Node Operations

The following sections describe the basics of node operation.

WINK (What is a WINK?)

WINK is a network command that verifies communication with a node. The
NET A status indicator flashes to indicate that a WINK was received. This
LED flashes 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 the node is brought offline it does not accept any NVI (Network Variable
Inputs) settings or update NVOs (Network Variable Outputs). The adapter
uses the setting in Parameter 8 - [Idle Flt Action] and issues a command to
the drive. NCI (Network Configuration Input) variable updates are 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.
