Ensure that files are saved!
Files are not reliably saved on the data medium until you call up the
“SysFileClose” function block!
Additional information about this is given in the online Help function for
CODESYS-IDE.
Notes on the parameters of the function blocks
File and directory names distinguish between upper and lower case!
“test.txt”≠ “TEST.TXT”≠ “Test.txt”
The separator for directories is: “/.”
The file system supports:
-
Absolute paths, (e.g., “/media/sd/test.txt”)
-
Relative paths (e.g., “testpath/test.txt”)
-
Macros (e.g., “HOME://”, “CARD://”, “TMP://”)
