CNC_RDOMHISTRY2 | HISTORY

Description

Reads the external operator's message history data. Please use this function for Series 30i, 0i-D/F and PMi-A.

The unit of one external operator's message 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 message history data is acquired in old order.

Declaration

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

FWLIBAPI short WINAPI cnc_rdomhistry2(unsigned short FlibHndl, unsigned short s_no,unsigned short e_no, unsigned short length,ODBOMHIS2 *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 ODBOMHIS2 structure)


his   [ out ]

Pointer to the ODBOMHIS2 structure in which the alarm history data is stored. The ODBOMHIS2 structure is as follows.

        char    ope_msg[256];   /* operator's message        */
    } opm_his[N];               /* N : number of external operator's 
                                       message history data to be read */
} ODBOMHIS2;

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 ODBOMHIS2 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.
EW_NOOPT
(6)
No option
The external message option or the external data input option, and the extended driver/ library function are necessary.
EW_PARAM
(9)
CNC parameter error
CNC parameter '3112#2' must be 1.

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