Pointer to the ODBWVDT structure including the waveform diagnosis data.
The ODBWVDT structure is as follows.

typedef struct odbwvdt {
    short   channel ;   /* channel number */

channel

channel number

The channel number which has been read actually is set.

kind

kind of waveform data

Refer to the kind of waveform data in cnc_rdwaveprm function.

• In case that "kind" is except 13(machine signal)

axis

axis number of waveform data( Series 15/15i )

axis number of waveform data
0,..,7	1 to number of controlled axis : axis number
9	1 to number of path : path number
10,..,11	1 to number of spindle : spindle number

axis number of waveform data( Series 16/18, 16i/18i/21i, 0i )

channel number	kind of waveform data
0,..,5		1,..,number of controlled axis : axis number
6, 7	0,..,3, 5,..,7	1,..number of controlled axis : axis number
6, 7	10, 11	1,..number of spindle : spindle number



• In case that "kind" is 13(machine signal)

adr

kind of PMC address of machine signal

The kind of the PMC address which is traced is stored with ASCII code.

kind of PMC address to be set : G, F, Y, X

bit

bit number of machine signal

The bit number of PMC address which is traced is stored.

range of bit number which is stored : 0,..,7

no

number of PMC address of machine signal

The PMC address number which is traced is stored.

The range of stored number is shown in pmc_rdpmcrng

year, month, day, hour, minute, second

If condition is 0,..,20, these are the date when sampling is started.

If condition is 100,..,120, these are the date when sampling is stopped.

year	Year (0,..,99)
month	Month (1,..,12)
day	Day (1,..,31)
hour	Hour (0,..,23)
minute	Minute (0,..,59)
second	Second (0,..,59)

t_cycle

sampling cycle (msec)

MODE	Series 16/18, 16i/18i/21i, 0i		Series 15		Series 15i
condition	0/1/2	100/101/102	0/1/2	100/101/102	kind is except 13	kind is 13
cycle	2	8	2/4/8/16	8	2/4/8/16	8/16

data

waveform diagnosis data

The data which is specified by "kind" is stored.(In case of kind=13, this is 0/1. Othewise, this is binary data)

Concerning the unit, etc., refer to the kind of the waveform data in cnc_rdwaveprm function.
