Description

Reads specified number of M code group data starting from the specified number.

MTConnect Fanuc Adapter

Universal Fanuc Driver

Fanuc Focas Library CD

Declaration

#include "fwlib32.h" or "fwlib64.h"

FWLIBAPI short WINAPI cnc_rdmgrpdata(unsigned short FlibHndl, short s_no, short *num, ODBMGRP *buf);

Arguments

FlibHndl   [ in ]

Specify the library handle. See "Library handle" for details.

s_no   [ in ]

Specify starting number from which the data is read. Valid range is from 0 to 499.

num   [ in / out ]

Pointer to the number of data to be read. Specify the number of data to be read before function call and actual number of data being read is stored after the function call. Valid range is from 1 to 500.

buf   [ out ]

Pointer to the ODBMGRP structure where returned data are stored. The ODBMGRP structure is as follows.


typedef struct odbmgrp {
    long    m_code;
    short   grp_no;
    char    m_name[21];
    char    dummy;
} ODBMGRP;
m_code
M code
M code is returned.
* In case of Series 16/18 and 16i/18i, -1 is returned when no M code is assigned to the number.

grp_no
M code group number
M code group number is returned.

m_name
M code name
M code name is returned.
ASCII character string (maximum 20 characters) with trailing NULL code is stored.
* Not used in case of Series 16/18 and 16i/18i.

Return

EW_OK is returned on successful completion, otherwise any value except EW_OK is returned.

The major error codes are as follows.

Return code Meaning/Error handling
EW_LENGTH
(2)
Data block length error
The number indication(num) is wrong.
EW_NUMBER
(3)
Data number error
The start number(s_no) is wrong.
EW_NOOPT
(6)
No option
The M code group option and the extended driver/library function are necessary.

As for the other return codes or the details, see "Return status of Data window function"

CNC option

This function need the following CNC option.

    This function needs the M code group 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-B, 0i-F and 30i, 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.
