Rockwell Automation 22-COMM-L LonWorks Adapter - Manual (Page 32)

4-4 Configuring the Network
This section describes the basics of node operation.
WINK (What is a WINK?)
WINK is a network command that verifies communication with a node.
The NET A indicator will flash to indicate that a WINK was received.
The LED will flash red according to the following sequence:
• 3 fast flashes
• OFF for 1 second
This sequence is repeated 10 times.
If the Node is Offline
If node is brought offline it will not accept any NVI (Network Variable
Inputs) settings or update NVOs (Network Variable Outputs). The
adapter uses the setting in Parameter 09 - [Idle Flt Action] and issues a
command to the drive. NCI (Network Configuration Input) variable
updates will be accepted but not forwarded to the drive until the node
goes online and/or is reset.
If the Node is Online
The node accepts NCI and NVI settings and updates NVOs.
Two parameters in PowerFlex 40/400 drives must be set to enable the
drive to operate on a LonWorks network:
• Set drive parameter P036 - [Start Source] to “5” (Comm Port)
• Set drive parameter P038 - [Speed Reference] to “5” (Comm Port)
