CNC_RDMOVRLAP | POSITION

Description

Declaration

Arguments

Specify the length of the data block(size of IODBOVL structure)

IODBOVL

n = Maximum controlled axes
(The data for current controlled axes are valid.)

typedef struct iodbovl {
    short   datano;                 /* Not used. */
    short   type;                   /* Axis number. */
    long    data[2][MAX_AXIS];      /* Manual overlapped motion value. */
} IODBOVL ;                    /* MAX_AXIS is the maximum controlled axes. */

Return

EW_OK is returned on successful completion, otherwise any value except EW_OK is returned.

The major error codes are as follows.

As for the other return codes or the details, see "Return status of Data window function"

CNC option

This function need the following CNC option.

The handle interrupt function are necessary.

For HSSB connection,

The extended driver/library function is necessary.

For Ethernet connection,

The Ethernet function and the extended driver/library function are necessary.

However, in case of Series 16i/18i/21i-B, 0i-B/C/D/F, Series 30i and PMi-A, the required CNC option is as follows.

When Embedded Ethernet is used,

above two optional functions are not required.

When Ethernet board is used,

only Ethernet function is required.

CNC parameter

This function is not related to CNC parameter.

CNC mode

This function can be used in any CNC mode.

Available CNC

Note) 0i-C does not support the HSSB function.

Example(C Language)

The following program reads the manual overlapped motion value for all axes
and displays them. (in case of "mm input" and "IS-C".)

#include "fwlib32.h"

    double  double_val ;
    IODBOV  movrlap ;
    short   ret ;
    short   i ;

    ret = cnc_rdmovrlap(h, ALL_AXES, 4+4*2*MAX_AXIS, &movrlap);

    for ( i = 0 ; i < MAX_AXIS ; i++ ) {
        double_val = (double)movrlap.data[i]/10000 ;
        printf("axis[%d]:%8.4f\n", i, double_val);
    }
