the last table page in which the input “srchval” is searched. Generally you will use 1 as the start index and the maximum number of tools as the stop index.

For example, you will use different ranges in case a tool table is subdivided in areas, each belonging to a single process.

The system will write the data for each one of these part program information groups into the relative M RACK if this has been enabled in the configuration Rack by the WinPLUS programmer.

NOTE:

It is not necessary to enable all of the Racks.

If the system detects that one of these is not enabled, it will be assumed that the logic is not interested in that particular feature of the part program and, it will continue the execution of the block without updating the Rack data..

Even if they are optional, some RACKS like the M,S,T, functions, must be enabled so that the 10 Series CNC will execute the M codes, the spindle speed, and the tool management. correctly.

Logic System Communication

THE PART PROGRAM INTERFACE RACKS

Each Rack of this group will be updated every time that an associated request is found in the part program.

The requests from part program (or MDI) can be:

Request Associated Rack

Programming of axes movement Movement consent, end of movement

Programming code M M functions

Programming code S S functions

Programming code T T functions

Programming pseudo axes Pseudo axes

End of the block End of Block (EOB)

inserting tool offset RQP

Inserting correction for tool wear RQT

Tool worn TOU

Completed probing cycle Probing end of cycle

Shared spindle activation GTS

Program activation Program Activation SPG

Programmed axis migration GTA

The task of these interface Racks is to allow the logic to manage the information that comes from the part program and to start actions related to them.

For each request, the system prepares the data at the specific Rack, activates a strobe to signal the presence of new data to the machine logic and then waits for the logic to acknowledge completion of the action. .(ACKSTROBE).

The system is left in a wait state until the acknowledgement is received, the wait state is then released and the associated strobe signal is disabled.

It is possible for the machine logic to release the suspended part program execution before the completion of the logic action, by sending the appropriate acknowledge. E.g. A T word might be acknowledged before the completion of a tool search, if the tool storage system is independent of the rest of the machine. In this case the logic would acknowledge the T strobe as soon as the new value was recognized.

NOTE:

All the functions that you will find in this chapter (functions M,S,T, consent to movement, end movement), are described assuming a sequential management of the request (e.g. fig. 5-2: the part program restarts execution only at the completion of the handling of the function).

COORDINATED AXES

There are 9 possible motion axes in a process. 6 of the 9 axes can be programmed simultaneously in a single part program block. In the case of dual axes, up to 9 axes may be moving with only 6 axes programmed in the block. Each of the axes has a part program address (axis name) which must be defined in AMP. The numerical value which is programmed after that address (the position) is a (double precision) floating point number which has a format of 5.5 (5 figures before and 5 figures after the decimal point). There are two calls from the system to the logic related to co-ordinated axes motion:

• Consent to motion

• End of motion

Consent to move Rack

Warning Both this rack and the GTA rack share the same information and MW variables.

The “Consent to move” Rack data is always updated when the system encounters a block of axis movement during the execution of a part program,. When this happens the variable “motion consent strobe” is set to 1 while the data related to the axes in use is stored. The logic has to check if this axis is allowed to move. The axis motion will not be started until the logic responds with an acknowledge to the system. The inputs and outputs of this Rack are:

INPUT VARIABLES:

MW(K+5) Type of motion (short) MW(K+6) Type of fixed cycle (short) MW(K+7) mode (short)

KW(K+8) axis identifier of 1st configured axis (short) ……..

MD(L+9) end position of 9th configured axis (double)

OUTPUT VARIABLES:

MW(K+4) task return value (short)

To know how K and L are obtained see Chapter 4.

To acknowledge “consent to movement” to the system it is necessary to insert the following call in the user’s logic:

Motion blocks

A motion block is a part program block or a group of part program blocks containing programmed axes motion from the actual point to the programmed end point without any commanded stop inside the motion.

A motion block can be:

• an axes motion in G00

• a programmed motion in G01, G02 or G03

• a continuous path (profile) in G27 or G28. In this case the motion block may consist of more

than one part program block.

• a fixed cycle (like G81, G83, etc.)

• a fixed cycle like G84 or a part program block in G33

The system communicates with the logic at the beginning of a motion block by starting the “consent to move” routine in the interface system-logic Rack. At the end of the motion block the system will communicate to the logic “Block end” through the strobe bit “end of motion request” of the “Interface system-logic” Rack (motion end).

If there should be a continuous mode block, that would mean that the first block must contain all the axes that are part of this motion, even if this means repeating the current position. Only in this way can the system inform the logic about the axes involved in the motion block.

Example:

G 00 X 10 Y 10 Z 10

G 01 G 27 X 20 Y 20 Z 10 F 1000 <-- Z declared even if

MOTION X 30 no motion in this

M FUNCTIONS

The M code followed by a number identifies an auxiliary function relating to the machine tool. In the 10 Series CNC the M code value must be a positive integer with up to 3 digits (0...999). The

programming format for the M code is therefore (M0.....M999). You can program up to 4 M codes in

a part program block.

M functions may have different characteristics, which must be specified in the AMP.

There are 3 types of M functions:

• Prelude M functions are sent to the logic before axes motion

• Expedite M functions are sent to the logic during axes motion

• Postlude M functions are sent to the logic after axes motion

In prelude and postlude M function synchronisation between axes moves and execution of M's by the machine logic depends on:

• how the accepted in continuous mode parameter has been configured

• the type of motion (G27, G28 or G29)

Motion Code accepted in continuous mode = N accepted in continuous mode = Y

G27,G28 Not possible M function execution synchronised

with axes moves. No handshake required (the function is sent to the logic without interrupting program execution).

G29 M function execution synchronised

with axes moves. Handshake required (program execution interrupted as long as it is requested by the logic).

M function rack

Each time a M function is encountered in the part program the “M function” Rack data is updated; the variable “strobe M prelude/postlude” is set to 1 and the other input data relating to the M are stored (type and code).

The logic must send an “accepting code M” answer using the special function so that the execution of the part program can continue.

In the case of M expedite functions the value of M function is updated in the “Expedite M code emitted” rack

The input variables of this Rack are:

INPUT VARIABLES:

MW(K+19) type of M code (short) MW(K+20) decimal value of code M (short) MW(K+21) decimal value of M expedite (short )

OUTPUT VARIABLES:

MW(K+18) return value of routine (short)

Description:

The type (MW(K+19)) of code M can have the following values:

0 => code M prelude 1 => code M expedite 2 => code M postlude

NOTE:

When starting the machine these variables are homed. The logic must always send an answer to the system following code M through the function “accept M code ”.

To send the answer “accept M function ” to the system it is necessary to insert the following call in the user’s logic.

The can acknowledge or refuse the M code request. If a certain M code is not allowed with the machine in a particular state, the logic can return a -1 value in the XW 00 variable. The system will go into error status. Another reason to refuse an M code could be a mechanical problem during its execution.

When a RESET coincides with the execution of an M code, the logic must send an acknowledgement to the system anyway. The logic may decide to abort or to continue the further execution of the M code. Never forget to acknowledge a pending M code during a reset, as this will inhibit execution and prevent the reset from being completed. Note that the M code acknowledgement must be executed before the ENDRESE function may be called. For more details refer to the reset management. When a HOLD coincides with the execution of an M code, the system will not execute any further (MDI) M-codes, until it receives the acknowledge for the pending M code.

M code management (EXPEDITE)

The system allows the use of only one expedite M function in each part program motion block.

Because there is no synchronisation for expedite functions, expedite M codes must be processed by the logic as fast as possible. The throughput of part program blocks containing an expedite function may be very high (block cycle time!). By making the execution as fast as possible, the risk of losing expedite M codes when working with a very low block time is minimized.

AMP set up for M functions

Each M function allowed in the system has to be set up in the AMP software configuration program. The characterisation for M codes is used by the system when an M code is encountered in the part program. When an M code is programmed, which was not defined in AMP an error will occur.

This is the list of items which can be assigned to M codes in AMP:

Activation mode: PRELUDE / POSTLUDE / EXPEDITE

This attribute tells the system when to notify the logic about the M code. Prelude means before the motion of the block starts, postlude is after the motion of a block has finished and expedite means that the logic will be notified during the motion. (i.e. M03, spindle clockwise, will have the attribute prelude, M 06, change tool and tool offset, will be executed postlude)

Allowed in hold: Y/N

This attribute tells the system that the related M function can or cannot be executed and notified to the logic in the hold status. M06 is an example of a code which cannot be accepted in hold.

Visualisation: Y/N

This attribute defines whether or not the system will display the M code on the main screen.

Modal function: Y/N

This attribute refers to the display of an M code. If you declare the function modal, its code will also be displayed during all subsequent blocks. A non-modal function will only be displayed during the execution of the block it was programmed in. ( i.e. typically M03 is modal, M06 is not)

Display after reset: Y/N

This attribute tells the system if the display of the M code must be maintained after a reset. When set, the logic must also maintain the M function active, even if a reset occurs.

Force conditional blk/blk: Y/N

This attribute can be set true for postlude M functions only. When an M code with this attribute is executed and the system variable USO is set true, the system will go into "block by block" mode at the end of the block. The state of "USO" is defined in the "PART PROGRAM SETUP" menu. This attribute is normally used for the M01 (optional stop) code.

Force unconditional blk/blk: Y/N

This attribute can be set true for postlude M functions only. When an M code with this attribute is executed, the system will go into "block by block" mode at the end of the block containing the M code. This attribute is normally used for the M00 (programmed stop) code.

5-18 10 Series CNC WinPLUS Application Manual (04)

Block calculation stop: Y/N

This attribute can be set true for postlude M functions only. When an M code with this attribute is executed, the pre-calculation of the next part program block is stopped. In this status, the system can accept other motion commands from the logic, like MDI or subroutine calls (i.e. to execute a M60 pallet change with motion of the co-ordinate axes). The normal part program execution after a block calculation stop can be resumed with the PPRESUME function call.

Tool offset change: Y/N

This attribute can be set true for postlude M functions only. When an M code with this attribute is executed, the system will be prepared for a change of the tool offset. It must always be combined with "block calculation stop=Y". This attribute is normally used for the M06 tool change M code.

Reset after execution: Y/N

This attribute can be set true for postlude M functions only. When an M code with this attribute is executed, the system will automatically perform a RESET at the end of the block. Normally this attribute is used for codes like M02 or M30 (program end).

Display class: 0....15

This attribute tells the system how the M codes must be grouped for their display on the screen. For example the codes M03, M04 and M05 belong to the same group, are mutually exclusive and can be displayed in one screen position.

During their execution, M codes will appear on the screen in reverse video mode. In the moment in which the logic acknowledges the M code, the display of the M code will be returned to normal.

Search in memory class: Defines the priority for the emission of the M functions at the end

of the search in memory command. There are 16 classes of priority. The emission of M functions is carried out as follows:

- class 0 means that the M function will not be memorised

- at the end of the search the functions that have the lowest

class number will be emitted first.

Accepted in continuous mode: Y/N

This parameter specifies whether or not the M function may be programmed in continuous mode. It can be set to Y only for functions that do not require "forced block to block", "calculation stop", "offset change" or "reset".

PSEUDO AXES

Pseudo axes offer an easy-to-handle interface between the part program and the logic. The pseudo axes are part program addresses (like axes addresses) which can be used to transfer numerical information (in double precision floating point format) to the WinPLUS program. This information can be used by the logic to control analogue outputs or point-to-point-axes.

The part program addresses (axes names) of the pseudo axes must be defined in the AMP configuration utility. AMP will allow up to 6 addresses to be defined as pseudo axes. The names used must be different from the other axes names. The programming format for pseudo axes (like for normal axes) is 5.5 (five figures before the point and five figures after).

Pseudo axes rack

If the “Pseudo axes” rack is enabled (in the configuration Rack), the data of this Rack will be updated each time there is a Pseudo rack in the part program execution.

Correspondingly the variable ”Pseudo axes function strobe request” is set to 1 while the other input variables contain the data concerning the related axes.

The logic must send an answer “acknowledge programmed pseudo axes”, using the proper function, in order to continue the part program execution.

The input and output variables of this Rack are:

INPUT VARIABLES:

MW(K+23) axis identifier for the first configured pseudo axis (short)

..... .........

MW(K+28) axis identifier for the sixth configured pseudo axis (short) MD(L+11) programmed value for the first pseudo axis (double)

..... .........

MD(L+16) programmed value for the sixth pseudo axis (double)

OUTPUT VARIABLE:

MW(K+22) task return value (short)

To send the answer” acknowledge pseudo axes function” to the system it is necessary to insert the following call in the user’s logic:

5-26 10 Series CNC WinPLUS Application Manual (04)

Chapter 5

Logic System Communication

If the value of a pseudo axis identifier (one of the parameters from MW (K+23) to MW(K+28) is zero, then the corresponding pseudo axis is not programmed in that block. The sequence of the pseudo axes addresses in the words MW(K+23) to MW(K+28) is the same as that of the sequence configured in AMP.

S FUNCTION

The part program uses the letter "S" as code for the spindle speed. The S function can be used to program the spindle speed in RPM or the workpiece surface speed. The units of the value programmed under S must be defined by the programmer of the logic (normally the surface speed is expressed in m/min or feet/min but for grinders also m/s and feet/s are used). If G97 is active, the spindle must be programmed in RPM. If G96 is active the programming of S is expressed as a peripheral speed in feet/min (constant surface speed)

The S word is a floating point number (double precision) with a programming format of "6.3", i.e. the number may have up to 6 significant digits before the decimal point and up to 3 significant digits after the decimal point. In this way the 10 Series CNC is able to support all kinds of spindles from large reaming heads up to high frequency spindles.

Rack of S functions

When an S function is programmed the variable “Notify S function” is set to 1 while the data concerning the speed is stored in the S Rack..

The logic must manage the associated value and send an acknowledgement to the system when the execution has been completed. The S function Rack is enabled by setting the appropriate variable of the configuration Rack. The input/output variables of this Rack are

INPUT VARIABLES:

MD(L+17) S function value as programmed (double) MD(L+18) SSL spindle speed limit value (double) MD(L+19) - In G96 mode:

S function value in the active measuring unit (mm or inch)

- In G97 mode: S function value as programmed (rpm)

MD(K+30) Spindle control G code 0 = G97 1 = G96 (short)

OUTPUT VARIABLES:

MD(K+29) task return value (short)

To send the answer “acknowledge function S” to the system it is necessary to insert the following call in the user’s logic:

10 Series CNC WinPLUS Application Manual (04) 5-29

Chapter 5

Logic system communication

The value of MD(L+19) can be used directly as an input parameter in functions: SG96RPM or SG97RPM. With SG96RPM it is normally assumed that S is programmed in m/min (G71) or Feed/min (G70). Should other measure units be used such as Feed/s or m/sec, the appropriate conversions must be made in the logic program starting from the programmed speed value MD(L+17).

Handling the percentage spindle speed override (SS0) is one of the machine logic tasks. Two methods are available to the logic user for handling these variations (for example, after the relevant softkeys are pressed): check any variation recorded in the value of variable S_nSS0 (SW37) by comparing the current value with the previously stored one

In both cases, the value of SS0 is given by the value, multiplied by 100.

After the execution of an S function, the logic must send an acknowledgement to the system. In case of a reset during the execution of this routine, the acknowledgement should be given immediately. What happens to the spindle in case of a reset depends on the type of application.

T FUNCTION

The T part program function is used to transfer up to two values to the logic. The first value is the tool identification code, a positive integer number of up to 12 digits, which is handled using the "double" format. The second value is the tool offset number. This is a positive integer number with a "short" format. Its range is 0..300. Values, tool identification and offset number must be separated by a point "." character when using the T code in the part program.

The programming format for the T word is therefore

Txxxxxxxxxxxx.yyy

The tool identification code is used to determine the tool table page where the required data can be found. Page identification can be done in two ways:

• programmed tool identifier corresponds to the page number (T250)

• tool identifier is a value that allows correct page to be found

The following descriptions are valid for both cases except for the tool table search that is valid only for the second case.

It is possible to express 6 types of T function representation, each with a different meaning.

T xxxxxxxxxxxx (only tool id code xxxxxxxxxxxx)

Insert a new tool. The logic has to search in the tool table for the programmed tool id. Once it has found the page that contains the tool, it must read the tool offset number (TOLOFNR) from the same page, change the tool and activate the offset. Normally a tool change M code is used in the part program (typically M06) to physically execute the tool change and to activate the offset.

T .yyy or T 0.yyy (only tool offset number yyy)

Activate a new tool offset for the actual tool in the spindle. The logic uses the tool offset number as a pointer to the tool offset table.

Chapter 5

Logic System Communication

The logic has to set the tool offset to a zero value. The tool must be removed from the spindle.

T function Rack

The data of the “T function” Rack is updated every time a T function is encountered in a part program block. When this happens the variable “emitted T function” is set to 1 while the data associated with the tool is stored in the other input variables. The logic must manage the parameters that are present in the Rack. The “T function” Rack is enabled by setting the appropriate variable in the configuration Rack.

The input and output variables of this Rack are:

INPUT VARIABLES:

MW(K+32) Tool control word (short) MW(K+33) Tool offset number (short) MW(K+34) Number of axes for offset (1-2) (short) MW(K+35) identifier of first axis (short) MW(K+36) identifier of second axis (short) MW(K+37) Slave tool number (short) MD(L+20) Tool identification code (double) MD(L+21) reserved (double) MD(L+22) cosine for first axis' offset (double) MD(L+23) cosine for second axis' offset (double)

Logic system communication

To send the answer “accept T function” to the system it is necessary to insert the following call in the user’s logic:

Description:

The tool control word MW(K+32) tells your logic how it should handle the information from the MW variables. Twelve programming modes are available, 6 monotool type and 6 multitool. The possible values for the control word in monotool mode are:

1 - T (tool identifier) change tool/offset from table

2 - T (tool identifier).(offset number) change tool but use specified offset

3 - T (tool identifier).0 change tool but no offset

4 - T .0 remove tool offset

5 - T 0 or T 0.0 remove tool and offset

6 - T .(offset number) or

T 0.(offset number) leave tool but change offset

Refer to Fig. 5.24, which shows how these cases are managed by the system.

The values for the control word in multitool mode range from 11 to 16. The essential difference between the two programming types is that in multitool mode the value of control word MW(K+37) is the number of slave tools specified in the T function.

The variable XW 04 contains the number of the offset (= page number of the tool offset table) which has to be applied or a zero value if no offset was programmed.

The variable MW(K+33) contains the offset number (corresponding to the page number of the tool’s offset) that must be applyed, or an 0 value, if no offset has been programmed.

MW(K+33) has no meaning in case 1.

MW(K+34) tells the logic program whether the offset has to be applied to one or two axes. The identifiers of the axes are supplied in MW(K+35) and MW(K+36).

The value of MW(K+37) can be used in multitool programming with the TOOL_RD F. B. required for reading the value of the slave tools programmed in the T function.

The variable MD(L+20) contains the tool identification code as programmed in the active part program block. This code is a number of up to 12 digits, which must be used in conjunction with the function TBLSRCD to find the page of the tool table containing this tool's data.

Logic System Communication

The variables MD(L+22) and MD(L+23) finally pass a cosine value for each one of the axes involved in the tool offset. This cosine value has to be multiplied with the tool length offset for that axis as read from the tool offset table. The 1.0 and 2.0 versions of the control support only 2 values, either 1.0 or -1.0. If you want to use the standard offset handling, you have to pass these two cosine values to the function TOOLACT .

END OF BLOCK RACK

The end of block Rack (EOB) is enabled by setting the appropriate variable in the configuration Rack. When it is active, the EOB management will be called at the end of each motion block, after the last postlude M code. This function is the last opportunity for the logic program to prevent the execution of the following part program block and offers the possibility of changing the system mode of operation.

The application of this routine is for tool status and tool life monitoring where the logic can automatically create a block calculation stop when it needs to change a broken or worn tool with an equivalent sister tool.

To enable the End of Block call, the logic must notify the system using the system function call PREC_OFF. In case of point-to-point, while in addition with G27 or G28 execution the # character must also be put in the block where the end of execution calculation is to be stopped In the EOB routine the logic can check the prerequisites for part program continuation and send an answer to the system (proceed with next block / stop program execution).

The input and output variables of this Rack are:

INPUT VARIABLES:

None

OUTPUT VARIABLES:

MW(K+98) MW(K+98)= 0 The system will proceed with the execution of the next block

MW(K+98) = -1 The part program execution is stopped. The system goes into

"MAS +IDLE" status.

When the system is in "MAS + IDLE" status, the logic can send new values for tools offset via ACTOFFS function.

In order to exit the "MAS" status the logic must activate the PPRESUME function.

To send the answer “accept EOB function” to the system it is necessary to insert the following call in the user’s logic:
