Description
Reads the sequence number of the NC program which is being currently executed in CNC.
If the NC program has no sequence numbers in its all blocks, the sequence number of the last executed block is read.
This function is used for watch the block being executed or the current process by the application program, or only displaying the current sequence number.
The sequence number is stored in "buf.data" with unsigned binary format.
Universal Fanuc Driver
Fanuc Focas Library CD
Declaration
Arguments
Specify the library handle. See "Library handle" for details.
Pointer to the ODBSEQ structure including the sequence number under execution.
The ODBSEQ structure is as follows.
typedef struct odbseq {
short dummy[2] ; /* Not used. */
long data ; /* Sequence number in executing. */
} ODBSEQ ;
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 |
|---|---|
(9) |
7613#0=0 when CNC is turned on. Set CNC parameter again. |
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.
CNC mode
This function can be used in any CNC mode.
