NOTE
1 The maximum number of steps assumes programming using basic instructions. The maximum
number of steps varies according to the status of functional instruction use.
2 The total sequence program size (including all of the ladders, symbols/comments, and
messages) must not exceed the capacity of the sequence program storage memory. If the size
of any of the ladders, symbols/comments, or messages is greater, the maximum allowable size
of the others may be limited.
