CNC_RDBTOFSR | NCDATA

Description

Reads the tool offset value for B axis specified by "s_number", "e_number", "type". The offset value is stored in "IODBBTO" with signed binary format.

The unit of offset value is the same as cnc_rdtofs function. See the description of cnc_rdtofs function.

Declaration

#include "fwlib32.h"

FWLIBAPI short WINAPI cnc_rdbtofsr(unsigned short FlibHndl, short s_number, short type, short e_number, short length, IODBBTO *btofsr);

Arguments

FlibHndl   [ in ]

Specify the library handle. See "Library handle" for details.

s_number   [ in ]

Specify the start tool offset number. The available number is 1,...,9.

'This number + aux. function number which can be got by cnc_rdbtofsinfo function + 1' means the tool offset number for B axis which is used by NC command or display.

e_number   [ in ]

Specify the end tool offset number. The available number is 1,...,9.

type   [ in ]

Specify the tool offset type.(see the following table)

length   [ in ]

Specify the data block length.

The combinations of the value specified in "type", the data block length "length", the kind of offset value to be read and the member where the result is stored are as follows.

  • Tool offset Memory A
  • type length Attribute Offset type Member to be stored in
    0 8+4*N individual Tool offset btofsr.ofs[i]
    -1 8+4*N all Tool offset btofsr.ofs[i]

  • Tool offset Memory B
  • type length Attribute Offset type Member to be stored in
    0 8+4*N individual Tool geometry offset btofsr.ofs[i]
    1 8+4*N individual Tool wear offset btofsr.ofs[i]
    -2 8+8*N all Tool geometry offset btofsr.ofs[8*i+0]
    Tool wear offset btofsr.ofs[8*i+4]

    is number of offset to be read, i = 0,..,(N-1).
btofsr   [ out ]

Pointer to the IODBBTO structure including the tool offset value. The IODBBTO structure is as follows.

typedef struct iodbbto {
    short datano_s;             /* start offset number */
    short type;                 /* offset type */
    short datano_e;             /* end offset number */
    long  ofs[M];               /* offset value */
} IODBBTO ; /* M : M is number of the offset value.(Individual, Memory A all)
                   M is number of the offset value * 2.(Memory B all) */

Return

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

The major error codes are as follows.

CNC option

This function need the following CNC option.

    The B axis control function is necessary.

And this function is related to the following CNC option.

  • Series 16/18, 16i/18i/21i

  • Tool geometry/wear compensation

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, 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.
