5.5.4.2 File Name Rule for Message Data

There are two types of file naming conventions for message data, depending on the method for specifying the language.
Although either method can be selected, method (2) is recommend, as it works with the language specification for the setting
display screen.
For the user safety sequence, the message file cannot be used.
(Method 1) Specify bits 0-2 (3 bits) of bit selection parameter #6453 (Language selection method using only the PLC).
(Method 2) Specify with the display language selection parameter (Base specification parameter #1043 (Method linked with
language selection on the setting and display screens)).
File naming convention
Method (1)
M N X x x x x x . W P G
Method (2)
M N N x x x x x . W P G
The 6- or 5-character string above can contain half-width alphanumeric characters, hyphens (-), and
underscores (_).
The extension is automatically added to indicate the file type.
The first character is reserved to indicate the data type.
The file name of the stored message file determines which method is valid.
If there are both files meeting condition 1 and files meeting condition 2, method 1 is valid.
Condition 1: If the first 2 characters of the file name are "M + 1-digit number", method 1 is valid.
Condition 2: If the first 3 characters of the file name are "M + 2-digit number", method 2 is valid.
Note
(1) Files of a structured project are named their program file name, not names of POUs (program blocks).
(2) When you input a reserved character or numeric characters, rename the program file.
 Method 1
Language is selected by three bits (bit 0-2) of Bit selection parameter #6453; the number corresponds to the number in the
message file name.

(*1) The "Xxxxxx" part of a file name consists of up to 6 one-byte alphanumerical characters, hyphen (-) and underline (_).
The third character X must be a non-numeric character. (To avoid being confused as method 2)
(*2) When the multi-project function is active, one file for a language can be stored for each project.
The total number of projects when the multi-project function is active.
The total number of files for device comments+ messages+ and symbolic information.
