10 Series CNC WinPLUS Library - User Manual

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 Structured Text (ST) 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 WinPLUS, its language and its applications in the 10 Series CNC environment consult the following manuals:

10 Series CNC WinPLUS APPLICATION MANUAL	Code 45006926D
10 Series CNC WinPLUS development tool	Code 45006877B

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 the Structured Text (ST). All the other function blocks are extensions which internally use a function call. These functions can also be used in the ST editor. For each FB there is an example for the calls and the necessary parameters in ST.

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.

Preface

10 Series CNC WinPLUS Library - User Manual

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. For non OS-Wire systems , 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.

OS-Wire systems are not subjected to any hardware limitation and therefore the number of physical axes may range from 1 to 32, and the same applies to the total number of transducers and converters.

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)

For non OS-Wire systems , 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.

In OS-Wire systems, the identifiers mapped on the bus use code 1nntHex, where ‘nn’ is the address (from 0 to 3DHex) of the device and ‘t’ is the transducer number from 1 to 3. On the OS3 drive you can fit (as an option) only one incremental transducer, on the Bridge you can have up to 3 transducers. D/A converters use a similar system of codes (this applies only to Bridge devices): 2nncHex, where ‘nn’ is the address of the device (from 0 to 3DHex) and ‘c’ is the converter number from 1 to 3.

In OS-Wire systems fitted with local transducers and converters (i.e., not mapped on a digital bus but present on the board connector), the identifier codes are the same as are used in non OS-Wire systems.

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 (WinPLUS). An INTERNAL function call is in all aspects like a subroutine available to the WinPLUS 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.

NC RELATED FUNCTIONS

The NC system function calls allow the WinPLUS logic program to communicate with the system and to request the execution of typical CNC related functions (operator functions, part program related functions). All functions can be used as a function block or can be called as a function in the Structured Text. This chapter gives the type and sequence of parameters for the Structured Text call. Where necessary, the function and its conditions are explained.

Each function has a return value (parameter 'stat_wrd') which can be found in Appendix B ("Messages relative to NC) or a zero value if the execution was completed without errors.

CYCLE: Request cycle for a selected process

Type: Wait

LD/FBD:

stat_wrd

ST:

stat_wrd := CYCLE(proc_num);

INPUT VARIABLE:	process number (1..20)	(int)
OUTPUT VARIABLE:	status word	(int)

Description:

This function is utilized to simulate pressing of the command module's cycle start button from WinPLUS

The WAIT CYCLE function allows synchronization with the NC module and always receives an acknowledge from the process.

On exit from the CYCLE call two situations can take place, according to the process' status:

•	Process in "IDLE" status:	The command that has been sent in execution following the
		CYCLE call is being executed; you must wait for the process
		to enter "IDLE" status so that the command can be executed
•	Process in "RUN" status:	The command sent in execution following the CYCLE call
		has already been executed.

NOTE:

This function can be used, when the logic sends the blocks MDI (MDI_CMD) to execution.

In presence of a CYCLE command, the logic can synchronise with the NC environment as follows:

•execution of a block in MDI with actual axes movements using the routines CONMOV and ENDMOV

•execution of a block in MDI without moving the axes by testing the process signal status IDLE and RUN.

The function CYSTART has the same features as the function CYCLE, but as it is a NOWAIT, it does not allow a proper synchronisation between the logic and the NC environment, if the block sent to execution does not contain an actual axis move.

CYSTOP: Request cycle stop for the selected process

stat_wrd := CYSTOP(proc_num,ax_id);

INPUT VARIABLES:	process number (1..20)	(int)
	axes identifier of axis to be stopped	(int)
OUTPUT VARIABLE:	status word	(int)
Description:
This function stops the axis' motion (ax_id) relative to the		process specified by the user
("proc_num").

The "ax_id" parameter is insignificant, in fact the axis in motion can be stopped without the "ax_id" axis identify;

Despite this we advise to give the identifier of the axis to be stopped to the "ax_id" parameter for reasons of future developments compatibility.

FEEDHLD: Request the interpolator to enter the feedhold status

LD/FBD:

stat_wrd

ST:

stat_wrd := FEEDHLD(proc_num);

INPUT VARIABLE:	process number (1..20)	(int)
OUTPUT VARIABLE:	status word	(int)

Description:

This function simply sets the feedrate to a zero value. Any on-going interpolating axes motion in the selected process is suspended. The motion can be resumed with FEED_GO.

NOTES:

•This function is not executed when the control is working in G33 (thread cutting) or G84 (tapping). The stat_wrd variable contains a corresponding error code.

•The feedhold state is not cancelled by a RESET.

•Flag S_nFEEDH (S 20_15) informs the logic about the actual state of the control.

stat_wrd := FEED_GO(proc_num);

INPUT VARIABLE:	process number 1-20	(int)
OUTPUT VARIABLE:	status word	(int)

Description:

This function makes the interpolator exit the feedhold state requested by the function FEEDHLD. The feedrate with the value previous to the entry in feedhold state is restored. The motion of the axes resumes.

If you call this function when the interpolator is not in feedhold state, nothing happens.

FEEDHEM: request to interpolator to enter in feedhold at end of movement

Type: No Wait

LD/FBD:

stat_wrd

ST:

stat_wrd := FEEDHEM(proc_num);

INPUT VARIABLE :	number of process 1-20	(int)
OUTPUT VARIABILE :	status word	(int)

Description:

With this function the final point of the movement (program block) currently executed is reached at zero speed. At this point feedrate is set on zero as is done with the FEEDHLD function. The movement can be resumed with FEED_GO.

NOTES:

•This function applies continuous motions, as reaching the final point at zero speed is an intrinsic characteristic in all other types of movement and hence the function in question is an integral part of the movement. However, at the end of all types of movement, feedrate is set on zero.

•Stopping at the final point of a movement is not ensured if the stop request is executed at a distance from the final point of the movement which is not sufficient to stop the movement (compatibly with the acceleration values configured on the axes); in this case, the stop will occur on the subsequent movement(s), as in a regular feedHold.

•If the stop at final point has been correctly requested, stop coordinates may differ from the final point of the movement by a distance of the order of 0.01 mm.

•This function is not performed when the control is working in G33 mode (threading) or G84 (tapping). The stat_wrd variable contains the corresponding error code.

•Feedhold status is not deleted by a RESET.

•The S_nFEEDH (S 20_15) flag informs the logic as to the current control status.
