Allocation
of I/O
Address in
Expansion
base
Start address of input and output point is determined by the station
number set in the expansion driver module.
Each slot of the base is allocated 64 points (fixed), irrespective of the
type of module mounted.
Special modules can be mounted in any position. Unlike digital I/O
modules, a special module is not allocated to any I/O address. A special
module is controlled by a dedicated function block and the address is
automatically allocated to the memory.
For instance, the I/O number of 12 slot base is allocated as follows:
Allocation Only communication module is allowed in the main base. Hence, I/O
addressing is not required. However, same number of points (that is, 768
