Cutler-Hammer
®
9000X drives from Eaton Electrical
®
can be connected to the LonWorks
®
network using a fieldbus board. The drive can then be controlled, monitored and
programmed from the Host system.
The LonWorks board shall be installed in slot E on the control board of the drive.
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. The Cutler-Hammer OPTC4 option
board uses only Standard 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 different 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.
WARNING
Internal components and circuit boards are at high potential when
the drive is connected to the power source. This voltage is
extremely dangerous and may cause death or severe injury if you
come into contact with it.
