2. LonWorks - general info
Drive frequency converters can be connected to the LonWorks ® network using a fieldbus
board. The converter can then be controlled, monitored and programmed from the Host sys-
tem.
LONWORKS technology has been developed by Echelon Corporation. LONWORKS network
is used in applications like industry and building automation, controlling household electronics,
medical instrumentation and many others. The target of the LONWORKS network is to provide
a common vendor independent communication network for intelligent devices.
In a LONWORKS network, no central control or master-slave architecture is needed. Nodes on
a network communicate with each other using LonTalk ® protocol. Interoperable nodes use
Standard Network Variable Types (SNVT) for communicating over the network. The definition
of an SNVT includes units, a range, and an increment. Honeywell option board uses only Stan-
dard Network Variable Types for the data types.
All network variables are either input (data is coming from the network to the device) or output
(data is sent to the network by the device) network variables. When network variables on dif-
ferent nodes on the network have been bound together by an installation tool, passing of data
is automatic between the right nodes. Only the same type of network variables can be bound
together, so it is very important to have compatible interfaces.
