3.1.2 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 interface for communication between devices
from different manufacturers. Functional profiles defining the functionality and network variables for a particular family of devices (e.g. frequency con-
verters, pumps etc.) are also available, and supported by the LonWorks option.
3.1.3 Assumptions
These operating instructions assume, that the Danfoss LonWorks option is used in conjunction with a Danfoss FC 100 frequency converter. 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 frequency converter, are strictly observed along with all limitations therein.
