Connect Communication
Connectors Colored stickers on the communication connector match the colors of the wires
to be inserted. Check that the colors of the wires match when wiring the
connectors. The colors are as follows.
The internal power for the module is supplied from the communication power
supply (V+, V-).
Set the Node Address To set the node address, follow this procedure.
Figure 23 - Sample Node Address Digits
1. Set the node address by using the two rotary switches on the front panel of
the module, noting that the default setting is 63 and a value between
00…63 is valid for proper use.
2. Use the left rotary switch to set the tens digit of node address (decimal).
3. Use the right rotary switch to set the ones digit.
If the node address switches are set from 64…99, the node address needs to be set
from RSNetWorx for DeviceNet software.
