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.

• Series 15/15i


Program name 48 characters
If this option does not exist, the maximum program name is 16 characters.

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 registration information of NC program,
and displays program number list.

#include "fwlib32.h"

#define BUFSIZE 100

void example()
{
        PRGDIR3 prg[BUFSIZE];
        short i, num;
        long top = 0;
        short ret;

        do {
                num = BUFSIZE;
                ret = cnc_rdprogdir3( h, 0, &top, &num, prg );
                if ( ret == EW_NUMBER ) {
                        break;
                }
                if ( ret ) {
                        printf( "ERROR: %d\n", ret );
                        break;
                }
                for ( i = 0 ; i < num ; i++ ) {
                        printf( "O%d\n", prg[i].number );
                }
                top = prg[num-1].number + 1;
        } while ( num >= BUFSIZE );
}

Example(C#)

The following program reads all registration information of NC program,
and displays program number list.

            short ret;

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