Section
Design
Allocating any
words for
remote I/O
Not in order of
node
addresses
Set with the use of the CX-Integrator.
Note
Allocations with the use of CX-Integrator:
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.
4-4-1 Settings
through CX-
Integrator
In order of
node
addresses
Set with the use of the device variables for CJ-
series Unit.
(Master user-set Allocations Setup Table and Allo-
cation Size Setup Table)
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.
4-4-2 Settings
through Device
Variables for
CJ-series Unit
(Master User-
set Allocations
Setup Table)
Using the Unit as a slave
Set with the use of the device variables for CJ-
series Unit.
5-1 Slave
Remote I/O
Communica-
tions
Performing message communi-
cations between controllers to
which DeviceNet Units are
mounted
Execute communications instructions from the
user program.
Section 6 Mes-
sage Commu-
nications
Mounting multiple DeviceNet
Units using master communica-
tions to a single controller
3 Units max. with fixed allocations
16 Units max. with user-set allocations
4-1 Master
Remote I/O
Communica-
tions
Mounting multiple DeviceNet
Units using slave communica-
tions to a single controller
3 Units max. with fixed allocations
16 Units max. with user-set allocations
5-1 Slave
Remote I/O
Communica-
tions
Connecting multiple controllers
(master communications) in a
network
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.
5-1 Slave
Remote I/O
Communica-
tions
Connecting a single Master con-
troller and multiple Slave control-
lers in a network
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)
5-1 Slave
Remote I/O
Communica-
tions
Sending DeviceNet explicit mes-
sages
Set the command code to 2801.
6-2 Sending
Explicit Mes-
sages
Setting the node address for a
DeviceNet Unit
Set the rotary switches on the front of the
DeviceNet Unit.
Setting the baud rate for the
DeviceNet Unit
Set the DIP switch on the front of the DeviceNet
Unit.
Stopping remote I/O communi-
cations for communications
errors
Set the DIP switch on the front of the DeviceNet
Unit.
Storing OUT data in slave I/O
memory for communications
errors
Set the DIP switch on the front of the DeviceNet
Unit.
