Technical OverviewThe LonWorks communications structure is similar to that of a local area network (LAN) in thatmessages are continually exchanged between a number of processors. A LonWorks system is alocal operating network (LON). LON technologyoffers a means for integrating various distributedsystems that perform sensing, monitoring, control, and other automated functions. A LON allowsthese intelligent devices to communicate with one another through a variety of communicationsmedia using a standard protocol.LON technology supports distributed, peer-to-peer communications. That is, individual networkdevices 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 whichcontain commands and status information that trigger actions. LONperformance is viewed in termsof transactions completed per second and response time. Control systems do not require vastamounts of data, but they do demand that the messages they send and receive are absolutelycorrect.Data are transported by means of standard network variable types (SNVTs) which provide a well-defined interface for communication between devices from different manufacturers. Functionalprofiles defining the functionality and network variables for a particular family of devices (e.g.frequency converters, pumps etc.) are also available, and supported by the LonWorks option.3.1.3. AssumptionsThese operating instructions assume, that the Danfoss LonWorks option is used in conjunctionwith a Danfoss FC 100 frequency converter. It is also assumed that the installed controller supportsthe 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.VLT® FC 100 LonWorks 3.
