11.1 Items to be examined for program creation
To create a program with the CPU module, the program capacity, the number of device
points used, etc. must be determined in advance.
(1) Program size considerations
Consider whether a program can be stored within the program capacity that can be
executed with CPU modules (14 k steps) or not. (
Section 5.3.3)
(2) Applications of devices and setting of their numbers of points
Consider the applications of the devices used in a program and their number of
points. (
CHAPTER 9)
(3) Boot operation considerations
When boot operation is executed in TEST MODE, set the PLC parameter boot file
settings.
(In SAFETY MODE, execute boot run regardless of the PLC parameter boot file
settings.)
