CNC_DIAGNOSS | MISC

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

Specify the diagnosis number.

See the "MAINTENANCE MANUAL" of CNC about available diagnosis data number. It can be got by cnc_rddiagnum function and cnc_rddiaginfo function.

Specify the axis number.

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

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

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

no axis/1 axis	all axes

Pointer to the ODBDGN structure including the diagnosis data.

datano

diagnosis data number which was read is stored.

type

Attribute of diagnosis data which was read is stored.

Upper byte:type (Series 15/15i)

0	:	byte type
1	:	word type
2	:	2-word type
3	:	bit type (8 bit)
4	:	not used
5	:	real type (Series 15i)

Lower byte:axis

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

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

Real diagnosis data is stored.

The value of variable is stored in dgn_val, and the number of places of decimals is stored in dec_val.

Real diagnosis data = dgn_val * 10 ** (-dec_val)

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

dgn_val = 12345
dec_val = 3
