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 Maximum points of machine interface contain the point of Built–in I/O. Built–in I/O has DI 96
points, DO 64 points and it uses group 0 of I/O Link.
4 Only Distribution I/O Operator’s Panel I/O Modules(Input 48points / Output 32points) can be
connected. Two Distribution I/O Operator’s Panel I/O Modules is available.
