CNC_RDSVMETER | POSITION

Description

Declaration

Arguments

typedef struct odbsvload {
    LOADELM     svload;     /* servo load meter data */
} ODBSVLOAD ;

typedef struct loadelm {
    long    data;    /* load meter data */
    short   dec;     /* place of decimal point */
    short   unit;    /* unit */
    char    name;    /* axis name */
    char    suff1;   /* subscript of axis name 1 */
    char    suff2;   /* subscript of axis 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

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 all servo load meter data, and displays them.

#include "fwlib32.h"

void example( void )
{
        ODBSVLOAD sv[MAX_AXIS];
        short num = MAX_AXIS;
        short ret = cnc_rdsvmeter(h, &num, sv);
        if(!ret) {
                int i;
                for(i = 0 ; i < num ; i++) {
                        printf("%c = %d\n", sv[i].svload.name, sv[i].svload.data);
                }
        }
}
 

Example(C#)

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

class example
{
    public void sample()
    {
            Focas1.LOADELM sv = new Focas1.LOADELM();
            short num = Focas1.MAX_AXIS;

            byte[] bytes = new byte[Marshal.SizeOf(sv) * Focas1.MAX_AXIS];
            IntPtr ptrWork = Marshal.AllocCoTaskMem(Marshal.SizeOf(sv));

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