Installation 1-9
# Network Identification and Node Configuration
The LONWORKS Option is shipped unconfigured. This implies that the application is loaded and communications parameters are defined
but the option has not been installed on the network. On power up. An unconfigured node can be recognized by the SERVICE LED
flashing at 0.5Hz.
Network identification is accomplished with an installation tool. Unique network identities are established by pairing “logical” addresses
with a device’s 48-bit Neuron ID.
! SERVICE Button
Each option card has a Service Button. If using a configuration tool utilizing this feature, press the Service Button when prompted to
do so. When pressed, a broadcast message is sent which contains the Neuron ID and program ID. This uniquely identifies the node on
the network. This method works best for small networks or with portable installation tools.
! Find and Wink
When it is impractical to press each node’s Service Button for installation (e.g. in large networks or a node is physically enclosed), the
“find and wink” installation method is useful. With this method, the installation tool queries the network for all unconfigured nodes.
Nodes respond with their Neuron ID and a logical address is assigned. A “wink” command can then be sent to each logical address. In
response to this command, the TRANSMIT and RECEIVE LEDs will blink rapidly for several seconds. In this manner, the exact
physical location of each node can be identified.
! Reclaiming a Node
$ A node can be “reclaimed”, or returned to its unconfigured state, as follows:
$ Remove power from the drive and wait for the charge lamp to be completely extinguished.
$ Press and hold the Service Button.
$ Re-apply drive power, continuing to press and hold the Service Button.
After approximately 5 seconds, the SERVICE LED should begin flashing at a 0.5 Hz rate, indicating the unconfigured state. This
procedure sets both domain table entries to “undefined” and sets the channel ID to 0.
