I/O NUMBER ASSIGNMENT
(2) Precautions for the number of mounted modules
Mount modules within the range of the allowed number of slots.
Even if the total number of slots for a main base unit and extension base unit is
greater than the number of available slots (for example, six 12-slot base units are
used), no error will occur when modules are mounted in slots whose number is within
a valid range.
An error ("SP. UNIT LAY ERR.") will occur if any module is mounted after the slot
exceeding the number of available slots.

When the GOT has been bus-
connected, one slot of extension
base 1 is used.
Also one GOT occupies 16 I/O
points.
When using the GOT, consider
the number of slots and the
number of I/O points.
Refer to the GOT Manual for
details of busconnecting the GOT.
