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

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

4+(byte size of setting data)*(number of axis)

In case that the size of setting data is 4 byte, the IODBPSD structure is as follows. In case that its size is 1, 2, or 8 byte, the size of data part per 1 setting data or 1 axis is 1, 2, or 8 byte.

IODBPSD

no axis/1 axis	all axes

• Series 15/15i, 30i, 0i-D/F, PMi-A

n = Maximum controlled axes

• Series 16/18/21, 16i/18i/21i, 0i-A/B/C, Power Mate i

n = Current 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 IODBPSD structure including the setting data. The IODBPSD structure is as follows.

Series 15, 16/18/21, 16i/18i/21i, 0i-A/B and Power Mate i

} IODBPSD ;               /* MAX_AXIS : max. controlled axes */

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.

• Series 15, 16/18/21, 16i/18i/21i, 0i, 30i, Power Mate i, PMi-A
Specify the axis number.

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



• Series 15i
Upper byte:type

0	:	bit type
1	:	byte type
2	:	word type
3	:	2-word type
4	:	real type

Lower byte:axis

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