8.3 Configuring Removable Media Manager graphic object in Cscape
The Removable Media Manager is a graphic object that allows viewing filenames, size and dates of files,
and directories on a RM card. The operator can optionally change directories, delete files, and format new
RM cards.This object also supplies status information such as Color change on card OK, Card full, and
Card missing status. For additional information, refer Cscape Help File|Graphics|Removable Media.

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.
Table 8.1 – Filename Special Symbols
Symbol Description Example
$Y Substitutes the current 2 digit year 2004 = 04
$M Substitutes the current month with a 2 digit code March = 03
$D Substitutes the current day 22
nd
= 22
$h Substitutes the current hour in 24 hour format 4 pm = 16
$m Substitutes the current minute 45 = 45
$s Substitutes the current second 34 = 34
Note that all the symbols start with the dollar sign ($) character. Date symbols are in upper case, time
symbols are in lower case. The following are examples of the substituted time/date filenames:
Current date and time: March 1, 2004 3:45:34 PM
Filename: Data$M$D.csv = Data0301.csv
Filename: Year$Y\Month$M\aa$D_$h.csv = Year04\Month03\aa01_15.csv
Filename: Month_$M\Day_$D\$h_$m_$s.csv = Month_03\Day_01\15_45_34.csv
