	CNC_RDDIAG_EXT | MISC Top Description Reads the random number diagnosis data. The diagnosis data numbers are specified by the array of long type ("prm_no[]"). And the number of the array is specified by "num". The information of diagnosis data is stored to the array of IODBPRM structure. If an invalid diagnosis data number is specified, the type field of the IODBPRM structure is -1. In case of non-axis type diagnosis data, the diagnosis data value is stored to the data[0] of the IODBPRM structure. And, in case of axis-type diagnosis data, the diagnosis data value is stored to the data array of the structure. All diagnosis data values are stored to long type. So your application have to cast them according to the type information. See the "MAINTENANCE MANUAL" of CNC for details of each diagnosis data. MTConnect Fanuc Adapter Universal Fanuc Driver Fanuc Focas Library CD Declaration #include "fwlib32.h" or "fwlib64.h" FWLIBAPI short WINAPI cnc_rddiag_ext(unsigned short FlibHndl, long *prm_no, short num, IODBPRM *param); Arguments FlibHndl   [ in ] Specify the library handle. See "Library handle" for details. prm_no   [ in ] Specify the pointer to the array of the diagnosis data numbers. See the "MAINTENANCE MANUAL" of CNC about available diagnosis number. It can be got by cnc_rddiagnum function and cnc_rddiaginfo function. num   [ in ] Specify the number of the diagnosis data to be read. param   [ out ] Specify the pointer to the array of IODBPRM structure to store the diagnosis data. The number of array must be equal to "num". The IODBPRM structure is as follows. typedef struct iodbprm { long datano; /* diagnosis data number */ short type; /* type information */ short axis; /* axis information */ short info; /* attribute */ short unit; /* unit */ struct { long prm_val; /* diagnosis data value */ long dec_val; /* place of decimal point */ } data[32]; } IODBPRM; datano diagnosis data number which was read is stored. type Type information of diagnosis data which was read is stored. 0 : byte type 1 : word type 2 : 2-word type 3 : bit type (8 bit) 4 : bit type (1 bit : except Series 15i) 5 : real type (only Series 15i, 30i, 0i-D/F, PMi-A) -1 : invalid diagnosis data axis Axis information of diagnosis data which was read is stored. bit 0 : axis attribute 0 : without axis 1 : with axis bit 1 : spindle data 0 : no spindle 1 : spindle
bit 2,..,15	:	(reserve)

info

Axis information of diagnosis data which was read is stored.

bit 0

:

sign

0	:	with sign
1	:	without sign

bit 1,..,15 : (reserve)

unit

Unit of diagnosis data which was read is stored.

bit 0, 1

:

unit

0	:	without unit
1	:	%
2	:	RPM

bit 2,..,15 : (reserve)

data

Value of diagnosis data which was read is stored.

prm_val	:	Value of diagnosis data
dec_val	:	Place of decimal point (only available for real type)

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 diagnosis data No.300 and No.410, and displays them.
(Series 16i/18i/21i, 0i, Power Mate i)

#include "fwlib32.h"

void example()
{
        IODBPRM prm[2];
        long prmno[2];
        short ret;

        prmno[0] = 300;
        prmno[1] = 410;
        ret = cnc_rddiag_ext( h, prmno, 2, prm ) ;
        if ( !ret ) {
                printf( "No.300:\n" );
                printf( "  1st axis = %d\n", prm[0].data[0].prm_val );
                printf( "  2nd axis = %d\n", prm[0].data[1].prm_val );
                printf( "  3rd axis = %d\n", prm[0].data[2].prm_val );

                printf( "No.410: = %d\n", prm[1].data[0].prm_val );
        }
