CNC_RDALMHISTRY2 | HISTORY

Description

Reads the alarm history data. Please use this function instead of cnc_rdalmhistry for Series 15i.

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 unit of one alarm history data is called a record. 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 16/18/21, 16i/18i/21i, 0i and Power Mate i, so use cnc_rdalmhistry function instead of cnc_rdalmhistry function.

FWLIBAPI short WINAPI cnc_rdalmhistry2(unsigned short FlibHndl, unsigned short s_no, unsigned short e_no, unsigned short length, ODBAHIS2 *his);

Arguments

FlibHndl   [ in ]

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

s_no   [ in ]

Specify the start record number.(more than 1)

e_no   [ in ]

Specify the data block length(size of ODBAHIS2 structure).
ODBAHIS2


his   [ out ]

Pointer to the ODBAHIS2 structure in which the alarm history data is stored. The ODBAHIS2 structure is as follows.

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 ODBAHIS2 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 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.
