Note Allocations using allocated DM Area words:
Order of node addresses and two blocks,
OUT 1 and IN 1.
108
Not in order of
node
addresses
Set using the configurator.
Note Allocations using Configurator: Any node
address order and four blocks, OUT 1, IN 1,
OUT 2 and IN 2. Allocation is much easier
using a wizard.

Using the Unit as a slave Set using the allocated DM Area words. 122
Performing message communi-
cations between PCs to which
DeviceNet Units are mounted
Execute communications instructions from the user
program.
134
Mounting multiple DeviceNet
Units using master communica-
tions to a single PC
3 Units max. with fixed allocations
16 Units max. with user-set allocations
92
Mounting multiple DeviceNet
Units using slave communica-
tions to a single PC
3 Units max. with fixed allocations
16 Units max. with user-set allocations
122
Connecting multiple PCs (master
communications) in a network
Supported by user-set allocations using allocated
DM Area words or user-set allocations using the
Configurator.
122
Connecting a single Master PC
and multiple Slave PCs in a net-
work
Set multiple PCs to Slave mode from the allocated
DM Area words or the Configurator.
Note Up to 64 Units may be on a network.
(Example: 1 Master PC and 63 Slave PCs)
122
