* ( ) : Basic

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 related to the following CNC parameter.
See the manual of CNC parameter for details.

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 writes all tool offset values of Machining-Series
(Memory A/64 sets).

#include "fwlib32.h"
#define MAXTOOL 64

/* offset is array of new offset value. */
short example( long *offset )
{
    IODBTO *tofsr ;
    short ret ;
    tofsr = (IODBTO *)malloc( 8+4*MAXTOOL ) ;
    tofsr->datano_s = 1 ;
    tofsr->datano_e = MAXTOOL ;
    tofsr->type = -1 ;
    memcpy( &(tofsr->u.m_ofs_a[0]), offset, 4*MAXTOOL ) ;
    ret = cnc_wrtofsr( h, 8+4*MAXTOOL, tofsr ) ;
    free( tofsr ) ;
    return ( ret ) ;
}

Example(C#)

The following program writes all tool offset values of Machining-Series
(Memory A/64 sets).

class example

    public const short MAXTOOL = 64;
    
    /* offset is array of new offset value. */
    public short sample(int[] offset)
    {
        Focas1.IODBTO_1_1 fsrHead = new Focas1.IODBTO_1_1();
