CNC_SDTREADSMPL2 | MOTOR

Description

Reads the sampling data.
In case of using cnc_sdtstartsmpl2, acquire data immediately after the function call by this function. Trigger is judged by trg?0.

MTConnect Fanuc Adapter

Universal Fanuc Driver

Fanuc Focas Library CD

Declaration

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

FWLIBAPI short WINAPI cnc_sdtreadsmpl2(unsigned short FlibHndl, unsigned short *trg,long datanum, ODBSD *sampledata);

Arguments

FlibHndl   [ in ]

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

trg   [ out ]

Specify the pointer to the variable to store specified trigger condition by cnc_sdtstartsmpl2. Form of trigger condition is as follows.

trigger condition

SEQ:sequence number set to trigger is executed
P_UP:the signal set to trigger rose up
P_DW:the signal set to trigger rose down
STSM:sampling information(0:under sampling, 1:end of sampling)

?change only trigger specified by cnc_sdtstartsmpl2.

datanum   [ in ]

Specify the number of sampling data which you want to read. (Specify the value of eight or more.)
Reading process is executed every 8WORD unit. So, specify the multiple of eight as much as possible for this value.

sampledata   [ out ]

Specify the pointer to the array of ODBSD structure to store the sampling data. The sampling data is acquired in order of channel which was setted by cnc_sdtsetchnl2 function.

The structure of ODBSD is as follows.

typedef struct odbsd {
    unsigned short  *chadata;   /* Pointer to sampling data */
    long            *count;     /* Pointer to reading number */
} ODBSD;

Prepare the buffer area for the sampling data and the area for the number of actually read data.
And the each pointer is set to ODBSD structure. Prepare ODBSD structures of the same number of channels as array. And specify the top pointer of this array to this argument.
After the function is executed normally, the actual number of reading data in each channel is acquired in *count.
In case of trg?0, information at trigger is the last aquired data.

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_BUFFER
(10)
Read buffer is full.
The inner buffer for reading becomes full, so the processing was canceled.
EW_REJECT
(13)
CNC execution denied
In order to get more information for this err_no return value, execute cnc_getdtailerr function.
1:Sampling start function(cnc_sdtstartsmpl2) is not executed.

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

CNC 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 0i-D/F, Series 30i and PMi-A, 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.
