Also, the OCS file system allows multiple concurrent file accessing. For example, an FTP Client
can read a file at the same time the OCS ladder program is logging data to another file. It is also
possible for both the FTP Client and OCS ladder functions to read the same file at the same time.
If there is a file access conflict, such as an FTP Client attempting to delete a file that is currently
being read or written by ladder, the file delete request is denied and an error response is sent to
the FTP Client.
