Configuring Removable Media Manager graphical object in Cscape
The Removable Media Manager is a graphical object that allows viewing filenames, size and dates of
files, and directories on a CompactFlash card. The operator can optionally change directories, delete
files, and format new flash cards. This object also supplies status information such as Color change on
card OK, Card full, and Card missing status. For additional information, refer to Cscape Help File;
select Cscape Reference Manual, and then select Using Graphics Editor.

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 “eight dot three” 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 QX751
with current time and date information.
Table 6.1 – 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
$s Substitutes the current minute
Note that all the symbols start with the dollar sign ($) 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
