3) File name in a sequence program
How to specify a file name in a sequence program differs depending on the
CPU module.
• For High Performance model QCPU, Process CPU, and Redundant CPU
Since the single-byte capital letters are distinguished from the single-byte
small letters, specify the file name with capital letters.
* "ABC" and "abc" are distinguished.
• For Universal model QCPU
Since the single-byte small letters and the single-byte capital letters are
not distinguished, specify the file name with either letters.
* Both "ABC" and "abc" are treated as "ABC".
Remark
Since the double-byte capital letters are distinguished from the double-byte small
letters, specify the file name with the capital letters.
In double-byte letters, "ABC" and "abc" are distinguished.
(b) Date, time
The date and time when a file was written to the CPU module by GX Developer.
Note that the indicated date and time are those set on GX Developer (personal
computer).
(c) Size
The file size of when it was written to the CPU module using GX Developer is
displayed in units of bytes. (Click the button on the screen
displayed by selecting [Online] [Read from PLC] to display the latest data.)
At least 64 bytes (136 bytes for program files) are added to the file size created by
users, except for file register files.
