Libraries > CT File Access > Function Blocks

This function block flushes data from the file system cache to the disk for the file with given file handle hFile. Calling this function block guarantees that data will be stored on the disk.

Falling edge: Resets outputs If a falling edge occurs before the function block has completed its action, the outputs operate in the usual manner and are only reset if either the action is completed or in the event of an error. In this case, the corresponding output values (xDone, xError, iError) are present at the outputs for exactly one cycle.

hFile

CAA.HANDLE

Handle of the directory or the file

xDone	BOOL	Action successfully completed
xBusy	BOOL	Function block active
xError	BOOL	TRUE: error occurred, function block aborts action FALSE: no error
