User-set Allocations without the CX-Integrator
With CJ-series DeviceNet Units, you can allocate remote I/O communications in any area without
the CX-Integrator simply by using device variables for CJ-series Unit.
If you use the CX-Integrator, you can change the node address order for more flexible I/O alloca-
tions. This feature enables the proper area allocation for any application and simplifies program-
ming, which helps you make effective use of the CPU Unit Area on the memory used for CJ-series
Unit.
Note

for details.
z
Slave Functions
You can use CJ-series DeviceNet Units as both masters and slaves, and you can execute master
and slave communications either separately or simultaneously. A Unit that is used as a slave sup-
ports fixed and user-set allocations.
Note
Refer to
Remote I/O Slave Communications
for details.
z
Multiple Controllers in a Single Network
You can connect multiple DeviceNet Units in a single network for message communications between
CPU Units as well as for remote I/O communications between Controllers and slaves in multiple
groups. This feature allows a DeviceNet to be used as a common bus that can integrate all types of
control with less wiring.
