CNC_RDALMHISTRY | HISTORY

Description

Reads the alarm history data. 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".

This function cannot be used for Series 15i, so use cnc_rdalmhistry2 function instead of cnc_rdalmhistry function.

The alarm history data is acquired in old order.

#include "fwlib32.h"

FWLIBAPI short WINAPI cnc_rdalmhistry(unsigned short FlibHndl, unsigned short s_no, unsigned short e_no, unsigned short length, ODBAHIS *his);

Arguments

FlibHndl   [ in ]

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

s_no   [ in ]

Specify the start record number.(more than 1)

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 ODBAHIS structure(length) is wrong.
(e_no-s_no+1) * sizeof(data[0]) + 6 > 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 extended driver/library function is necessary.

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

CNC option

For HSSB connection,

    This function needs the extended driver/library function.

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, 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.
