FUNCTION_BLOCK Delete EXTENDS CBM.ETrig
This function block deletes a file.
Contrary to the original CAA specification the file may be deleted even if it is opened via ”FILE.Open”.
This behavior is dependent of the underlying operating system and file system.

BOOL
|
Rising edge: Action starts
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) are present at the outputs for exactly one cycle.
