9.3.2 Allocation of System Ports
When using a DeviceNet master board, you may choose a system port allocation
from the following five patterns. For the choosing procedure, refer to Subsection 9.4.6
“Allocating Ports Dedicated to the DeviceNet Master.”
Note that “Allocation of DeviceNet slave system I/Os in compatible mode” and
“Allocation of DeviceNet slave system I/Os in standard mode” are reserved for future
expansion, so their allocations are the same as that of “All user ports.”
