Slave bit input and output data, and status data (status, set-
tings, participation, and disconnection) are set using software
settings (areas and addresses) from the CX-Integrator. The
sizes allocated are also set using software settings (number of
nodes) from the CX-Integrator.
Note Words are always allocated to Slave Units in ascending
order from node address 0. Nothing can be allocated to
unused node addresses. If the number of nodes set from
the CX-Integrator is n, then Slave Units are allocated
from node address 0 to n-1.
