(c) Start XY setting
When the start XY has not been entered, the CPU module automatically assigns it.
automatically assigns the start XY if it is not set. For this reason, the start XY setting of each slot
may be duplicated with the one assigned by the CPU module in the case of 1) or 2) below.
1) Start XY values are not in the correct order.
2) Slots with and without the start XY setting (automatically assigned slot) are mixed
An example of start XY duplication is given in Figure 4.9 below.

Figure 4.10 Start XY set by above (Figure 4.9) I/O assignment
Do not set duplicated start XY for each slot.
Duplication of start XY will result in an error ("SP. UNIT LAY ERR.").
Setting "Empty" and "0" to Type and Points respectively even occupies one slot.
To set on and after the specific slot unoccupied, set the number of slots in Detail mode. (
