Description

Declaration

Arguments

typedef struct odbnc {
     union {
        struct {
             short   reg_prg ;   /* Number of registered programs. */
             short   unreg_prg ; /* Number of available programs. */
             long    used_mem ;  /* Character number of used memory. */
             long    unused_mem ;/* Character number of unused memory. */
        } bin ;
        char asc[31] ;           /* Buffer for ASCII format */
     } u ;
} ODBNC ;

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 the management data of NC program, and displays them.

#include "fwlib32.h"

void example( void )
{
        ODBNC buf ;
        short ret ;
        ret = cnc_rdproginfo( h, 0, 16, &buf ) ;
        if ( ret )
                printf( "ERROR: %d\n", ret ) ;
        else {
                printf( "Registered program number   = %d\n",
                        buf.u.bin.reg_prg ) ;
                printf( "Registerable program number = %d\n",
                        buf.u.bin.unreg_prg ) ;
                printf( "Used memory                 = %ld\n",
                        buf.u.bin.used_mem ) ;
                printf( "Free memory                 = %ld\n",
                        buf.u.bin.unused_mem ) ;
        }
}

Example(C#)

The following program reads the management data of NC program, and displays them.

class example
{
    public void sample()
    {
            Focas1.ODBNC_1 buf = new Focas1.ODBNC_1();
            short ret;
            ret = Focas1.cnc_rdproginfo(h, 0, 16, buf);
            if (ret != Focas1.EW_OK)
            {
                    Console.WriteLine("ERROR: {0}", ret);
            }
            else
            {
                    Console.WriteLine("Registered program number   = {0}",
                            buf.reg_prg);
                    Console.WriteLine("Registerable program number = {0}",
                            buf.unreg_prg);
                    Console.WriteLine("Used memory                 = {0}",
                            buf.used_mem);
                    Console.WriteLine("Free memory                 = {0}",
                            buf.unused_mem);
