Description
Reads various data which changes at CNC operation at a time.
This function is the improved version of the cnc_rddynamic function. Please use this function because the cnc_rddynamic function cannot read all alarm status of Series 15i. The data which can be read is as follows.
| Data | Function used for reading individually |
|---|---|
| Alarm status | cnc_alarm2 |
| Program number in executing | cnc_rdprgnum |
| Program number of the main program | cnc_rdprgnum |
| Sequence number | cnc_rdseqnum |
| Actual feed rate | cnc_actf |
| Actual spindle speed | cnc_acts |
| Absolute position data of controlled axis (2) | cnc_absolute2 |
| Machine position data of controlled axis | cnc_machine |
| Relative position data of controlled axis (2) | cnc_relative2 |
| Amount of distance to go of controlled axis | cnc_distance |
The formats of each data are same as "Function used for reading individually". Refer to each function for details.
The data concerning the axis is read by specified with axis. Each data is stored in oaxis structure in ODBDY2.
All axes can be read at a time by specifying ALL_AXES for "axis". In that case, various data concerning the axis is stored in each array of faxis inside of ODBDY2.
The decimal point position of the various data concerning the axis can be acquired in the cnc_getfigure function.

Return
EW_OK is returned on successful completion, otherwise any value except EW_OK is returned.
The major error codes are as follows.
| Return code | Meaning/Error handling |
|---|---|
(2) |
Size of ODBDY structure(length) is illegal. |
(4) |
The specification of axis number (axis) is improper. |
As for the other return codes or the details, see "Return status of Data window function"
CNC option
For HSSB connection,
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/D/F, Series 30i and PMi-A, 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.
