Network Identification and Node Configuration
The
L
ON
W
ORKS
Option Card
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 un-configured node can be recognized by the SERVICE LED blinking at 2Hz.
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 LED’s 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.
