With this mode, I/O ports are not used and the I/O data for Slave Units is assigned to the
memory used for CJ-series Units. The area and first address for each of the following is set
in the software settings from the CX-Integrator: WORD OUT Data for Word Slave Units,
WORD IN Data for Word Slave Units, BitOUT Data for Bit Slave Units, BitIN Data for Bit
Slave Units, and status (status, settings, participation, and disconnection). The size of
memory that is allocated for each is set in the software setting from the CX-Integrator. AT
specifications for user-defined variables must be made for the memory locations that are
set in the software settings.
Note The allocations for the Slave Units are fixed and are in order from node address 0.
Even if some of the node addresses are not used, the allocations cannot be changed.
If the number of nodes that is set from the CX-Integrator is n, node address 0 to node
address n−1 are allocated.
