CNC_RDALMHISTRY4 | HISTORY

Description

Reads the alarm history data.

Please use this function instead of cnc_rdalmhistry for Series 30i.

The unit of one alarm history data is called a record.

The operation history data and the alarm history data are automatically recorded on the CNC. When these data are accessed, it is necessary to temporarily stop sampling on the CNC. Therefore, it is necessary to execute "Stop logging operation history data"(cnc_stopophis) before this function is used.

And it is necessary to execute "Restart logging operation history data" (cnc_startophis) after reading to make the sampling stop time of the history data as short as possible.

The start/end record number means the relative number uesd at reading the alarm history data. These record numbers are valid only at the period from the execution of "Stop logging operation history data" until the execution of "Restart logging operation history data".

The alarm history data is acquired in old order.

Declaration

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

FWLIBAPI short WINAPI cnc_rdalmhistry4(unsigned short FlibHndl, unsigned short s_no, unsigned short e_no, unsigned short length,ODBAHIS4 *his);

Arguments

FlibHndl   [ in ]

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

s_no   [ in ]

Specify the start record number. (specify 1 or more.)

e_no   [ in ]

Specify the end record number. (specify 1 or more.)

length   [ in ]

Specify the data block length. (size of ODBAHIS4 structure)


his   [ out ]

Pointer to the ODBAHIS4 structure in which the alarm history data is stored. The ODBAHIS4 structure is as follows.

typedef struct odbahis4 {

        short   len_msg;        /* Length of alarm message */
        short   pth_no;         /* path number             */
        short   dummy;
        char    alm_msg[64];    /* alarm message           */

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_FUNC
(1)
cnc_stopophis function has not been executed.
EW_LENGTH
(2)
Data block length error
Size of ODBAHIS4 structure(length) is wrong.
(e_no-s_no+1) * sizeof(data[0]) + 4 > length
EW_NUMBER
(3)
Data number error
The specification of the record number (s_no, e_no) is wrong.
