13.7 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 I3N with
current time and date information.
Table 13.2 – Filename Special Symbols
Symbol Description Example
$Y Substitutes the current 2-digit year 2014 = 14
$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
$s Substitutes the current second 34 = 34
NOTE: All the symbols start with the dollar sign ($) 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, 2013 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
NOTE: Time and Date will need to be reconfigured on power cycle.
