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

Specify the data block length which is enough to store the specified setting data.

The structure per 1 setting data is as follows, and each setting data must be lined up in order of number.

[= Sum of (4+(byte size of each setting data) *(number of axis))]

In case that the size of setting data is 2 byte, the IODBPSD structure is as follows. In case that the size of setting data is 1 or 2 byte and the length per 1 setting data is not a multiple of 4, 'dummy' is necessary in the end of structure. In case that its size is 4 or 8 byte, the size of data part per 1 setting data or 1 axis is 4 or 8 byte, and so 'dummy' is not necessary.

IODBPSD

no axis/1 axis	all axes

n = Maximum controlled axes

In case of Series 15i, 16/18/21, 16i/18i/21i, 0i, 30i, Power Mate i and PMi-A, the spindle setting data has an axis attribute, and the data for number of spindle are valid.

Pointer to the area to store the setting data. Each setting data can be referred by using the IODBPSD structure.

datano

Specify the setting data number.
See the "PARAMETER MANUAL" of CNC about available setting data number. It can be got by cnc_rdsetnum function and cnc_rdsetinfo function.

type

Specify the attribute of setting data.

Upper byte:type

0	:	bit type
1	:	byte type
2	:	word type
3	:	2-word type
4	:	real type(Series 15i, 30i, 0i-D/F, PMi-A)

Lower byte:axis

0	:	assigns no axis
1,..,m	:	assigns 1 axis(m=max. controlled axes)
ALL_AXES	:	assigns all axes(ALL_AXES=-1)

rdata, rdatas ( Series 15i, 30i, 0i-D/F, PMi-A )

Specify the real setting data.
Specify the value of variable in prm_val, and specify the number of places of decimals in dec_val.

Real setting data = prm_val * 10 ** (-dec_val)

(Example) When the value of real setting data is 12.345, prm_val and dec_val are read as follows.

prm_val = 12345
dec_val = 3
