MODE (ENUM) ¶ TYPE MODE : This data type defines mode values for file access to use with the FILE.Open function block. Attributes: qualified_only InOut: Name Initial Comment MWRITE 0 Write access, file will be overwritten or created MREAD Read access, file will only be opened for reading MRDWR Read- and Write access, the file will be overwritten or created MAPPD File will be opened in WRITE mode, but the written data will be appended at the end of the file MREADPLUS Open an existing file with Read/Write access. If file does not exist, Open fails

DirClose (FB; Prefix fildcl) ¶ FUNCTION_BLOCK DirClose EXTENDS CBM.ETrig This function block closes the access on the specified directory. InOut: Scope Name Type Comment Input hDir CAA.HANDLE Directory handle Output eError ERROR Local library error ID (0: no error; 5101: time out)

DirCopy (FB; Prefix fildcp) ¶ FUNCTION_BLOCK DirCopy EXTENDS CBM.ETrig This function block copies the contents of the source directory to the destination directory Nonexisting destination path will be created. Depending of the parameters, all subdirectories and its content will be copied too, and existing files will be overwritten. NOTE: Empty direcories will be copied if xRecursive is TRUE. InOut: Scope Name Type Comment Input sDirNameDest CAA.FILENAME destination directory name sDirNameSource CAA.FILENAME source directory name xRecursive BOOL TRUE: all subdirectories and their contents are copied, FALSE: subdirectories are omitted xOverWrite BOOL TRUE: existing files are overwritten, FALSE: existing files are left untouched Output eError ERROR Local library error ID (0: no error; 5101: time out)

DirCreate (FB; Prefix fildcr) ¶ 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. InOut: Scope Name Type Comment Input sDirName CAA.FILENAME Name of the new directory, absolute or relative path specification xParent BOOL Create missing subdirectories; TRUE: missing sub-directories will be created automatically, FALSE: missing sub- directories will cause an error message Output eError ERROR Local library error ID (5104 - FILE_NOT_EXIST: Directory does not exist; 5105 - FILE_EXIST: Directory already exists )
