(Note-1): Range of positioning dedicated devices differs depending on the OS. For details, see Chapter 3.
(Note-2): No. of extension fide register blocks varies depending on the setting of program capacity, No. of file registers, or No. of comments.
(Note-3): The expansion comments are not stored in the internal memory of the CPU.
(Note-4): The year data by the clock element is only the lower two digits of the year.
When used in sequence control, the data must be compensated for the sequence program in some applications of using the data.
