FUNCTION_BLOCK DirCreate EXTENDS CBM.ETrig
This function block creates a sub-directory in the standard directory. If the sub-directory already exists, an error message is generated. There may be restrictions concerning the specification of the directory name, e.g. only capital letters allowed, for different targets. The function ”FILE.GetProperty” shows these restrictions.

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.
