Event Handlers

NetLinx Programming Language Reference Guide
If the event handler is specified using an array for DEV, CHANNEL, or a DEVCHAN array, GET_LAST
can be used to determine which index in the array caused the event to run.
Data events

DATA_EVENT[DEVICE] or DATA_EVENT[DEV[ ]]
{
COMMAND:
{
// COMMAND event handler
}
STRING:
{
// STRING event handler
}
ONLINE:
{
// ONLINE event handler
}
OFFLINE:

// OFFLINE event handler
}
ONERROR:

// ONERROR event handler
}
}
