Connecting a single Master PLC
and multiple Slave PLCs in a net-
work
Sending DeviceNet explicit mes-
sages
Setting the node address for a
DeviceNet Unit
Setting the baud rate for the
DeviceNet Unit
Stopping remote I/O communica-

In order of node Set using the allocated DM Area words.
addresses (Master User Allocations Setup Table and Alloca-
tion Size Setup Table)
Note Allocations using allocated DM Area words:
Order of node addresses and two blocks,
OUT 1 and IN 1.
Not in order of Set using the configurator.
node
Note Allocations using Configurator: Any node
addresses
address order and four blocks, OUT 1, IN 1,
OUT 2 and IN 2. Allocation is much easier
using a wizard.
Set using the allocated DM Area words.
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 using allocated
DM Area words or user-set allocations using the
Configurator.
Set multiple PLCs to Slave mode from the allo-
cated DM Area words or the Configurator.
Note Up to 64 Units may be on a network.
(Example: 1 Master PLC and 63 Slave
PLCs)
Set the FINS 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.
Set the DIP switch on the front of the DeviceNet
Unit.
Set the DIP switch on the front of the DeviceNet
Unit.
