Notes
• If there are any empty slots between the CPU unit and the
Computer Communication Unit, check to see if an I/O area has
been allocated for the empty slot(s).
• When I/O mount allocations are made, or automatic allocation
is carried out, 16 points are automatically allocated to each
empty slot.
• If the CPU unit being used is a dual−module type, make sure
any occupied I/O areas incorporated in the CPU unit are also
checked.
For information on I/O allocations, please refer to the “FP2/FP2SH Hardware Manual”.
