CNC_SDTREADSMPL2 | MOTOR

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

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

trigger condition

?change only trigger specified by cnc_sdtstartsmpl2.

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.

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.
