19.8 SysLibFile, SysLibDir, SysLibFileAsync
The file system can be accessed in CoDeSys using the following CoDeSys
libraries: SysLibFile, SysLibDir, and SysLibFile_Async
The following directories can be used for this:
1. Memory on the boot medium: home/codesys/
2. Memory on a CF card/USB flash drive formatted using FAT:
media/<partitionname>/
3. Volatile memory (RAM disk): tmp/
Example:
h_file:=SysFileOpen(media/USBNAME1/data.log', 'a');
The partition name of CF cards/USB flash drives can be assigned using the
WBM/Configtool during formatting. (see chapter “Configuration via Web-Based
Management (WBM)”).
In addition, the CF card/USB flash drive can also be formatted with a different
operating system. The partition name can also be assigned then.
Example using WinXP:
