Description
Reads the parameter specified by "number","axis"(only for the parameter with axis). The data format depends on each parameter. The format of Byte/Word/2-Word parameter is generally signed binary format. Reads the parameter for all axes once by specifying 'ALL_AXES' in 'axis'. The parameter for each axis is stored in each array of "IODBPSD".
The attribute of CNC parameter depends on the type and axis, and it is different for each parameter. It is as follows, and can be got by cnc_rdparainfo function.
| Parameter type | Meaning | Byte size |
|---|---|---|
| Bit parameter | Every bits have each definition. | 1 |
| Bit parameter with axis | Every bits have each definition. (each axis) | 1 |
| Byte parameter | 1-byte data is stored. | 1 |
| Byte parameter with axis | 1-byte data is stored. (each axis) | 1 |
| Word parameter | 2-byte data is stored. | 2 |
| Word parameter with axis | 2-byte data is stored. (each axis) | 2 |
| 2-Word parameter | 4-byte data is stored. | 4 |
| 2-Word parameter with axis | 4-byte data is stored. (each axis) | 4 |
| Real parameter (only Series 15i, 30i, 0i-D/F, PMi-A) |
4-byte data which indicates value of variable and 4-byte data which indicates number of places of decimals are stored. | 8 |
| Real parameter with axis (only Series 15i, 30i, 0i-D/F, PMi-A) |
4-byte data which indicates value of variable and 4-byte data which indicates number of places of decimals are stored. (each axis) | 8 |
It is impossible to read any bit parameter bit by bit. 8 bits(i.e. 1 byte) which belong to the same parameter number are read at the same time.
See the "PARAMETER MANUAL" of CNC for details of each parameter.

Declaration
Arguments
Specify the library handle. See "Library handle" for details.
Specify the parameter number.
See the "PARAMETER MANUAL" of CNC about available parameter number.
It can be got by cnc_rdparanum function and cnc_rdparainfo function.
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) |
Specify the data block length(size of IODBPSD structure).
(4+(byte size of parameter)*(number of axis))
In case that the size of parameter 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 parameter 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
The spindle parameters have an axis attribute, and the data for number of spindle are valid.
Pointer to the IODBPSD structure including the parameter. The IODBPSD structure is as follows.
Series 15, 16/18/21, 16i/18i/21i, 0i-A/B and Power Mate i
typedef struct iodbpsd {
short datano; /* parameter number */
short type; /* upper byte:type */

} IODBPSD ; /* MAX_AXIS : max. controlled axes */
- datano
- Parameter number which was read is stored.
- type
- Attribute of parameter which was read is stored.
- Upper byte:type(only Series 15/15i)
0 : bit type 1 : byte type 2 : word type 3 : 2-word type 4 : real type (only Series 15i) - 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 )
- Real parameter is stored.
The value of variable is stored in prm_val, and the number of places of decimals is stored in dec_val. -
Real parameter = prm_val * 10 ** (-dec_val)
(Example) When the value of real parameter is 12.345, prm_val and dec_val are read as follows.
prm_val = 12345
dec_val = 3
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 IODBPSD structure(length) is wrong. |
(3) |
Parameter number(number) is wrong. |
(4) |
Axis number(axis) is wrong. |
(17) |
( Series 16i/18i/21i, 0i ) |
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 not related to CNC parameter.
CNC mode
This function can be used in any CNC mode.
