Technical Overview
The LonWorks communications structure is similar to that of a local area network (LAN) in that messages are
continually exchanged between a number of processors. A LonWorks system is a local operating network (LON).
LON technologyoffers a means for integrating various distributed systems that perform sensing, monitoring,
control, and other automated functions. A LON allows these intelligent devices to communicate with one another
through a variety of communications media using a standard protocol.
LON technology supports distributed, peer-to-peer communications. That is, individual network devices can
communicate directly with one another without the need for a central control system. A LON is designed to
move sense and control messages which are typically very short and which contain commands and status
information that trigger actions. LONperformance is viewed in terms of transactions completed per second and
response time. Control systems do not require vast amounts of data, but they do demand that the messages
they send and receive are absolutely correct.
Data are transported by means of standard network variable types (SNVTs) which provide a well-defined inter-
face for communication between devices from different manufacturers. Functional profiles defining the func-
tionality and network variables for a particular family of devices (e.g., adjustable frequency drives, pumps, etc.)
are also available and supported by the LonWorks option.
Assumptions
This instruction manual assumes that the Trane LonWorks option is used in conjunction with a Trane TR200
adjustable frequency drive. It is also assumed that the installed controller supports the interfaces described in
this document and that all the requirements stipulated in the controller, as well as the adjustable frequency
drive, are strictly observed along with all limitations therein.
Hardware
This manual relates to the
TR200 LonWorks
LonWorks option MCA115
, type no. 130B1467 (coated).
