Description

Declaration

Arguments

typedef struct odbspload {
    LOADELM     spload;     /* spindle load meter data */
    LOADELM     spspeed;    /* spindle motor data */
} ODBSPLOAD ;

typedef struct loadelm {
    long    data;       /* load meter data, motor speed */
    short   dec;        /* place of decimal point */
    short   unit;       /* unit */
    char    name;       /* spindle name */
    char    suff1;      /* subscript of spindle name 1 */
    char    suff2;      /* subscript of spindle name 2 */
    char    reserve;    /* */
} LOADELM;

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

And this function is related to the following CNC option.

This function is related to the spindle switching control.

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.

5845, 5846 (influenced by setting)

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 all spindle load meter, and displays them.

#include "fwlib32.h"

void example( void )
{
    ODBSPLOAD sp[4];   /* 4 = maximum spinlde number */
    short num = 4;
    short ret = cnc_rdspmeter(h, 0, &num, sp);

    if(!ret) {
        int i;
        for(i = 0 ; i < num ; i++) {
            printf("%c%c = %d\n", 
            sp[i].spload.name, sp[i].spload.suff1,
            sp[i].spload.data);
        }
    }
}
 

Example(C#)

The following program reads all spindle load meter, and displays them.

class example
{
    public void sample()
    {
        Focas1.ODBSPLOAD_data sp = new Focas1.ODBSPLOAD_data();
        short num = 4;                                              /* 4 = maximum spinlde number */

        byte[] bytes = new byte[Marshal.SizeOf(sp) * 4];
        IntPtr ptrWork = Marshal.AllocCoTaskMem(Marshal.SizeOf(sp));

        short ret = Focas1.cnc_rdspmeter(h, 0, ref num, bytes);
        if (ret == Focas1.EW_OK)
        {
            int i;
            for (i = 0; i < num; i++)
            {
                Marshal.Copy(bytes, i * Marshal.SizeOf(sp), ptrWork, Marshal.SizeOf(sp));
                Marshal.PtrToStructure(ptrWork, sp);
                Console.WriteLine("{0}{1} = {2}",
                (char)sp.spload.name, (char)sp.spload.suff1, sp.spload.data);
            }
        }
        Marshal.FreeCoTaskMem(ptrWork);
    }
