Directory path
The following rules govern the specification of the directory path:
● A "/" is located at the start and end of the directory path and as separator for the individual
path sections.
Note
A double slash ("//") within the directory path is not permitted!
● Directory names:
– Directory names must begin with a letter or a digit. Only for addressing in the NC notation
do directory names begin with the domain identification "_N_".
– The following characters can be any combination of letters, digits and "_".
Note
Spaces in directory names are also permitted for external program memories. This is not
true, however, when the external program memory is created as global part program
memory (GDIR).
– Other special characters are not permitted.
● Directory extensions:
– Directory extensions must consist of three letters/digits.
– They are separated with "_" (NC notation) or "." (EES notation) from the directory name.
Note
The passive file system has only the directory extensions _DIR and _WPD.
