*1 Date and/or time can be added in any format by using the following character strings.
 Year: YYYY for four-digit expression; YY for two-digit expression
 Month: MM
 Day: DD
 Day of the week: ddd (Sunday: Sun, Monday: Mon, Tuesday: Tue, Wednesday: Wed, Thursday: Thu, Friday: Fri, Saturday: Sat)
 Hour: hh
 Minute: mm
 Second: ss
Example: for June 18, 2014 (Wednesday), 09:30:15, YYYYMMDDdddhhmmss  20140618Wed093015_00000001.bin
Also when using the additional information simply as a character string rather than the above format, any character string can be added
by enclosing it with double-quotation marks (" ").
Example: when adding the character string "address" to the file name, "address"  address_00000001.bin can be used.
*2 Maximum of 64 one-byte characters (including an underscore (_), a serial number (eight digits), a period, and an extension) can be
used.
However, when a character string that contains double quotation marks (" ") is specified, the maximum number reduces by the number
of the double quotation marks.
In the Process CPU (redundant mode), since three characters of an identifier are added to a file name at system switching, the save file
name should be within 61 one-byte characters (including underscores (_), a serial number (eight digits), a period, and an extension).
( Page 500 Switching to a storage file)
*3 Reducing the setting value results in frequent file switching, so that it is possible that the scan time and/or the device/label access
service processing time can be extended.
