Note Allocations with the use of CX-Integrator:
addresses
Any node address order and two blocks from
OUT 1, IN 1, OUT 2 and IN 2. Allocation is
much easier with the use of a wizard.

Note Allocations with the use of device variables
for CJ-series Unit: Fixed node address order
and one block from OUT 1 and IN 1.
Set with the use of the device variables for CJ-
series Unit.
Execute communications instructions from the
user program.
3 Units max. with fixed allocations
16 Units max. with user-set allocations
3 Units max. with fixed allocations
16 Units max. with user-set allocations
Supported by user-set allocations with the use of
device variables for CJ-series Unit or user-set allo-
cations with the use of the CX-Integrator.
Set multiple Controller to Slave mode from the
device variables for CJ-series Unit or the CX-Inte-
grator.
Note Up to 64 Units may be on a network. (Exam-
ple: 1 Master Controller and 63 Slave Con-
trollers)
Set the command code to 2801.
Set the rotary switches on the front of the
DeviceNet Unit.
Set the DIP switch on the front of the DeviceNet
Unit.
