network has been processed by the LonTalk API. This call
indicates that the network variable value has already been
updated, and allows your host application to perform any
additional processing, if necessary.
LonOffline() A request from the network that the device go offline.
Installation tools use this message to disable application
processing in a device. An offline device continues to
respond to network management messages, but the

is suspended. When this function is called, the Echelon
Smart Transceiver or Neuron Chip is already offline and the
LonTalk Stack application need only take
application-specific action.
LonOnline() A request from the network that the device go online.
Installation tools use this message to enable application
processing in a device. When this function is called, the
Echelon Smart Transceiver or Neuron Chip is already
online and the LonTalk Stack application need only take
application-specific action.
LonReset() A notification that the device has been reset.
LonServicePinHeld() An indication that the service pin on the device has been
held for some number of seconds (default is 10 seconds).

pin’s being held.
LonServicePinPressed() An indication that the service pin on the device has been
pressed. Use it if your application needs notification of the
service pin’s being pressed.
LonWink() A wink request from the network.
Installation tools use the Wink message to help installers
physically identify devices. When a device receives a Wink
message, it should provide some visual, audio, or other
indication for an installer to be able to physically identify
this device.
