CNC_RDWAVEDATA | WAVE

Description

Reads waveform diagnosis data.

In case of using this function, the waveform diagnosis screen of CNC must not be used.
If used, the behavior of this function is not guaranteed.

In case that the waveform diagnosis parameter is changed, the correct data cannot be read if cnc_wavestart function is not executed.

EW_NUMBER
(3)
data number error
Channel number(channel) is out of range.
EW_ATTRIB
(4)
data attribute error

EW_DATA
(5)
data error
Start pointer to read(rd_pntr) is out of range.
EW_NOOPT
(6)
no option
The extended driver/library function is necessary.
EW_PARAM
(9)
CNC parameter error( Series 16/18, 16i/18i/21i, 0i )
3112#0=0 when CNC is turned on.
set 3112#0=1 and reboot.
EW_BUFFER
(10)
buffer empty
There is no specified waveform diagnosis data.
(The case that the condition of a waveform diagnosis does not correspond to the specified channel number is included.)

As for the other return codes or the details, see "Return status of Data window function"

CNC option

For HSSB connection,

    The extended driver/library function is necessary.

For Ethernet connection,

    The Ethernet function and the extended driver/library function are necessary.

    However, in case of Series 16i/18i/21i-B, 0i-B/C, the required CNC option is as follows.

    When Embedded Ethernet is used,

      above two optional functions are not required.

    When Ethernet board is used,

      only Ethernet function is required.

CNC parameter

This function is related to the following CNC parameter.
See the manual of CNC parameter for details.

  • Series 16/18, 16i/18i/21i, 0i
