ACC-SVN100A-EN • LonTalk Communication Interface 61
A
Application software
Software within the LCI-C Neuron processor that defines
its program ID and network variables
B
binding (LonTalk)
On LonTalk communication links, a binding links a network
variable in one device with a network variable in another
device, thereby allowing the devices to share common
information, such as the same setpoint or temperature
sensor value. This type of binding is different from a
binding on a Tracer UC800 Machine bus.
C
configuration (Tracer UC800 controller)
Refers to the use of the Tracer TU service tool to select
the chiller type, tonnage, and other options, of a Tracer
UC800 controller. It also refers to adding the LCI-C as one
of these options, which is necessary for the LCI-C LLID to
be installed properly on the Tracer UC800.
F
flash download wizard (Rover)
A step-by-step process with Rover software to change
(flash) the application software of the LCI-C.
I
IPC
Acronym for inter-processor communications.
L
LCI-C Extension software
Trane LCI-C software that implements network variables
from both the LonMark Chiller Functional Profile and Trane
Chiller Extension.
LCI-C Profile Only software
The initial release of Trane LCI-C software, which
implements only the network variables described in the
LonMark Chiller Functional Profile.
low-level intelligent device (LLID)
An electronic board that is configured and installed on the
Tracer UC800 Machine bus in order to fulfill a function for
the chiller controller. The LCI-C LLID allows the Tracer
UC800 to communicate on a LonTalk network.
LonMark Chiller Functional profile
A standard list of network variables, mandatory and
optional, that LonMark defines for chiller controller
communications on a LonTalk network.
LonMark communications interface (LCI)
An interface developed by Trane to allow unit controllers
to communicate using LonTalk protocol.
LonMark International
LonMark International is a global membership organization
created to promote and advance the business of efficient
and effective integration of open, multi-vendor control
systems utilizing ANSI/EIA/CEA 709.1 (LonTalk) and
related standards.
LonTalk network
A collection of LonTalk devices that communicate and
interact with one another.
LonTalk Protocol
An interoperable protocol developed by the Echelon
Corporation and named as a standard by the Electronics
Industries Alliance (EIA-709.1). It is packaged on a Neuron
processor that is on the LCI-C LLID.
M
Machine Bus/the binding process (formerly the
IPC3 communication bus)
On a Tracer UC800 Machine bus, the bindings process is
performed with the Tracer TU service tool. The process
installs the LLIDs on the bus so that the LLIDs can
communicate with the main processor and are able to
function as intended.
main processor (Tracer UC800 controller)
The processor contained within the control panel of the
chiller to control the chiller and coordinate communication
of the LLIDs on the Machine bus. It stores the
configuration of the UC800 and what LLIDs are expected
to be on the Machine bus.
