■ File Names
■ Directories
There are two media that can be used to store files in memory for CS/CJ-
series PLCs:
Files are distinguished by assigning file names and extensions. The following
characters can be used in file names and extensions:
The following characters cannot be used in files names and extensions:
File names are not case sensitive and will be converted to all-caps in the PLC
file system. File names can be up to 8 character long with 3-character exten-
sions. An error will occur if a file name or extension is too long. The first period
(.) in a file name will be taken as the delimiter between the file name and
extension. Extensions are determined by the file type.
Up to five levels of directories (including root as the first level) can be created
as file storage locations. A maximum of 65 characters can be used in direc-
tory names.
