SysDirAsyncFB.SysDirRenameAsync (METH) ¶ METHOD SysDirRenameAsync : RTS_IEC_HANDLE This method asynchronously renames a directory. For details, see Description. InOut: Scope Name Type Comment Return SysDirRenameAsync RTS_IEC_HANDLE Handle of AsyncJob Input pParam POINTER TO tSysDirRename pudState POINTER TO UDINT Current state of AsyncJob pResult POINTER TO RTS_IEC_RESULT Result of AsyncJob creation

SysDirAsyncFB.SysDirSetCurrentAsync (METH) ¶ METHOD SysDirSetCurrentAsync : RTS_IEC_HANDLE This method asynchronously sets the current working directory on the target. In this directory all following file functions are operated. This setting applies to file access from IEC only. An empty string resets the working directory to its default. This method should not be used in parallel to any other file operation from IEC. For details, see Description.
