Note
1. Be sure that the same words are not allocated to more than one Unit. For example, if you set a 64-point
Unit to I/O number 0, you cannot use I/O number 1 for any Unit.
2. The above words are also allocated to Group-2 High-density I/O Units. Be sure that the same words are
not allocated to more than one Unit.
