(2) 7-Segment LED for node address/error code indication (NA/ERROR)
If the DN311 is transmitting data normally to slave devices, this LED indicates the
node address of the local station.
Supplementary Note
Node address : The node identification number that each of the DeviceNet devices
In the following cases, module or network status is displayed by combined indications of
this LED and the module status and network status LEDs.
• A trouble has occurred on the DN311 or on the network.
• An error has occurred due to a request from the S controller.
(Parameter setting, operation mode, etc. are controlled as requested by the S
controller.)
• The DN311 has run down.
See 6.2 Indications of the 7-Segment LED for the combined indications and
meanings of this LED and the module status and network status LEDs.
(3) DIP switches for operation mode/communication rate setting
These DIP switches are used for setting the DN311 in run mode in the event of a
busoff and a communication rate on the network (500 kbps/250 kbps, 125 kbps).
The meanings of the DIP switches and the method of their setting are described in
3.2 Setting the Switches.
(4) Rotary switches for node address setting (NA-H/NA-L)
These switches are used for setting node addresses in a DeviceNet network to which
DN311s are connected.
A DN311 can have a node address within the range of 0 to 63 (decimals) unless it is
identical with that of another node (slave device) on the network.
The method of setting the rotary switches is described in 3.2 Setting the Switches.
(5) Test connector
This connector is for maintenance only. You may not use it.
(6) Device connector (for DeviceNet connection)
This connector is for connecting DeviceNet cables to the DN311. The method of
connecting cables is described in 3.4 Connection to the Network.

(nodes) connected to a network has. The node address range is from 0
to 63 in decimals. Each of the nodes connected to a DeviceNet
network must have a node address unique to it.
