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.
C o n n e c t n e t w o r k c a b l e s t o c o n n e c t o r o n t h e
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.
Verify the color-coding or wiring
scheme for your network equipment before wiring to the
DeviceNet Interface.
2.3 DIP Switch Configuration
A DIP switch is used to configure the DeviceNet
network baud rate and node address. Figure 2-7 shows
the DIP switch assignments.
Figure 2-7. DIP Switch Assignments
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.
