Additional Configuration
a. Alarms

Alarm data can be logged to a .CSV file stored on Removable Media.
b. Screen Capture

The screen capture function allows a bitmap or jpeg image of the displayed
OCS screen to be written to the Removable Media card.
c. Filename Counters
—
The filename counters can be accessed wherever Removable Media
functions require a path name. A typical application is the auto-incrementing of a file name
when doing screen captures.
d. File Select

File Select is used to specify the register block that is used with the Removable
Media Manager object ‘Write Selected Filename’ option.
17.13 Filenames used with the Removable Media (RM) Function Blocks
The RM function blocks support the flash with a DOS/Windows standard FAT16 file system. All
names must be limited to the “8.3” format where the filename contains eight characte
rs 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.
