Nomenclature and Functions Section 2-1
Note 1. The node address is set to 63 at the factory.
2. Any node address from 0 through 63 can be set as long as it hasn’t been
set on another slave node.
3. If the node address is the same as one set on another node, a node ad-
dress duplication error will occur and it won’t be possible to start up net-
work communications.
4. Node address 0 cannot be used for FINS message communication. Use a
node address other than 0 for FINS message communication.
DIP Switch The DIP switch on the front of the DeviceNet Unit is used to set the baud rate,
whether communications will be continued or stopped when a communica-
tions error occurs, and whether to hold or clear the remote outputs when a
communications error occurs in the slave function.
The settings of the DIP switch pins are shown in the following table. All pins
are set to OFF at the factory.
Baud Rate
Pins 1 and 2 are used to set the baud rate as shown in the following table.
Note 1. Always turn OFF the PC before changing the DIP switch settings.
2. Set the same baud rate on all of the nodes (Master and Slaves) in the Net-
work. Any slaves with baud rates different from the master’s rate won’t be
able to participate in communications and may cause a communications
error between nodes that have been set properly.
