The following functions are specific to the
L
on
W
orks
device
(in this case, the
L
on
W
orks
communication module). These
functions are used for maintenance and testing. A network
management tool such as Echelon’s LonMaker
®
software is
typically used to issue the network commands.
The Network “Wink” Command
A wink command is initiated by the BAS or through the
L
on
W
orks
commissioning software. The “wink” identification
function allows verification of an individual unit controller
network address without having to physically open the unit’s
access panels. The Wink command can be used during all
operating and non-operating (ex. Alarm) modes except for the
following conditions:
• Brownout Mode
• Emergency Shutdown
• Defrost process
Upon receiving a wink command from a network management
node, the unit controller exhibits the following identification
sequence (all occur simultaneously):
•
Room Sensor LED: flashes ON for 3.0 sec, OFF for 3.0
sec for 15 total seconds, unless an alarm condition exists.
• Fan: The fan turns off for 5 seconds, turns on for 5
seconds, then off again for 5 seconds.
Offline
When the
L
on
W
orks
communication module receives a
network command to go Offline, the unit controller continues to
operate but communication is suspended except for network
management messages.
Online
When the
L
on
W
orks
communication module receives a
network command to go Online, network messaging is
restored.
Reset
When the
L
on
W
orks
communication module receives a
network command Reset command, it performs the following:
1. Sends a command to the unit controller to perform a
warm reset, maintaining non-volatile memory.
2. Resets the Neuron processor.
