Section 1 Specications
(2) Main unit with 32/40/60 points
Notes:
1) You can increase or decrease the size of the standard memory (excluding high-speed memory), retain memory, user FB
instance memory, and system FB instance memory by the loader. The default values are shown in the gure above. For
details, see “3-3-2 CPU memory size denition.”
2) The rst 4K words of the standard memory (M) are used as a high-speed memory for high-speed access. You cannot
change the size.
3) For the input/output address assignment, see “1-4 I/O Address Assignment.”
4) You can set the initial values of the standard memory and retain memory using the free space of the program memory.
Initial values require 2.5 steps per variable.
5) The initial value setting memory is automatically allocated according to the size of the user FB instance memory and uses
the area of user FB memory x 1 1/8 words.
