17.13 Filenames used with the Removable Media (RM) Function Blocks
The RM function blocks support the flash with a DOS/Windows standard FAT-16 file system. All
names must be limited to the “8.3” format where the filename contains eight characters a
period then a three-character extension. The entire filename including any path must be less
than or equal to 147 characters.
When creating filenames and directories it is sometimes desirable to include parts of the current
date or time. There are six special symbols that can be entered into a filename that are replaced
by the OCS with current time and date information.
