NOTE
1 This is the number of ladder steps for the program only with
basic instructions. The use of functional instructions may
vary the number of ladder steps.
2 These have no limit of size for each. However, the total size
of sequence program (the sum total of ladder,
symbols/comments, messages, etc.) never exceed the
storage size of sequence program. The size of them
influences the capacity of others.
3 The one and only I/O of the FANUC Series 15i is the I/O
Link.
