DeviceNet Installation and Programming Manual
2.2 DeviceNet Network Connections
Feed DeviceNet network cable through cord grip.
Allow enough cable for routing along inside of
enclosure to connector on the DeviceNet module.
Connect network cables to connector on the DeviceNet
module (see Figure 2-4), then use cable ties to secure
network cables to the cable tie mounts.
Table 2-1shows the wiring color codes used for
DeviceNet connections.
Note
Verify the color-coding or wiring scheme for
your network equipment before wiring to the
DeviceNet Interface.

Baud Rate
Switches 1 and 2 set the baud rate of the DeviceNet
network. Use Table 2-2 to select the correct switch
settings for the network.

Node Address (MAC ID)
Switches 3–8 set the node address (MAC ID) of the
DeviceNet interface. Use Table 2-3 on page 5 to select
the switch setting for the node address.
Note
Setting a switch ON acts as a logical “1” and
that SW1-3 represents the most significant bit
(MSB) of the node address.
