Reads the F-ROM data from CNC.
After F-ROM data reading, execute cnc_fromgetend function in order to indicate the termination of reading process.
The procedure for reading F-ROM data and storing into the file is as follows.
Any file name can be specified for the file in which F-ROM data will be stored.
Internal 128KB buffer is prepared for data reading.
In this function, the F-ROM data is read from CNC every 128 Kbyte block and then the data is output to the application.
It takes for a while to read the 128 Kbyte block of F-ROM data from CNC.
This function waits its process completion in the library.
The total size which can be read finally is F-ROM size(fromsize) acquired by the cnc_getfrominfo function.

Specify the library handle. See "Library handle" for details.
Specify the address of the variable in which the reading state of F-ROM is stored.
|0||:||End of reading process|
|1||:||Reading process continued|
Call the cnc_fromgetend function in case of stat=0.
Pointer to the variable to which the reading data is stored.
Specify the pointer of the variable to which the F-ROM data is stored.
Pointer to the variable to which the data length was set.
(Please set the value of 256 or more in the variable.)
Specify the size in byte which you want to read to the variable. After executing this function, the size of data which was actually read is set.
The maximum size which can be read at a time is F-ROM size (fromsize) acquired by the cnc_getfrominfo function.
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|
Retry because the buffer is empty.
In order to get more information for this err_no return value, execute cnc_getdtailerr function.
The following detail status will be set onto the member, err_no of ODBERR structure.
As for the other return codes or the details, see "Return status of Data window function"
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, the required CNC option is as follows. When Embedded Ethernet is used,
above two optional functions are not required.
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,
When Ethernet board is used,
- only Ethernet function is required.
This function is not related to CNC parameter.
This function can be used in any CNC mode.
