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

Specify the number of channels which wants to be sampled. Maximum channel numbers are "8".
However, the following limitations are in the data which can be acquired at the same time.

Specify the number of total points of the data which wants to be sampled. (Specify the value of eight or more.)
If you wants to read data after all sampling ends, the maximum number which can be set is as follows.

So, when the sampling data of each 10msec is necessary, the following numbers can be sampled.

In case that data is serially read during the sampling execution, this limitation does not exist.
When -1 is specified, the limitation of a total number is lost.
Please serially read the data by the sampling data reading function(cnc_sdtreadsmpl).
When the reading buffer is filled, the sampling data reading function returns EW_BUFFER.

Pointer to the IDBSFBCHAN structure including the channel data.
Prepare the number of the channel data which you want to set as an array, and specify the top pointer of the array for this argument(channel).

The structure of IDBSFBCHAN is as follows.

                typedef struct idbsdtchan {
                short           type;       /* data type */
                char            chno;       /* channel number */
                char            axis;       /* axis number */
                unsigned short  shift;      /* upper byte : sampling cycle,
                lower byte : right shift amount */
                } IDBSDTCHAN;

Specify the channel number(1-8).

axis

Specify the sampling axis number.

Servo axis number	:	1 to 32
Spindle axis number		-1 to -8

Specify the logical axis number which is allocated to the entire paths of CNC system.

The axis number is not the relative axis number of each path.

(It is the same as the order of CNC parameter No.981(Spindle axis is No.982).)

shift

Specify sampling period at upper byte and right shift value at lower byte.

Specify sampling period at upper byte as follows.

0	:	1msec
2	:	0.25msec

* 0.25msec can be set in case of servo data. In case of setting any value except 0 to shift's upper byte, EW_DATA(5)(No.24 for detail) is returned.

* In case of difference of sampling period of servo between channels, EW_DATA(5)(No.24 for detail) is returned. Make the same sampling period of servo between channels.

* In case of setting under the following conditions simultaneously, EW_DATA(5)(No.3 for detail) is returned.

• 0.25msec(Sampling period of servo)
• 1msec (Sampling period of spindle)
• any normal value except -1(The number of total points of sampling data to read(per one channel), datanum)

In case of setting channel of servo(Sampling period : 0.25msec) and spindle(Sampling period : 1ms) at the same time, set the number of total points which wants to be sampled(per one channel), datanum to -1 and execute process of count the number of reading data and of end of sampling in program.

Specify the right shift amount(0-15) for the sampling data at lower byte.

The sampling data acquired by specifying this data is as follows.

In case of shift = 0	:	1 detection unit(or 1 rotation)
